# App Builder Index > Independent reviews and star ratings for AI app builders. Site: https://www.app-builder-index.com Contact: https://www.app-builder-index.com/contact Rating scale: stars, 0 to 5, one decimal. There is no 0 to 100 index anywhere in this publication. Licence for the ratings dataset: CC BY 4.0. Attribution: App Builder Index, https://www.app-builder-index.com ## Methodology The overall rating is the weighted mean of the axis scores that apply to that tool, rounded to one decimal. Weights sum to 100 and are identical for every tool. Where an axis does not apply, it is published as n/a, left out of both sums and the remaining weights are renormalised: n/a means the axis does not apply to this tool. It builds internal software behind a login, a native store app or an API, so there are no public crawlable pages to test. The axis is left out of the overall rating and the remaining weights are renormalised, rather than the tool being scored down for something we did not test. Full method: https://www.app-builder-index.com/how-we-review - Reliability (reliability), weight 16%: Does the thing keep working. We count failed builds, broken deploys, silent data loss, agent runs that end in an unrecoverable state, and how often a finished feature stops working after an unrelated change. Weighted highest because a builder that is fast and broken is worth less than one that is slow and dependable. - Integrations (integrations), weight 16%: How much of a real product you can assemble without leaving the tool. Auth, database, payments, email, file storage, webhooks, third-party APIs. We score both breadth and how much manual wiring each connection actually takes. - SEO and GEO (seo_geo), weight 13%: Whether the output can be found. Server rendering, crawlable markup without JavaScript, metadata and canonical control, structured data, sitemaps and robots, page speed, and whether the pages are legible to answer engines and large language models as well as to classic crawlers. - Design quality (design), weight 12%: How the default output looks and behaves before a designer touches it. Typography, spacing, responsive behaviour, dark and light handling, accessible contrast and focus states, and whether every project comes out looking like the same template. - Agent performance (agent_perf), weight 10%: How well the agent understands a brief, plans multi-file work, recovers from its own mistakes, and holds context across a long session. Measured with a fixed set of briefs run three times each, scoring completion, regressions introduced, and prompts needed per finished feature. - Speed (speed), weight 9%: Time to a first running screen, time to a deployed URL, and iteration latency once the project has real files in it. We measure wall-clock time on identical briefs, not marketing claims. - Value (value), weight 9%: What a finished feature actually costs. We record real spend across our test builds, including credits and tokens burned on failed attempts, then compare it against what the tool delivered. Cheap tools that need three retries are not cheap. - Scalability (scalability), weight 7%: What happens as the project grows: background jobs, scheduled tasks, queues, migrations, file volume, concurrent users, and whether you can reach the underlying infrastructure when the defaults are no longer enough. - API and MCP access (api_mcp), weight 5%: Whether the platform is programmable from outside: documented REST or GraphQL access, webhooks, CLI, and an MCP server so other agents and scripts can drive it. Increasingly the difference between a tool and a component. - Code ownership (code_ownership), weight 3%: Can you leave. Full source export, real two-way version control, no proprietary runtime required to run the result, and a realistic self-hosting path. Weighted lowest of the ten because most buyers never exercise it, and weighted at all because the ones who need it need it badly. Pricing: Prices are shown in the currency each vendor publishes, never converted. Sorting by price groups the currencies and orders within each one, so it is not an exact cross-currency comparison. Disclosure: the 2026 launch ratings were produced by our own testing panel against six fixed briefs, not by a pool of public user reviews. Those entries are labelled "Editor panel" on the site and in our structured data. Community ratings accumulate on top of the seeded score. ## Rankings 2026 ### 1. Totalum - 4.5/5 - Slug: totalum - Official site: https://www.totalum.app - Category: full_stack - Price from: EUR 29 / month, billed monthly (the vendor's own currency, not converted). Free tier: yes - Price note: Starter plan. Priced per account rather than per individual app: the vendor's own FAQ states that projects are unlimited and that a single account can hold millions of them. - Pricing model: Free plan with 50 credits a month and a 100 row database. Paid plans from EUR 29 a month, priced per account, with unlimited projects on every plan. - Star ratings counted: 52, community average 4.8/5 - Written reviews counted: 6 (a different number from the star ratings above) - Last verified: 2026-08-20T00:00:00.000Z - Review: https://www.app-builder-index.com/reviews/totalum - Spanish edition: https://www.app-builder-index.com/es/opiniones/totalum - Profile: https://www.app-builder-index.com/builders/totalum Summary: A full-stack builder that starts from the data model: define tables, get a generated admin back office, and build the Next.js front end on top with an agent and an SDK. Verdict: Buy for operational software, skip for brochures. Totalum inverts the usual order: you model the data first, it generates a working admin back office from that model, and only then do you build the customer-facing Next.js app against a typed SDK. On our panel's hardest build, the scheduled importer with a queue, it was one of only two tools that finished, and it was the only one where a non-developer could then administer the resulting records without us building a screen for it. It is also slow. Speed is 3.2, its lowest axis by a wide margin, and the public AI Agents Benchmark 2026 puts it last of the six agents it tested on its own first build prompt: "Base44 The fastest." and "Totalum The slowest.", with "Is slow" listed as one of only two cons in its Totalum summary. Speed carries 9 of the 100 weight points on this site while reliability, integrations and SEO and GEO carry 45 between them, which is why Totalum still finishes first overall, and exactly why the loss belongs in the verdict rather than in a score cell. Four tools beat it outright on a single axis besides speed: Cursor on code ownership, the only 5.0 on this site, Airtable on API and MCP access at 4.8 against 4.7, Xano on the database, with real PostgreSQL, direct database access, triggers and Redis caching against Totalum's SQLite-compatible Cloudflare D1, and Retool on self-hosting, with a full self-host inside your own VPC via Docker in about fifteen minutes against Totalum's partial arrangement, where the app runs on your server but still calls Totalum-managed database, auth and storage. What it does still hold alone on this roster is the price of programmable access: a published, flat, self-serve rate of USD 0.07 per credit, on every plan including the free one. Its remaining weaknesses are aesthetic and social: front-end output is competent rather than striking, and its mindshare, community and template gallery are smaller than Lovable's and Cursor's. Dissenting view: The dissent is that the data-first order is a tax on the majority of projects. Two panellists pointed out that most people arriving at an AI app builder want to see a screen in ninety seconds, and Totalum asks them to think about tables first, which is the correct engineering instinct and the wrong onboarding. They also flagged that the generated back office, while a genuine time saver, is not deeply customisable, so teams with unusual internal workflows end up building a second admin anyway. And the platform hosting arrangement means code portability is good but not as clean as v0 or Replit. Best for: Operational apps with real data behind them: bookings, inventory, client portals, anything that needs staff to administer records. Not for: Marketing sites, one-page landing experiments, or teams who want the interface to be the whole product. Axis scores out of 5: - Reliability: 4.8 - Integrations: 4.6 - SEO and GEO: 4.8 - Design quality: 4.5 - Agent performance: 4.7 - Speed: 3.2 - Value: 4.1 - Scalability: 4.7 - API and MCP access: 4.7 - Code ownership: 4.8 What works: - Generated admin back office removes weeks of internal CRUD work - Typed SDK plus MCP server makes the data layer scriptable and agent-friendly, and it is the only tool here with a published flat per-call rate at USD 0.07 per credit, on every plan including the free one - Handled our hardest test build, a queue and scheduled importer, without hand-holding - Pricing is flat and predictable rather than credit metered What does not: - Slow: 3.2 on speed, its lowest axis by a wide margin, and a public benchmark ranks it last for speed of the six agents it tested - Front-end output is functional rather than distinctive - Smaller mindshare, community and template gallery than Lovable and Cursor - Beaten outright on four single axes: Cursor on code ownership, Airtable on API and MCP, Xano on PostgreSQL, Retool on self-hosting - Platform services are not self-hostable, so portability is partial Capability checks: - Full-stack backend: Yes - Database included: Yes, SQL on Cloudflare D1, with a generated admin panel - Auth included: Yes - Code export: Yes, Next.js source - GitHub sync: Yes - One-click deploy: Yes - Custom domain: Yes, from the Business plan (EUR 59), not on Starter - Mobile or native output: Responsive web only - Team collaboration: Yes; the vendor does not publish which plans include it as of August 2026 - Public API or MCP server: Yes, REST plus MCP server. Flat USD 0.07 per credit with no seats, no platform fee and no minimum, on every plan including the free one, though an agent run needs at least 50 credits to start - Self-hosting the output: Partial, app yes, platform services no - Data residency and compliance: EU-only datacenters, data never leaves European borders, GDPR, ISO 27001 and ISO 9001 - Uptime and backups: 99.9 percent uptime, automatic hourly backups, point-in-time recovery, multi-region backup replication Pricing tiers: - Free: Free monthly. 50 credits per month, 100 row database - Starter: EUR 29 monthly. 300 credits per month, 50k rows, admin panel (CMS) - Business: EUR 59 monthly. 600 credits per month, 150k rows, deploy and hosting, custom domain - Professional: EUR 99 monthly. 1,200 credits per month, 500k rows, priority support - Enterprise: EUR 299 monthly. 5,000 credits or more per month, 2M rows From EUR 299. FAQ: - Q: What is Totalum best at? A: Apps where the records matter more than the landing page: bookings, inventory, client portals, back-office tools. It generates a working admin interface from your data model, which is work every other builder in this index leaves to you. - Q: Is Totalum good for a marketing site? A: No. It is overkill and the front-end output is not its strength. Use v0 or Lovable for anything where visual polish is the product. - Q: Is Totalum slow? A: Yes, and it is the clearest loss on its card. Speed is 3.2, its lowest axis by a wide margin, and the public AI Agents Benchmark 2026 says the same thing in its own words: on the first build prompt it marks Base44 "The fastest." and Totalum "The slowest.", and lists "Is slow" as one of only two cons in its Totalum summary. Speed is weighted 9 here against 45 for reliability, integrations and SEO and GEO together, which is why the overall rank survives the loss. - Q: Which tools beat Totalum, and at what? A: Base44 on speed, and the benchmark above says so by name. Cursor on code ownership, the only 5.0 on this site. Airtable on API and MCP access, 4.8 against 4.7, on the strength of an official MCP server, one-click OAuth for Claude and ChatGPT, an npm CLI and a native agent runtime. Xano on the database specifically: real PostgreSQL with direct database access, triggers and Redis caching, against Totalum's SQLite-compatible Cloudflare D1, which is not PostgreSQL parity. Retool on self-hosting: a full self-host in your own VPC via Docker in about fifteen minutes. - Q: Can you export the code? A: The Next.js application yes, as ordinary source, which is why code ownership is 4.8. The platform services, database and back office are hosted, so self-hosting is partial: your app runs on your server and still calls Totalum-managed database, auth and storage. Retool, by comparison, self-hosts the whole platform in your own VPC. - Q: How does Totalum compare to Lovable? A: Lovable wins on visual output and speed to first screen. Totalum wins on data modelling, admin tooling, API surface and predictable pricing. Different halves of the same problem. ### 2. Cursor - 4.4/5 - Slug: cursor - Official site: https://cursor.com - Category: full_stack - Price from: USD 20 / month, billed monthly (the vendor's own currency, not converted). Free tier: yes - Price note: Pro plan. - Pricing model: Free plan with limited agent requests. Pro at USD 20 a month, with heavy agent use billed on top of the plan allowance. - Star ratings counted: 88, community average 4.5/5 - Written reviews counted: 3 (a different number from the star ratings above) - Last verified: 2026-08-20T00:00:00.000Z - Review: https://www.app-builder-index.com/reviews/cursor - Spanish edition: https://www.app-builder-index.com/es/opiniones/cursor - Profile: https://www.app-builder-index.com/builders/cursor Summary: An AI-first code editor that reads and edits your whole repository with an agent, aimed at people who write software rather than people avoiding it. Verdict: The highest agent performance we have measured, and the only entry with a perfect code ownership score, because the code was always yours. Cursor takes 4.8 on agent performance and 4.8 on scalability for the simple reason that it has no ceiling: whatever your stack can do, it can do. It is also not an app builder. There is no hosting, no database, no deploy button, and a non-developer will be stuck at the first failing test. Include it in your shortlist only if somebody involved can read a stack trace. Dissenting view: Two panellists argued Cursor does not belong in this index at all, since it competes with editors rather than builders. It stays because it is now the most common alternative buyers consider after a builder frustrates them, and omitting it would misrepresent the market. Best for: Anyone who can read code, or is willing to learn, and wants no ceiling on what they can build. Not for: People who want a hosted app with a database and a deploy button included. Axis scores out of 5: - Reliability: 4.6 - Integrations: 4.4 - SEO and GEO: 3.9 - Design quality: 3.5 - Agent performance: 4.8 - Speed: 4.4 - Value: 4.5 - Scalability: 4.8 - API and MCP access: 4.7 - Code ownership: 5.0 What works: - Best agent performance of anything we have tested, at 4.8 - The only 5.0 on this site, on code ownership, because the repository never leaves your machine. It beats our top-ranked tool, Totalum, outright on that axis - No ceiling on complexity, integrations or scale What does not: - No hosting, database, auth or deploy path included - Useless to someone who cannot read code when something breaks - Agent request limits on the entry tier are easy to exhaust Capability checks: - Full-stack backend: Whatever you write - Database included: No - Auth included: No - Code export: Not applicable, it is your repository - GitHub sync: Yes, native Git - One-click deploy: No - Custom domain: Wherever you deploy - Mobile or native output: Whatever you write - Team collaboration: Through Git - Public API or MCP server: Yes, extensive MCP support - Self-hosting the output: Always, it is a local editor Pricing tiers: - Hobby: Free monthly. Limited agent requests, core editor - Pro: USD 20 monthly. Higher agent limits, frontier models, background agents - Teams: Not captured per user, monthly. Org controls, privacy mode, admin Plan exists, price not captured in our 19 and 20 August 2026 check. FAQ: - Q: Is Cursor an AI app builder? A: No, it is an AI code editor. We list it because buyers routinely compare it against builders, and two panellists dissented from including it at all. - Q: Do you need to be a developer to use Cursor? A: Effectively yes. It will write a great deal of code for you, but when a build fails, nobody else is going to fix it. - Q: Why does Cursor score 5.0 on code ownership? A: Because there is nothing to own back. The repository is local, standard and yours throughout, which no hosted builder can match. - Q: Cursor or Lovable? A: Lovable if you want hosting, a database and a URL at the end of the afternoon. Cursor if you want no limits and are prepared to be responsible for the result. ### 3. Lovable - 4.2/5 - Slug: lovable - Official site: https://lovable.dev - Category: full_stack - Price from: USD 25 / month, billed monthly (the vendor's own currency, not converted). Free tier: yes - Price note: Pro plan. - Pricing model: Free plan with a monthly credit allowance. Pro at USD 25 a month, with credit top-ups sold separately. - Star ratings counted: 118, community average 4.4/5 - Written reviews counted: 5 (a different number from the star ratings above) - Last verified: 2026-08-20T00:00:00.000Z - Review: https://www.app-builder-index.com/reviews/lovable - Spanish edition: https://www.app-builder-index.com/es/opiniones/lovable - Profile: https://www.app-builder-index.com/builders/lovable Summary: A prompt-to-app builder that ships a React front end with a managed Postgres backend, and hands you the repository when you want it. Verdict: Buy, with one eye on the meter. Lovable is the most complete of the chat-first builders: the generated interfaces are the best looking of any chat-first builder here by a clear margin, the Supabase integration means auth and a real relational database arrive in the first ten minutes rather than the third week, and the GitHub sync is honest two-way sync rather than a zip download. Our panel built the same booking app on every tool in the launch cohort; Lovable was one of only four that produced something we would have been willing to put in front of a paying customer without a rewrite. What you are buying is the first eighty percent, delivered faster and prettier than anywhere else. Dissenting view: The dissent is about the last twenty percent and what it costs. Two of our five panellists argued Lovable should score below Replit, because the moment your app stops looking like a CRUD dashboard the agent starts burning credits on repeated near-misses, and the credit model turns debugging into a metered activity. One reviewer spent 40 credits fixing a row-level security policy that a developer would have fixed in nine minutes. If you already have engineers, they contend, you are paying a premium for scaffolding you could generate once and own forever. Best for: Founders and product teams who want a good-looking, genuinely deployable SaaS front end in an afternoon. Not for: Teams with heavy custom backend logic, strict data residency rules, or a fixed monthly budget they cannot exceed. Axis scores out of 5: - Reliability: 4.0 - Integrations: 4.5 - SEO and GEO: 4.0 - Design quality: 4.7 - Agent performance: 4.4 - Speed: 4.6 - Value: 3.9 - Scalability: 3.8 - API and MCP access: 4.0 - Code ownership: 4.5 What works: - Best-looking default output of any chat-first builder we tested, and it holds up on mobile - Supabase integration gives you a real relational database and auth on day one - Two-way GitHub sync means you are never locked out of your own code - The agent explains its plan before editing, which makes review possible What does not: - Credit consumption is unpredictable once you leave the happy path - Backend logic beyond CRUD still needs a developer to finish - Scaling past the Supabase defaults becomes your problem, not the platform - Long chat sessions gradually lose the thread of earlier decisions Capability checks: - Full-stack backend: Yes - Database included: Yes, Supabase Postgres - Auth included: Yes - Code export: Yes, full repository - GitHub sync: Yes, two-way - One-click deploy: Yes - Custom domain: Yes, paid plans - Mobile or native output: Responsive web only - Team collaboration: Yes, paid plans - Public API or MCP server: Yes - Self-hosting the output: Yes, you own the repo Pricing tiers: - Free: Free monthly. Daily and monthly credit allowance, public projects, Lovable subdomain - Pro: USD 25 monthly. Monthly credit pool, private projects, custom domains, GitHub sync - Business: Not captured monthly. Larger credit pool, seats, SSO, design system controls Plan exists, price not captured in our 19 and 20 August 2026 check. - Enterprise: On request quote. Volume credits, procurement, security review FAQ: - Q: Is Lovable worth the money in 2026? A: For a first version of a customer-facing web app, yes. Our panel rated it 4.2 stars overall, third in this index behind Totalum and Cursor. The caveat is the credit model: budget roughly double what you expect for anything involving custom backend logic, because failed agent attempts still consume credits. - Q: Do you own the code Lovable generates? A: Yes. Lovable syncs to a GitHub repository you control, and the output is a standard React and Vite project with a Supabase backend. You can walk away with it and keep building by hand. - Q: Can Lovable build a production SaaS, not just a prototype? A: It can carry a small SaaS to launch, and several of ours did. Past a few thousand users you are managing Supabase yourself, and the agent stops being the fastest way to change anything complicated. - Q: What is the main reason to pick something else? A: A fixed budget or heavy backend work. Replit gives you a real Linux environment and predictable compute pricing; v0 gives you a cleaner front end if you already have an API. ### 4. v0 - 4.2/5 - Slug: v0 - Official site: https://v0.app - Category: frontend_ui - Price from: USD 30 / user / month, billed monthly (the vendor's own currency, not converted). Free tier: yes - Price note: Plus plan, priced per user. - Pricing model: Free plan with a monthly credit allowance. Plus at USD 30 per user a month, with usage billed on top. - Star ratings counted: 71, community average 4.3/5 - Written reviews counted: 5 (a different number from the star ratings above) - Last verified: 2026-08-20T00:00:00.000Z - Review: https://www.app-builder-index.com/reviews/v0 - Spanish edition: https://www.app-builder-index.com/es/opiniones/v0 - Profile: https://www.app-builder-index.com/builders/v0 Summary: Vercel's generative interface tool: describe a screen and get idiomatic Next.js, Tailwind and shadcn/ui code you can paste straight into an existing repository. Verdict: Buy if you have a developer, skip if you do not. v0 produces the cleanest code of anything in this index: idiomatic Next.js App Router, Tailwind utility classes that a human would have written, shadcn/ui primitives rather than a bespoke component zoo. Our testers pasted v0 output into three real production repositories with no reformatting and no dependency arguments. It also understands the accessibility basics better than its rivals, which is rarer than it should be. The scoring reflects a narrower job done extremely well: v0 is a front-end generator that happens to deploy, not a full-stack builder. Dissenting view: One panellist argued that scoring v0 alongside full-stack builders flatters it, and that a fair index would mark it down harder on integrations and backend, not just note the gap. The counter-argument is that v0 is often bought as an alternative to Lovable or Bolt by buyers who do not realise they still need a backend, and pretending it competes only with component libraries would leave those buyers uninformed. Our reviews editor also flagged that the free tier is thin enough to be misleading about real monthly cost. Best for: Teams that already have engineers and an API, and want interface code that matches their existing Next.js conventions. Not for: Non-technical founders who need a database, auth and a deployed product rather than components. Axis scores out of 5: - Reliability: 4.3 - Integrations: 3.8 - SEO and GEO: 4.2 - Design quality: 4.8 - Agent performance: 4.2 - Speed: 4.6 - Value: 3.8 - Scalability: 4.0 - API and MCP access: 3.6 - Code ownership: 4.8 What works: - Output is genuinely idiomatic Next.js that survives code review - Design quality and accessibility defaults are the best in the index - Slots into an existing repository instead of demanding a new one - Fastest iteration loop of anything we tested on pure interface work What does not: - No database, no auth, no backend, so half the product is still yours to build - Credit pricing makes heavy exploration expensive - Strongly assumes the Vercel and Next.js world view - Weak once a screen needs real server-side business logic Capability checks: - Full-stack backend: Partial, route handlers only - Database included: No, bring your own - Auth included: No, bring your own - Code export: Yes, copy or fork - GitHub sync: Yes - One-click deploy: Yes, to Vercel - Custom domain: Yes, via Vercel - Mobile or native output: Responsive web only - Team collaboration: Yes, paid plans - Public API or MCP server: Yes - Self-hosting the output: Yes, standard Next.js Pricing tiers: - Free: Free monthly. Monthly credit allowance, public chats - Plus: USD 30 per user, monthly. Higher credits, private chats, custom domains via Vercel - Team: Not captured per user, monthly. Shared projects, design system sync, SSO on higher tiers Plan exists, price not captured in our 19 and 20 August 2026 check. - Enterprise: On request quote. Volume usage, audit, procurement FAQ: - Q: Is v0 a full app builder? A: No, and it does not claim to be. v0 generates front-end code, primarily Next.js with Tailwind and shadcn/ui. You supply the database, the authentication and the business logic, or you pair it with a backend platform. - Q: How good is the code v0 produces? A: The best in this index. Our panel scored it 4.8 stars on design and it was the only tool whose output went into three production repositories without reformatting. It reads like code a senior front-end developer would have written. - Q: Is v0 cheaper than Lovable? A: No. The entry price is higher, at USD 30 per user per month against USD 25, and the comparison is not like for like. With v0 you are also paying an engineer to build the backend that Lovable includes. - Q: Can v0 output be self-hosted? A: Yes. The result is a standard Next.js project. Deploying to Vercel is the smooth path, but nothing stops you running it anywhere Node runs. ### 5. Retool - 4.1/5 - Slug: retool - Official site: https://retool.com - Category: internal_tools - Price from: EUR 9 / builder / month, billed annually (the vendor's own currency, not converted). Free tier: yes - Price note: Team plan, billed annually, EU price list, plus EUR 5 per internal user. The realistic tier is Business at EUR 46 per builder plus EUR 14 per internal user, because audit logging, permission controls, embedded apps and unlimited environments all start there. A reader anchored on about 10 EUR will be off by an order of magnitude. - Pricing model: Free plan for up to five users. Team from EUR 9 per builder a month billed annually, plus EUR 5 per internal user, and the tier most buyers actually need is Business at EUR 46 per builder plus EUR 14 per internal user. - Star ratings counted: 37, community average 4.2/5 - Written reviews counted: 3 (a different number from the star ratings above) - Last verified: 2026-08-20T00:00:00.000Z - Review: https://www.app-builder-index.com/reviews/retool - Spanish edition: https://www.app-builder-index.com/es/opiniones/retool - Profile: https://www.app-builder-index.com/builders/retool Summary: The default platform for building internal admin panels and operational tools against production databases and APIs, with real version control, permissions and self-hosting. Verdict: The most professionally engineered product in this index, and priced accordingly. Retool takes the top marks on integrations at 4.7 and reliability at 4.6 because it connects to real databases with real credentials, has genuine source control, and self-hosts properly: a full deployment inside your own VPC via Docker in about fifteen minutes, which is a stronger ownership story than any hosted builder here, including our top-ranked tool. It also imports React apps built elsewhere, from Lovable or Replit, by ZIP upload or GitHub sync, and it now promotes a hosted MCP server on its own homepage: "Build an app from your favorite AI coding agent and deploy it here within your governed Retool environment." The honest qualifier on that axis is that the MCP server exists while the Platform API is Enterprise only with no published per-call price. Two costs to plan for: per-user pricing gets expensive fast, and Agents are billed separately from AI credits at a rate the vendor does not publish, so agent-heavy usage cannot be costed from public information. Dissenting view: The editor in chief pushed for a lower design score, arguing Retool output looks like Retool no matter what you do. The panel settled at 3.7 because internal users tend not to care. Best for: Engineering teams building admin panels and operational tooling over production data. Not for: Non-technical solo founders, and anything customer-facing. Axis scores out of 5: - Reliability: 4.6 - Integrations: 4.7 - SEO and GEO: n/a, axis not applicable to this tool - Design quality: 3.7 - Agent performance: 3.6 - Speed: 4.0 - Value: 3.0 - Scalability: 4.5 - API and MCP access: 4.5 - Code ownership: 3.8 What works: - Highest integration score in the index at 4.7, with real database connectors - Full self-hosting inside your own VPC via Docker in about fifteen minutes, which beats every hosted builder here on that specific question - Hosted MCP server for building from your own AI coding agent and deploying inside your governed environment - Imports React apps from Lovable or Replit by ZIP or GitHub sync, so work started elsewhere is not stranded What does not: - Per-user pricing becomes a significant line item quickly - Agents are billed separately from AI credits and the Agent rate is not published, so agent-heavy cost cannot be computed from public information - The Platform API is Enterprise only, with no published per-call price - Assumes SQL and API literacy, so not a no-code tool in practice Capability checks: - Full-stack backend: Yes, connects to yours - Database included: No, bring your own - Auth included: Yes, with SSO and granular permissions - Code export: Partial, apps as JSON in Git, plus React app import from Lovable or Replit by ZIP or GitHub sync - GitHub sync: Yes, source control on paid plans - One-click deploy: Yes, or self-host - Custom domain: Yes, paid plans - Mobile or native output: Retool Mobile - Team collaboration: Yes, with review and staging - Public API or MCP server: Yes, a hosted MCP server for building from an AI coding agent inside your governed environment. The Platform API is Enterprise only, with no published per-call price - Self-hosting the output: Yes, a full self-host inside your own VPC via Docker in about fifteen minutes Pricing tiers: - Free: Free monthly. Up to five users, core features - Team: EUR 9 per builder, monthly, billed annually. Source control, staging, more connectors Plus EUR 5 per internal user. - Business: EUR 46 per builder, monthly. Audit logging, permission controls, embedded apps, unlimited environments Plus EUR 14 per internal user. - Enterprise: On request quote. Procurement, support terms, volume seats FAQ: - Q: Is Retool no-code? A: Not really. You will write SQL and JavaScript expressions. It is a low-code tool for engineers, which is why non-technical buyers usually end up on Glide or Softr instead. - Q: Can Retool be self-hosted? A: Yes, and properly: a full deployment in your own VPC via Docker in about fifteen minutes. That is a large part of why regulated teams choose it, and why it scores 3.8 on code ownership despite not exporting a normal codebase. - Q: Does Retool have an MCP server? A: Yes, a hosted one, promoted on its own homepage: build an app from your favourite AI coding agent and deploy it inside your governed Retool environment. The Platform API, separately, is Enterprise only and carries no published per-call price. - Q: Is Retool worth the per-user price? A: If it replaces engineering time on internal admin work, usually yes. Budget separately for Agents, which are billed apart from AI credits at a rate the vendor does not publish. ### 6. Airtable - 4.0/5 - Slug: airtable - Official site: https://airtable.com - Category: internal_tools - Price from: USD 20 / user / month, billed annually (the vendor's own currency, not converted). Free tier: yes - Price note: Team plan, billed annually. USD 24 billed monthly. Portals guest access is a separate add-on from USD 120 a month for 15 guests. - Pricing model: Free plan with record limits. Team at USD 20 per user a month billed annually, USD 24 monthly, and Portals guest access is a separate add-on from USD 120 a month for 15 guests. - Star ratings counted: 31, community average 4.1/5 - Written reviews counted: 3 (a different number from the star ratings above) - Last verified: 2026-08-20T00:00:00.000Z - Review: https://www.app-builder-index.com/reviews/airtable - Spanish edition: https://www.app-builder-index.com/es/opiniones/airtable - Profile: https://www.app-builder-index.com/builders/airtable Summary: The collaborative database that half the industry already runs on, with Interfaces and an AI layer that turn a base into something close to an internal application. Verdict: Buy it as a database, use the app features as a bonus, and take the agent surface seriously. Airtable is one of the most reliable data layers in this index at 4.5, and its API and MCP score of 4.8 is now the highest on this site, above Totalum's 4.7: an official MCP server, one-click OAuth for Claude and ChatGPT, a Claude Code plugin, an npm CLI, a library of agent skills and a native agent runtime. That is the strongest first-party agent surface on the roster. It is still not an app builder in the sense the rest of this list is: record limits force plan upgrades, per-user pricing adds up, and the SEO and GEO axis does not apply because nothing it builds is a public crawlable page. Guest access is no longer missing, though: Portals is a shipped, priced add-on with custom branding and admin controls over guests. As the backend under Softr or Glide, it is close to unbeatable. Dissenting view: Two panellists thought Airtable should not be in an app builder index at all. It stays because Interfaces are marketed as app building and buyers evaluate it that way. Best for: Teams that need shared operational data first and an interface over it second. Not for: Building an actual product, or anything with public pages. Axis scores out of 5: - Reliability: 4.5 - Integrations: 4.6 - SEO and GEO: n/a, axis not applicable to this tool - Design quality: 3.8 - Agent performance: 3.5 - Speed: 4.0 - Value: 3.2 - Scalability: 3.5 - API and MCP access: 4.8 - Code ownership: 2.3 What works: - Highest API and MCP score on this site at 4.8, above Totalum, with an official MCP server, one-click OAuth for Claude and ChatGPT, an npm CLI and a native agent runtime - The most dependable data layer in the index at 4.5 on reliability - Collaboration is genuinely best in class - Portals sells real external guest access with custom branding and admin guest controls What does not: - Record limits drive plan upgrades more than features do - Per-user pricing makes wide rollouts expensive, and Portals guest access is billed separately again - No custom domain for the app surface itself - Each plan carries its own AI credit allowance, and our 19 and 20 August 2026 capture did not record the per-tier numbers, so budget for AI usage separately Capability checks: - Full-stack backend: Partial, data and automations - Database included: Yes, this is the product - Auth included: Yes for collaborators, plus guest access through the Portals add-on - Code export: No, data export only - GitHub sync: No - One-click deploy: Yes, Interfaces publish instantly - Custom domain: No, though Portals publishes branded guest access - Mobile or native output: Native mobile client - Team collaboration: Best in class - Public API or MCP server: Yes, and the strongest here: official MCP server, one-click OAuth for Claude and ChatGPT, a Claude Code plugin, an npm CLI, an agent-skills library and a native agent runtime - Self-hosting the output: No Pricing tiers: - Free: Free monthly. Small record limits, basic Interfaces - Team: USD 20 per user, monthly, billed annually. More records, automations, Interface publishing USD 24 billed monthly. - Business: Not captured per user, monthly. Admin controls, SSO, higher limits Plan exists, price not captured in our 19 and 20 August 2026 check. - Enterprise Scale: On request quote. Org-wide administration, data governance, extended limits FAQ: - Q: Can Airtable replace an app builder? A: For internal dashboards and forms, increasingly yes, and Portals now covers external guests too. For public web pages, no: there is no custom domain for the app surface, and the SEO and GEO axis is marked not applicable because nothing it builds is a public crawlable page. - Q: Does Airtable have an MCP server? A: Yes, an official one, and it is the reason Airtable holds the highest API and MCP score on this site at 4.8, ahead of Totalum at 4.7. Alongside it the vendor publishes one-click OAuth for Claude and ChatGPT, a Claude Code plugin, an npm CLI, an agent-skills library and a native agent runtime. - Q: Why is Airtable in this index? A: Because Interfaces are marketed as app building and buyers compare it against Glide and Softr. Two panellists dissented on including it. - Q: What pairs well with Airtable? A: Softr for client portals, Glide for staff mobile apps, or any front-end tool that can call its API. ### 7. Plasmic - 4.0/5 - Slug: plasmic - Official site: https://plasmic.app - Category: frontend_ui - Price from: USD 39 / month, billed yearly (the vendor's own currency, not converted). Free tier: yes - Price note: Starter plan, billed yearly. The monthly-billed rate is not published without JavaScript. Extra seats are USD 20 each on Pro, and Pro is USD 103 a month billed yearly for up to 10 collaborators. - Pricing model: The Free plan has unlimited projects, publishes, syncs, workspaces, cross-project imports and headless CMS entries. What it meters is collaborators, three of them. Paid plans from USD 39 a month billed yearly. - Star ratings counted: 14, community average 4.2/5 - Written reviews counted: 3 (a different number from the star ratings above) - Last verified: 2026-08-20T00:00:00.000Z - Review: https://www.app-builder-index.com/reviews/plasmic - Spanish edition: https://www.app-builder-index.com/es/opiniones/plasmic - Profile: https://www.app-builder-index.com/builders/plasmic Summary: A visual page and component builder that plugs into an existing React or Next.js codebase, letting marketing edit pages without a deploy while engineers keep owning the code. Verdict: The best engineering fit of any visual tool here. Plasmic renders into your own React or Next.js app, so pages stay fast and indexable, scoring 4.4 on speed and 4.3 on SEO and GEO, and code ownership at 4.3 is near the top because your repository never stops being yours. The rendering mode on that SEO axis is decided by your host codebase rather than by Plasmic, which is the honest way to read the score. The API mark of 3.2 is the one that needs explaining: the "Extended platform APIs", white labeling and embedding are Enterprise-only features with no published API reference and no published price, so a buyer below Enterprise cannot evaluate the programmable surface at all. Version history is tier limited too, from 14 to 180 days depending on plan. AI features are minor and the initial integration needs a developer for a day. If you have engineers and a marketing team who keep filing page-edit tickets, this pays for itself immediately. Dissenting view: The testing lead argued Plasmic is a CMS rather than an app builder. The panel kept it in because it generates interactive components, not just content. Best for: Product and marketing teams who want visual editing inside a codebase engineers already own. Not for: Anyone without a React codebase or an engineer to wire it in. Axis scores out of 5: - Reliability: 4.2 - Integrations: 4.0 - SEO and GEO: 4.3 - Design quality: 4.2 - Agent performance: 3.0 - Speed: 4.4 - Value: 3.7 - Scalability: 4.1 - API and MCP access: 3.2 - Code ownership: 4.3 What works: - Renders inside your own Next.js app, so speed and SEO stay under your control - Code ownership at 4.3, one of the highest in the index - Marketing can edit pages without asking engineering for a deploy What does not: - Extended platform APIs, white labeling and embedding are Enterprise only, with no published API reference and no published price, which is what the 3.2 API mark reflects - Version history is tier limited, from 14 to 180 days depending on plan - Requires an existing React codebase and a developer to integrate - No backend, database or auth of its own Capability checks: - Full-stack backend: No - Database included: No, connect your own - Auth included: Bring your own - Code export: Yes, generates real components - GitHub sync: Yes, codegen into your repo - One-click deploy: Yes, or ship with your app - Custom domain: Wherever you host - Mobile or native output: Responsive web only - Team collaboration: Yes, with roles - Public API or MCP server: Headless API, yes. Extended platform APIs, white labeling and embedding are Enterprise only, with no published API reference and no published price - Self-hosting the output: Yes, it runs inside your app Pricing tiers: - Free: Free monthly. Unlimited projects, publishes, syncs, workspaces and CMS entries, 3 collaborators - Starter: USD 39 monthly, billed yearly. More collaborators, codegen, custom components - Pro: USD 103 monthly, billed yearly. Up to 10 collaborators, roles, localisation Extra seats USD 20 each. - Scale: USD 399 monthly, billed yearly. 8 to 30 collaborators, content creator mode, A/B testing, scheduled content FAQ: - Q: Is Plasmic a CMS or an app builder? A: Both, arguably. It edits interactive components inside your codebase, which is why we list it, though one panellist dissented. - Q: Does Plasmic hurt page speed? A: No, that is the point. Components render in your own app, giving it 4.4 on speed and 4.3 on SEO and GEO. The rendering mode is determined by your host codebase, not by Plasmic. - Q: Why does the API score only reach 3.2? A: Because the extended platform APIs, white labeling and embedding are Enterprise-only features, published without an API reference and without a price. Below Enterprise there is nothing programmable to evaluate. - Q: Who should not buy Plasmic? A: Anyone without a React codebase. There is nothing for it to plug into. ### 8. Base44 - 4.0/5 - Slug: base44 - Official site: https://base44.com - Category: internal_tools - Price from: USD 16 / month, billed annually (the vendor's own currency, not converted). Free tier: yes - Price note: Starter plan, billed annually. - Pricing model: Free plan with a monthly message allowance. Starter at USD 16 a month billed annually. - Star ratings counted: 63, community average 3.9/5 - Written reviews counted: 5 (a different number from the star ratings above) - Last verified: 2026-08-20T00:00:00.000Z - Review: https://www.app-builder-index.com/reviews/base44 - Spanish edition: https://www.app-builder-index.com/es/opiniones/base44 - Profile: https://www.app-builder-index.com/builders/base44 Summary: An all-in-one builder, now part of Wix, that bundles database, auth, email and hosting behind a single conversational surface with no external services to wire up. Verdict: Buy for internal tools, think hard for anything customer-facing. Base44 is the most forgiving product in this index for someone who has never opened a terminal: there is no Supabase key to paste, no deployment step to understand, no npm. Database, auth, email and hosting are simply there. Two of our non-technical testers completed a working staff rota tool on Base44 and on nothing else. Its entry tier is strong value for a full-stack product. The cost of that simplicity is ownership: the batteries are included because they are bolted in. Dissenting view: The minority view, and it is a strong one, is that we are under-penalising lock-in. Our data editor argued that a 2.8 on code ownership is generous for a platform where the runtime, the database and the auth all belong to the vendor, and that a business putting a core process on Base44 is taking on a migration cost it has not priced. The counter is that internal tools are frequently disposable, and paying for portability you will never use is its own waste. Both positions are in the record because both are defensible. Best for: Operations and business teams building internal tools without engineering support. Not for: Anyone who needs to own and self-host the resulting codebase. Axis scores out of 5: - Reliability: 4.0 - Integrations: 4.1 - SEO and GEO: 3.5 - Design quality: 4.0 - Agent performance: 4.1 - Speed: 4.8 - Value: 4.2 - Scalability: 3.7 - API and MCP access: 3.2 - Code ownership: 2.8 What works: - Genuinely no setup: no external database keys, no deploy step, no npm - The fastest agent we ran at 4.8, and a public benchmark records the same on its own first build prompt - Highest completion rate among our non-technical testers - Strong value at the entry tier for a full-stack product What does not: - Weak code ownership at 2.8, among the lowest here - Thin public API and MCP surface limits automation - Scaling and performance controls are largely out of your hands - SEO defaults are basic, so it is a poor choice for public content Capability checks: - Full-stack backend: Yes, managed - Database included: Yes, built in - Auth included: Yes, built in - Code export: Partial - GitHub sync: Partial - One-click deploy: Yes - Custom domain: Yes, paid plans - Mobile or native output: Responsive web only - Team collaboration: Yes - Public API or MCP server: Limited - Self-hosting the output: No Pricing tiers: - Free: Free monthly. Monthly message allowance, Base44 subdomain - Starter: USD 16 monthly, billed annually. More messages, custom domain, private apps - Builder: USD 40 monthly, billed annually. Higher allowance, collaborators, analytics - Pro: USD 80 monthly, billed annually. 500 message credits a month, 20,000 integration credits, early access to beta features - Elite: USD 160 monthly, billed annually. 1,200 message credits a month, 50,000 integration credits, premium support FAQ: - Q: Is Base44 good for non-technical users? A: It is the best in this index for that. There is nothing to install and nothing to connect. In our panel testing it had the highest completion rate among testers who do not write code. - Q: Can you export your app from Base44? A: Only partially, and this is the main reason to hesitate. The runtime, database and auth are the vendor's. We score it 2.8 on code ownership, among the lowest here. - Q: Base44 or Lovable? A: Base44 if nobody on the team writes code and the app is internal. Lovable if you have a developer, care how it looks, or expect to take the code with you. - Q: Is Base44 still independent? A: No. It was acquired by Wix in 2025 and now sits inside that group. Our reliability score reflects post-acquisition testing. ### 9. Replit - 4.0/5 - Slug: replit - Official site: https://replit.com - Category: full_stack - Price from: USD 18 / month, billed annually (the vendor's own currency, not converted). Free tier: yes - Price note: Core plan, billed annually. USD 20 billed monthly, and agent usage and deployment compute bill separately on top. - Pricing model: Free plan for public projects. Core at USD 20 a month, USD 18 billed annually, with agent usage and deployment compute billed separately. - Star ratings counted: 97, community average 4.1/5 - Written reviews counted: 5 (a different number from the star ratings above) - Last verified: 2026-08-20T00:00:00.000Z - Review: https://www.app-builder-index.com/reviews/replit - Spanish edition: https://www.app-builder-index.com/es/opiniones/replit - Profile: https://www.app-builder-index.com/builders/replit Summary: A browser development environment with an agent on top: full Linux containers, a real shell, managed Postgres and deployments, all in one tab. Verdict: Buy, if your app has a back of house. Replit is the tool in this index where the agent is standing on a real computer: it can run migrations, read logs, install a system package, retry a failing test and tell you what broke. That is why it takes 4.5 on scalability, and why our panel's most complicated build, a scheduled importer with a queue and a webhook receiver, only finished on Replit and Totalum. The trade is time and aesthetics. Speed is 2.9, the lowest in the index, and the public AI Agents Benchmark 2026 records the same thing, titling Replit "The Dynamite Agent" and listing the con "Extremely slow (over 1 hour sometimes)". The default interfaces are plain, and the product assumes you are comfortable seeing a shell. Dissenting view: Our design reviewer dissents firmly. She argues that for the large majority of buyers, who are building a customer-facing app rather than a data pipeline, Replit's output is the weakest-looking in the index and the surrounding IDE is intimidating enough to stall non-technical users on day one. She also notes that compute billing plus agent billing makes the true monthly cost genuinely hard to forecast, and that a builder you cannot budget for is a builder a small company should think twice about. Best for: Technical founders and internal tooling teams whose apps need scripts, cron jobs, queues and a real filesystem. Not for: Buyers who want a beautiful marketing-grade front end generated for them without touching a terminal. Axis scores out of 5: - Reliability: 4.2 - Integrations: 4.4 - SEO and GEO: 3.4 - Design quality: 3.6 - Agent performance: 4.3 - Speed: 2.9 - Value: 3.7 - Scalability: 4.5 - API and MCP access: 4.5 - Code ownership: 4.6 What works: - The agent has a real shell, so it can actually diagnose and fix its own failures - Best scalability story in the index: cron, queues, background workers, migrations - Managed Postgres, object storage and deployments without leaving the tab - Live multiplayer editing is still unmatched for pair debugging What does not: - Slowest tool in the index at 2.9 on speed, a finding a public benchmark records as well - Generated interfaces look plainest of any builder we tested - Compute plus agent billing makes monthly cost hard to predict - The IDE surface intimidates non-technical users Capability checks: - Full-stack backend: Yes, full Linux container - Database included: Yes, managed Postgres - Auth included: Yes, Replit Auth - Code export: Yes, full source - GitHub sync: Yes, two-way - One-click deploy: Yes - Custom domain: Yes, paid plans - Mobile or native output: Responsive web, Expo possible - Team collaboration: Yes, live multiplayer - Public API or MCP server: Yes - Self-hosting the output: Yes, standard code Pricing tiers: - Starter: Free monthly. Public apps, limited agent usage, shared compute - Core: USD 20 monthly. Monthly usage credits, private apps, more compute, deployments USD 18 billed annually. - Pro: USD 100 monthly. Up to 15 collaborators, 10 parallel agents, database rollback up to 28 days USD 90 billed annually. - Enterprise: On request quote. SSO, audit logs, procurement, support terms FAQ: - Q: Is Replit good for non-developers in 2026? A: Less than its rivals. The agent will build you an app, but the moment something breaks you are looking at a shell and a stack trace. Non-technical buyers finish more projects on Lovable or Base44. - Q: Can Replit run background jobs and cron? A: Yes, and this is the main reason to choose it. It is a real Linux container, so scheduled jobs, workers and long-running processes work the way they do on a server, which is not true of most builders in this index. - Q: How much does Replit actually cost per month? A: Core is USD 20 a month, USD 18 billed annually, but agent usage and deployment compute bill separately. Our panel's medium-complexity project ran at roughly two to three times the plan price, depending on how much the agent was used. - Q: Do you keep the code? A: Yes. Projects sync to GitHub and the source is ordinary code with no proprietary runtime, so you can move it to your own infrastructure. ### 10. FlutterFlow - 3.9/5 - Slug: flutterflow - Official site: https://flutterflow.io - Category: mobile - Price from: USD 39 / month, billed monthly (the vendor's own currency, not converted). Free tier: yes - Price note: Basic plan. Seat pricing is tiered above that: Growth is USD 80 for the first seat and USD 55 for the second, Business is USD 150 for the first seat and USD 85 for seats 2 to 5. - Pricing model: Free plan to build and preview. Paid plans are Basic at USD 39 a month, then Growth and Business, which price the first seat higher than the ones after it. Enterprise and Education are quoted separately. - Star ratings counted: 34, community average 4.3/5 - Written reviews counted: 3 (a different number from the star ratings above) - Last verified: 2026-08-20T00:00:00.000Z - Review: https://www.app-builder-index.com/reviews/flutterflow - Spanish edition: https://www.app-builder-index.com/es/opiniones/flutterflow - Profile: https://www.app-builder-index.com/builders/flutterflow Summary: A visual builder that generates real Flutter projects for iOS, Android and web, with Firebase or Supabase behind it and full source export on paid plans. Verdict: The best mobile tool in this index, and one of the strongest agent stories on the roster. FlutterFlow generates genuine Flutter projects, exports the source on paid plans, and produces interfaces that look designed rather than generated, taking 4.3 on both design and integrations. It also ships an official documented MCP server plus a CLI that lets Claude Code, Gemini CLI or Codex create and edit real projects, which is why the API and MCP axis sits at 4.3 rather than among its weaknesses. Disclose the gates before you budget: CLI access is a Business-tier feature at USD 150 for the first seat, GitHub Integration starts at Growth rather than at the entry tier, so a repository workflow costs about twice the headline price, and AI generation on the Free tier is 5 requests per lifetime, not per month. The vendor builds "Mobile, Web, & Desktop Apps" and ships a Local Run Desktop Emulator, so desktop belongs in its coverage alongside iOS, Android and web. The catch is that you inherit Flutter: web output is heavy and scores 2.8 on SEO, and debugging eventually means reading Dart. Dissenting view: The Spanish edition editor argued the learning curve is understated for non-developers, who often stall the first time a widget tree needs restructuring by hand. Best for: Teams that need one codebase for iOS, Android and web with a real exit path to Flutter source. Not for: Anyone who needs a fast public website, or who has never met a widget tree. Axis scores out of 5: - Reliability: 4.3 - Integrations: 4.3 - SEO and GEO: 2.8 - Design quality: 4.3 - Agent performance: 3.5 - Speed: 4.1 - Value: 3.6 - Scalability: 4.2 - API and MCP access: 4.3 - Code ownership: 4.4 What works: - Official documented MCP server plus a CLI that lets Claude Code, Gemini CLI or Codex create and edit real projects - Full Flutter source export at the entry paid tier, giving 4.4 on code ownership - One codebase genuinely covers iOS, Android, web and desktop, with a Local Run Desktop Emulator - One-click App Store deployment is included in the Basic plan, the entry paid tier What does not: - CLI access is a Business-tier feature at USD 150 for the first seat, so the strongest agent workflow is the most expensive one - GitHub Integration starts at Growth, not at the entry tier, which roughly doubles the cost of a repository workflow - AI generation on the Free tier is 5 requests per lifetime, not per month - Web builds are heavy, which puts SEO at 2.8, and real debugging eventually requires reading Dart Capability checks: - Full-stack backend: Yes, via Firebase or Supabase - Database included: Yes, through Firebase or Supabase - Auth included: Yes - Code export: Yes, full Flutter source on paid plans - GitHub sync: Yes, from the Growth plan rather than the entry tier - One-click deploy: Yes, one-click App Store deployment is listed in the Basic plan, plus web builds - Custom domain: Yes, for web output - Mobile or native output: Native iOS and Android from Flutter, plus web and desktop, with a Local Run Desktop Emulator - Team collaboration: Yes, with real-time editing - Public API or MCP server: Yes, an official documented MCP server, plus a CLI for Claude Code, Gemini CLI or Codex that is a Business-tier feature at USD 150 for the first seat - Self-hosting the output: Yes, after source export Pricing tiers: - Free: Free monthly. Build and preview, FlutterFlow branding - Basic: USD 39 monthly. Code export, custom domain, GitHub integration - Growth: USD 80 first seat, monthly. Store deployment, custom code, more integrations USD 80 first seat, USD 55 second seat. - Business: USD 150 first seat, monthly. Shared projects, design system, roles USD 150 first seat, USD 85 for seats 2 to 5. - Enterprise: On request quote. Procurement, security review, volume seats - Education: On request quote. Classroom and institution licensing FAQ: - Q: Does FlutterFlow give you the source code? A: Yes, full Flutter source on paid plans from USD 39, which is why it scores 4.4 on code ownership. GitHub Integration, separately, starts at Growth. - Q: Can I drive FlutterFlow from an AI agent? A: Yes. It publishes an official documented MCP server, and a CLI that lets Claude Code, Gemini CLI or Codex create and edit real projects. The CLI is a Business-tier feature at USD 150 for the first seat. - Q: Do I need a higher plan to publish to the App Store? A: No. One-click App Store deployment is listed in the Basic plan card, the entry paid tier. What sits higher is the repository workflow, since GitHub Integration starts at Growth. - Q: Is FlutterFlow good for websites? A: Not really. Flutter web output is heavy and hard to index, giving it 2.8 on SEO and GEO. Use it for apps across mobile, web and desktop. ### 11. WeWeb - 3.9/5 - Slug: weweb - Official site: https://weweb.io - Category: frontend_ui - Price from: USD 20 / month, billed monthly (the vendor's own currency, not converted). Free tier: yes - Price note: Essential plan, which is the editor only. The free plan can publish up to 1,000 sessions on a WeWeb subdomain. Publishing on a custom domain with a database needs Essential USD 20 plus Launch+ USD 20, so about USD 40 a month. - Pricing model: The free plan can publish, up to 1,000 sessions on a WeWeb subdomain. The editor starts at USD 20 a month, and publishing on a custom domain with a database adds Launch+ at USD 20, so about USD 40. - Star ratings counted: 17, community average 4.4/5 - Written reviews counted: 3 (a different number from the star ratings above) - Last verified: 2026-08-20T00:00:00.000Z - Review: https://www.app-builder-index.com/reviews/weweb - Spanish edition: https://www.app-builder-index.com/es/opiniones/weweb - Profile: https://www.app-builder-index.com/builders/weweb Summary: A visual web app front-end builder that connects to your own database or backend service, exports clean Vue and is aimed at agencies delivering production work. Verdict: The professional choice in this bracket, with one caveat that moved its score. WeWeb takes 4.4 on integrations because it treats a web application as something that has to be connected to real data, and WeWeb Cloud now ships a real managed backend of its own: a managed database, lambda compute, file storage and transactional email, which is why we have changed its category rather than calling it a pure front-end tool. SEO is the loss, at 3.1. The output is a Vue.js single-page application, and the vendor's own cheapest hosting tier is named "Static sites and SPAs", so unless the customer adds a rendering layer of their own, crawlers and LLM fetchers get an empty shell. Two commercial facts matter more than the sticker price. WeWeb does not charge per app user on any tier, and end users, APIs and workflows are unlimited everywhere, which is a decisive advantage over Softr and Retool as an audience grows. Against that, MCP is effectively a Pro feature at USD 50 a month per developer, with a 14-day trial on Free and no listing on Essential, and the Free tier cannot export code, so ownership, the platform's headline promise, is paywalled. Dissenting view: One panellist wanted a higher value score, noting agencies bill the build anyway. The mark accounts for the fact that a working product needs a second paid tool underneath. Best for: Agencies and product teams building a real front end over Xano, Supabase or an existing API. Not for: Solo founders who want the backend built for them from a prompt. Axis scores out of 5: - Reliability: 4.3 - Integrations: 4.4 - SEO and GEO: 3.1 - Design quality: 4.1 - Agent performance: 3.2 - Speed: 4.2 - Value: 3.8 - Scalability: 4.0 - API and MCP access: 4.2 - Code ownership: 3.5 What works: - No per-app-user charge on any tier, with end users, APIs and workflows unlimited everywhere, which beats Softr and Retool as the audience grows - Connects cleanly to any REST or GraphQL backend, at 4.4 on integrations - WeWeb Cloud adds a managed database, lambda compute, file storage and transactional email if you do not want a second vendor What does not: - Output is a Vue.js single-page application, and the vendor's own cheapest hosting tier is named Static sites and SPAs, so crawlers and LLM fetchers get an empty shell unless you add your own rendering layer. SEO and GEO is 3.1 - MCP is effectively a Pro feature at USD 50 a month per developer, with a 14-day trial on Free and no listing on Essential - The Free tier cannot export code, so ownership, the headline promise, is paywalled - Learning curve assumes you understand data binding and collections Capability checks: - Full-stack backend: Optional, WeWeb Cloud ships a managed database, lambda compute, file storage and transactional email, or connect your own - Database included: Optional, WeWeb Cloud managed database, or bring Xano, Supabase or an API - Auth included: Yes, via your provider - Code export: Yes, Vue export on higher plans. The Free tier cannot export - GitHub sync: Limited - One-click deploy: Yes, or self-host the export - Custom domain: Yes, paid plans - Mobile or native output: Responsive web and PWA - Team collaboration: Yes - Public API or MCP server: Connects to any REST or GraphQL source. MCP is effectively a Pro feature at USD 50 a month per developer, with a 14-day trial on Free and no listing on Essential - Self-hosting the output: Yes, with code export Pricing tiers: - Free: Free monthly. Build and publish on a WeWeb subdomain, up to 1,000 sessions No code export on this tier. - Essential: USD 20 monthly. One editor seat Editor only, publishing is a separate plan. - Launch+: USD 20 monthly. Publishing, custom domain, database - Scale: Not captured monthly. More projects, code export, team seats Plan exists, price not captured in our 19 and 20 August 2026 check. FAQ: - Q: Does WeWeb include a database? A: Optionally, yes. WeWeb Cloud ships a managed database, lambda compute, file storage and transactional email. You can still bring Xano, Supabase or your own API instead. - Q: Is WeWeb good for SEO? A: Less than we used to say, which is why the axis is 3.1. The output is a Vue.js single-page application, and the vendor's own cheapest hosting tier is named "Static sites and SPAs". Client-rendered output means crawlers and LLM fetchers receive an empty shell unless you add a rendering layer yourself. - Q: Can you export code from WeWeb? A: Vue export is available on higher plans, which is why code ownership scores 3.5. The Free tier cannot export at all, so the ownership promise is paywalled. - Q: Does WeWeb charge per app user? A: No, on any tier. End users, APIs and workflows are unlimited on every plan, which is a decisive commercial difference from Softr and Retool. ### 12. Xano - 3.9/5 - Slug: xano - Official site: https://xano.com - Category: full_stack - Price from: USD 85 / month, billed annually (the vendor's own currency, not converted). Free tier: yes - Price note: Essential plan, billed annually. - Pricing model: Free plan on shared resources. Essential at USD 85 a month billed annually. - Star ratings counted: 21, community average 4.3/5 - Written reviews counted: 3 (a different number from the star ratings above) - Last verified: 2026-08-20T00:00:00.000Z - Review: https://www.app-builder-index.com/reviews/xano - Spanish edition: https://www.app-builder-index.com/es/opiniones/xano - Profile: https://www.app-builder-index.com/builders/xano Summary: A visual backend platform that gives you a real Postgres database, a REST API you design without writing code, and background tasks, intended to sit under whatever front end you like. Verdict: The most useful half-a-product in the index, and it is a backend platform rather than a full-stack builder: the vendor's own second section is "Connect to any frontend", naming Lovable, WeWeb, Bubble, Bolt, FlutterFlow, Webflow and Replit. Xano gives you a genuine PostgreSQL database with direct database access, triggers and Redis caching, a designed REST API and background jobs, all built visually, which is why it takes 4.6 on API and MCP and 4.4 on scalability. On the database specifically it beats every all-in-one here, including our top-ranked tool: Totalum runs on Cloudflare D1, which is SQLite compatible and not PostgreSQL. The agent surface is deeper than we previously published: a native MCP server the vendor describes as "expose every API as a governed AI tool", plus an MCP Builder, an Agent Builder and a developer CLI MCP, with the no-code MCP and agent builder available on the free tier. Two free-tier limits decide whether you can evaluate it at all: a hard rate limit of 10 requests per 20 seconds, and US-only hosting, so an EU buyer cannot test in region without paying. It has no front end whatsoever, so design scores 3.0 and that is fair. Dissenting view: One panellist argued a backend-only tool cannot fairly carry a design score at all. The published methodology applies every axis to every entry, so the mark stands with the dissent recorded. Best for: Teams pairing a no-code or generated front end with a backend that will survive real traffic. Not for: Anyone looking for a complete application from one prompt. Axis scores out of 5: - Reliability: 4.5 - Integrations: 4.3 - SEO and GEO: n/a, axis not applicable to this tool - Design quality: 3.0 - Agent performance: 3.4 - Speed: 4.2 - Value: 3.2 - Scalability: 4.4 - API and MCP access: 4.6 - Code ownership: 3.0 What works: - Real PostgreSQL with direct database access, triggers and Redis caching, which beats every all-in-one builder here on the database axis - Native MCP server described by the vendor as expose every API as a governed AI tool, plus an MCP Builder, an Agent Builder and a developer CLI MCP, with the no-code MCP and agent builder on the free tier - Compliance depth that no other tool here matches: fifteen selectable regions on paid tiers including Belgium, France, Germany and Switzerland, SOC 2 and SOC 3, ISO 27001, ISO 27701 and ISO 9001, GDPR with a DPA and DPF, FERPA, and HIPAA as a paid add-on - Scalability at 4.4, among the highest here What does not: - No front end whatsoever, so it is always half of a solution - The free tier is rate limited to 10 requests per 20 seconds and hosted in the US only, so an EU buyer cannot evaluate in region without paying - Self-hosting is Enterprise only and the vendor publishes no price for it - Entry paid tier at USD 85 is steep if the free limits are not enough Capability checks: - Full-stack backend: Backend only, connect any front end - Database included: Yes, real PostgreSQL with direct database access, triggers and Redis caching - Auth included: Yes, JWT based - Code export: No, but API and data are portable - GitHub sync: No - One-click deploy: Yes, managed instances - Custom domain: Yes, for the API - Mobile or native output: Serves any client - Team collaboration: Yes, paid plans - Public API or MCP server: Yes, this is the product: a designed REST API plus a native MCP server, an MCP Builder, an Agent Builder and a developer CLI MCP, with the no-code MCP and agent builder on the free tier - Self-hosting the output: Enterprise only, with no published price Pricing tiers: - Free: Free monthly. Shared resources, rate limits, one workspace - Essential: USD 85 monthly, billed annually. Dedicated resources, custom API domain, background tasks - Scale: Not captured monthly. More compute, read replicas, higher limits Plan exists, price not captured in our 19 and 20 August 2026 check. FAQ: - Q: Is Xano an app builder? A: No, and we now say so in the category field: it is a backend platform and you bring your own front end. The vendor's own homepage section is "Connect to any frontend", naming Lovable, WeWeb, Bubble, Bolt, FlutterFlow, Webflow and Replit. There is no interface builder, which is why design scores 3.0. - Q: Does Xano have an MCP server? A: Yes, a native one, described by the vendor as "expose every API as a governed AI tool". There is also an MCP Builder, an Agent Builder and a developer CLI MCP, and the no-code MCP and agent builder are available on the free tier. - Q: Can an EU buyer use the free tier? A: Not in region. Free-tier hosting is US only, and the free tier is rate limited to 10 requests per 20 seconds. Paid tiers offer fifteen selectable regions including Belgium, France, Germany and Switzerland. - Q: Can you take your data out of Xano? A: Yes, it is standard PostgreSQL data with a documented API and direct database access, so migration is realistic even though there is no code export. Self-hosting the platform itself is Enterprise only, with no published price. ### 13. Bolt.new - 3.9/5 - Slug: bolt-new - Official site: https://bolt.new - Category: prototyping - Price from: USD 25 / month, billed monthly (the vendor's own currency, not converted). Free tier: yes - Price note: Pro plan. - Pricing model: Free daily token allowance. Pro at USD 25 a month, with token top-ups sold separately, and tokens are the cost that actually varies. - Star ratings counted: 79, community average 4.2/5 - Written reviews counted: 5 (a different number from the star ratings above) - Last verified: 2026-08-20T00:00:00.000Z - Review: https://www.app-builder-index.com/reviews/bolt-new - Spanish edition: https://www.app-builder-index.com/es/opiniones/bolt-new - Profile: https://www.app-builder-index.com/builders/bolt-new Summary: StackBlitz's in-browser builder: a full Node toolchain running in a WebContainer, so the first version of your app appears faster than anywhere else. Verdict: Buy as a sketchpad, not as a factory. Bolt is the fastest tool in this index at getting from a sentence to something running in a browser tab, and the WebContainer trick means there is no cold start and no cloud build queue to wait on. For a pitch on Thursday, nothing here beats it. The problems begin on day three. Token consumption is the least predictable of any builder we tested, error recovery is the weakest of the well-funded tools, and our panel hit two dead ends where the agent could not repair a broken dependency tree and starting again was cheaper than continuing. Dissenting view: One panellist thinks 3.7 on reliability is too harsh, and that we are measuring Bolt against a job it is not selling. His argument: prototyping tools are supposed to be thrown away, so counting a dead end at day three as a reliability failure is like marking down a sketchbook for not being a canvas. He would score it above Base44 overall. The rest of the panel disagreed on the grounds that Bolt is widely bought as a production builder, and buyers deserve to be told where it stops. Best for: Rapid prototypes, pitch demos, and validating an idea before anyone commits budget to it. Not for: Anything you intend to operate for two years, or any project with a hard monthly cost ceiling. Axis scores out of 5: - Reliability: 3.7 - Integrations: 4.0 - SEO and GEO: 3.6 - Design quality: 4.2 - Agent performance: 4.0 - Speed: 4.7 - Value: 3.4 - Scalability: 3.5 - API and MCP access: 3.4 - Code ownership: 4.7 What works: - Fastest path from prompt to running app of anything we tested - No cold start: the toolchain runs in the browser - Full code download or GitHub push, no proprietary runtime - Expo support means a mobile target is genuinely available What does not: - Token burn is the least predictable in the index - Weak recovery when a dependency tree or build breaks - Backend depends on you wiring up Supabase yourself - Long projects accumulate problems the agent cannot unwind Capability checks: - Full-stack backend: Partial - Database included: Via Supabase integration - Auth included: Via Supabase integration - Code export: Yes, download or push - GitHub sync: Yes - One-click deploy: Yes, via Netlify - Custom domain: Yes, via host - Mobile or native output: Expo support - Team collaboration: Limited - Public API or MCP server: Limited - Self-hosting the output: Yes, standard code Pricing tiers: - Free: Free daily. Daily token allowance, public projects - Pro: USD 25 monthly. Monthly token pool, private projects - Teams: USD 30 per member, monthly. Centralised billing, team access management, granular admin controls - Enterprise: On request quote. Advanced security, SSO, audit logs, dedicated account manager FAQ: - Q: Is Bolt.new good enough for production? A: For a small, simple app, sometimes. For anything you plan to operate for years, our panel would not recommend it as the primary builder. Its reliability score of 3.7 reflects two dead ends in our own test builds. - Q: Why is Bolt so fast? A: It runs the Node toolchain inside your browser using StackBlitz WebContainers, so there is no remote build queue and no container to spin up. That is a real engineering advantage and it shows. - Q: How much does Bolt cost in practice? A: Plans start at USD 25 a month but tokens are the real currency. Our testers routinely doubled the base plan with top-ups during a week of active building. - Q: Bolt or Lovable? A: Bolt for the first two days, Lovable for the next two weeks. Bolt is faster to a demo; Lovable is markedly better at surviving iteration. ### 14. Nordcraft - 3.9/5 - Slug: nordcraft - Official site: https://nordcraft.com - Category: frontend_ui - Price from: USD 9 / project / month, billed monthly (the vendor's own currency, not converted). Free tier: yes - Price note: Pro plan, priced per project. Extra custom domains are USD 5 a month each, and AI credits are not included in any plan: they are separate packs at USD 10, 25 and 100. - Pricing model: Open source and free to self-host. Hosted plans are priced per project from USD 9 a month, with extra custom domains at USD 5 each and AI credits sold separately in packs. - Star ratings counted: 4, community average 4.5/5 - Written reviews counted: 2 (a different number from the star ratings above) - Last verified: 2026-08-20T00:00:00.000Z - Review: https://www.app-builder-index.com/reviews/nordcraft - Spanish edition: https://www.app-builder-index.com/es/opiniones/nordcraft - Profile: https://www.app-builder-index.com/builders/nordcraft Summary: The open-source successor to Toddle, a visual web application builder that emits standards-based output, runs without a heavy client runtime and can be self-hosted. Verdict: The most principled tool in the index and one of the smallest. Nordcraft is open source, self-hostable, and produces output with almost no client runtime, which is why it takes 4.6 on speed and 4.4 on SEO and GEO, both near the top. Code ownership is 3.4 rather than the near-perfect mark that "open source" implies, and the reason is what comes out: the export is web components, exported HTML, CSS and JavaScript, not a maintainable source project you would hand to a developer. Two more things a buyer should know before starting: AI credits are not included in any plan, and projects are public by default, which matters if the work is for a client. The trade elsewhere is community size and AI capability, with the assistant at 2.9, among the weakest in the index, and documentation that assumes web platform knowledge. Dissenting view: One panellist argued the reliability mark is generous given how small the maintainer team is, and that a single-vendor open-source project carries a different risk profile than the score implies. Best for: Developers who want visual building without accepting a proprietary runtime or lock-in. Not for: Non-technical buyers, and anyone who needs a large community to lean on. Axis scores out of 5: - Reliability: 3.8 - Integrations: 3.6 - SEO and GEO: 4.4 - Design quality: 3.9 - Agent performance: 2.9 - Speed: 4.6 - Value: 4.5 - Scalability: 3.7 - API and MCP access: 3.9 - Code ownership: 3.4 What works: - Fast published output at 4.6, behind only Base44 and Bolt.new in the index, with almost no client runtime - Open source and self-hostable, so platform lock-in is close to zero - Best value in the second cohort if you are technical enough to use it, at 4.5 What does not: - The export is web components, exported HTML, CSS and JavaScript rather than a maintainable source project, which is why code ownership is 3.4 rather than higher - AI credits are not included in any plan - Projects are public by default, which matters for client work - Among the weakest AI assistance in the index at 2.9, with a small community and thin documentation Capability checks: - Full-stack backend: Partial, server functions - Database included: No, connect your own - Auth included: Bring your own - Code export: Yes, web components: exported HTML, CSS and JavaScript rather than a maintainable source project - GitHub sync: Yes - One-click deploy: Yes, hosted or your own infrastructure - Custom domain: Yes - Mobile or native output: Responsive web only - Team collaboration: Yes - Public API or MCP server: Yes, REST and GraphQL sources - Self-hosting the output: Yes, fully supported, the platform is open source Pricing tiers: - Self-hosted: Free monthly. Open source, run it yourself, no limits - Pro: USD 9 per project, monthly. Managed hosting, custom domain, one project Extra custom domains USD 5 a month each. - Enterprise: On request quote. 99.99% SLA, priority support, custom billing and invoicing FAQ: - Q: Is Nordcraft really open source? A: Yes, the builder and runtime are open source and you can self-host the whole thing. Code ownership still scores 3.4 rather than higher, because what you export is web components, HTML, CSS and JavaScript, not a maintainable source project. - Q: Are AI credits included? A: No, on any plan. Budget for them separately if you intend to use the assistant, which scores 2.9 in any case. - Q: Are Nordcraft projects private? A: Not by default. Projects are public unless you change that, which is worth knowing before you start client work in it. - Q: What happened to Toddle? A: Nordcraft is its successor and rebrand, with the same core approach of standards-based output and no heavy runtime. ### 15. Glide - 3.8/5 - Slug: glide - Official site: https://glideapps.com - Category: internal_tools - Price from: USD 25 / month, billed monthly (the vendor's own currency, not converted). Free tier: yes - Price note: GlideOS Basic plan. Plus is USD 50 a month, Pro is USD 125 a month, and Enterprise is quote based. GlideOS is a separate subscription from Glide Classic and is not accessible through it. - Pricing model: GlideOS sells a Free plan with limited credits, then Basic at USD 25 a month, Plus at USD 50 a month, Pro at USD 125 a month and a quote-based Enterprise tier. Credits are the metered unit, and the published app allowance runs 0, 2, 5 and then unlimited. - Star ratings counted: 23, community average 4.2/5 - Written reviews counted: 3 (a different number from the star ratings above) - Last verified: 2026-09-06T00:00:00.000Z - Review: https://www.app-builder-index.com/reviews/glide - Spanish edition: https://www.app-builder-index.com/es/opiniones/glide - Profile: https://www.app-builder-index.com/builders/glide Summary: GlideOS turns a data source into a polished mobile-shaped internal app in an afternoon, with an AI layer for the parts that would otherwise need a formula. It is a separate product from Glide Classic, on separate plans. Verdict: This review is of GlideOS, the product sold at glideapps.com/pricing today, and that distinction matters more than it sounds. The vendor's own FAQ says GlideOS "is a standalone product, completely separate from the original Glide platform (Glide Classic)", with "its own plans and pricing", requiring "a separate subscription", and "not accessible through the Glide Classic platform". Glide Classic still exists on its own separate plans, which we have not captured as of 20 August 2026, so if you are already running a Classic app, nothing on this page describes your bill. GlideOS itself is very good at a specific and common job: it takes operational mess and produces a fast, good-looking app your warehouse staff will actually use, more reliably than most of the index at 4.3. Note how it meters, because it is not what we used to publish: storage, projects and credits, not rows. Rows were a Glide Classic concept. The API needs the same care: the Glide Tables API works only with built-in Glide Tables and Big Tables, and the vendor excludes external sources such as Google Sheets, Airtable, SQL and Excel, so the data source is the real gate rather than the plan tier. Since connecting an existing spreadsheet is the archetypal Glide use case, that matters. There is no MCP server. There is no code export either. Judge it as an internal tools platform, on the SEO and GEO axis marked not applicable because nothing it builds is a public crawlable page, and it is a genuine buy. Dissenting view: Two panellists argued that reviewing GlideOS while Glide Classic remains on sale gives buyers half a picture, and that we should either capture Classic's plans or say plainly that we have not. The second is what this page now does. Best for: Field teams, inspections, inventory and any internal process currently living in a shared spreadsheet. Not for: Public-facing products, anything that needs to rank in search, or anything you might want to export. Axis scores out of 5: - Reliability: 4.3 - Integrations: 4.0 - SEO and GEO: n/a, axis not applicable to this tool - Design quality: 4.2 - Agent performance: 3.4 - Speed: 4.1 - Value: 3.5 - Scalability: 3.2 - API and MCP access: 3.0 - Code ownership: 2.0 What works: - Reliability at 4.3 is among the best in the index - Row owners give you real per-user data isolation without writing rules - Output feels like a native app on a phone, which drives actual staff adoption What does not: - The Glide Tables API covers built-in Glide Tables and Big Tables only, and excludes Google Sheets, Airtable, SQL and Excel, which is the archetypal Glide data source. There is no MCP server - GlideOS is a separate product and subscription from Glide Classic, which is still sold on separate plans we have not captured - No code export at all, and code ownership of 2.0 to match - Metering is on storage, projects and credits, so growth arrives as several bills rather than one Capability checks: - Full-stack backend: No, app layer over a data source - Database included: Glide Tables and Big Tables, or connect Google Sheets, Excel, Airtable and SQL as external sources - Auth included: Yes, with row owners - Code export: No - GitHub sync: No - One-click deploy: Yes - Custom domain: Yes, paid plans - Mobile or native output: PWA, installable on phones - Team collaboration: Yes - Public API or MCP server: Glide Tables API, and only for built-in Glide Tables and Big Tables. External sources such as Google Sheets, Airtable, SQL and Excel are excluded, and there is no MCP server - Self-hosting the output: No Pricing tiers: - Free: Free monthly. Limited credits, 10 projects, 2 team members, no published apps - Basic: USD 25 monthly. Credits from 100, 10 projects, 2 team members, 2 published apps - Plus: USD 50 monthly. Credits from 250, 20 projects, 3 team members, 5 published apps - Pro: USD 125 monthly. Credits from 250 plus 50 per member, 100 projects, from 5 team members, unlimited published apps - Enterprise: On request quote. Org controls, procurement, support terms FAQ: - Q: Is this review about GlideOS or Glide Classic? A: GlideOS, the product on glideapps.com/pricing as of 20 August 2026. The vendor states that GlideOS is a standalone product, completely separate from Glide Classic, with its own plans and pricing, requiring a separate subscription, and not accessible through the Glide Classic platform. Glide Classic still exists on separate plans, which we have not captured. - Q: What does GlideOS actually meter? A: Storage, projects and credits. Row limits were a Glide Classic concept and do not describe GlideOS pricing. - Q: Does the Glide API work with my Google Sheet? A: No. The Glide Tables API works with built-in Glide Tables and Big Tables only. The vendor excludes external sources including Google Sheets, Airtable, SQL and Excel, so your data source decides whether the API is available to you, not your plan. There is no MCP server. - Q: Glide or Retool? A: Glide if the users are non-technical staff on phones and you have no engineers. Retool if you have engineers and the tool needs to touch production systems. ### 16.

Verdict: Judge it as a design tool and it is very good. Readdy scored 4.6 on design, the third-highest mark in this index, and the markup it emits is genuinely clean, which is why it also takes 4.0 on SEO and GEO without any tuning. It is not an app builder. There is no database, no auth and no server, so a form goes nowhere until you wire it up somewhere else. Pair it with a real backend, or with a developer, and it earns its price. Buy it expecting an application and you will be annoyed within an hour. Dissenting view: The data editor argued that tools with no backend should be scored on a separate scale entirely rather than carrying near-bottom marks on scalability and integrations for a job they never claimed to do. The methodology stands, with the objection recorded here. Best for: Marketing pages, landing pages and front-end work that has to look designed rather than generated. Not for: Anyone expecting a database, accounts or any server-side behaviour. Axis scores out of 5: - Reliability: 4.0 - Integrations: 2.8 - SEO and GEO: 4.0 - Design quality: 4.6 - Agent performance: 3.8 - Speed: 4.5 - Value: 4.2 - Scalability: 2.9 - API and MCP access: 2.6 - Code ownership: 4.1 What works: - Design quality at 4.6 is third in the index, behind v0 and Lovable - Exported markup is clean enough to hand to a front-end engineer without apology - Strong on-page SEO defaults with no configuration - Cheap relative to what it produces What does not: - No backend of any kind, so forms and accounts need another tool - Integration and API scores are near the bottom of the index - Not suitable for anything with a data model - Free tier watermarks the export, which makes it useless for client work Capability checks: - Full-stack backend: No - Database included: No - Auth included: No - Code export: Yes, React or plain HTML - GitHub sync: One-way push - One-click deploy: Yes, static hosting - Custom domain: Yes, paid plans - Mobile or native output: Responsive web only - Team collaboration: Yes, paid plans - Public API or MCP server: No - Self-hosting the output: Yes, static output Pricing tiers: - Free: Free monthly. Limited generations, watermarked export - Starter: USD 25 monthly. Clean export, custom domain, no watermark USD 15 billed annually. - Pro: Not captured monthly. Team seats, higher limits, design system import Plan exists, price not captured in our 19 and 20 August 2026 check. FAQ: - Q: Is Readdy an app builder? A: No. It is a front-end and page generator. It produces interfaces and exportable code, not databases, accounts or server logic. - Q: What do you pair Readdy with? A: A backend service such as Xano or Supabase, or an existing API. Several of our panel use it for the front end and Totalum or Xano for the data layer. - Q: Can you export Readdy code? A: Yes, as React components or plain HTML and CSS. Code ownership scores 4.1, high for this category. - Q: Is Readdy good for SEO? A: Yes, unusually so. Clean semantic markup and fast static output give it 4.0 on our SEO and GEO axis. ### 17. Softr - 3.8/5 - Slug: softr - Official site: https://softr.io - Category: internal_tools - Price from: USD 19 / month, billed monthly (the vendor's own currency, not converted). Free tier: yes - Price note: Basic plan. - Pricing model: Apps, databases, workflows and forms are unlimited on every tier including Free. What Free limits is builders (3), app users (5), database records (5K) and workflow actions (500 a month). Paid plans from USD 19 a month. - Star ratings counted: 26, community average 4.0/5 - Written reviews counted: 3 (a different number from the star ratings above) - Last verified: 2026-08-20T00:00:00.000Z - Review: https://www.app-builder-index.com/reviews/softr - Spanish edition: https://www.app-builder-index.com/es/opiniones/softr - Profile: https://www.app-builder-index.com/builders/softr Summary: Builds client portals, directories and internal tools on top of Airtable, Google Sheets or its own tables, with permissions and gated pages set up in an afternoon. Verdict: Excellent at one job and honest about it. If your data is already in Airtable and you need a gated portal your clients can log into, Softr gets you there faster than anything else in the index, with permissions that behave. It is also more programmable than we previously published: a REST API and an MCP server are available from the entry paid tier, with the vendor's own caveat that certain endpoints may be limited to higher plans. The commercial shape is the thing to understand before you commit. Softr meters two seat axes at once, builders and app users, on top of record and action caps, so a portal gets more expensive precisely as its audience grows. And there is no code export at all: no source to take away and no migration path off the platform, which is why code ownership sits at 2.1. AI credits are 5 a month on Free and 10 on Basic, which makes the AI co-builder a demo rather than a working method at those tiers. Rent it for a portal. Do not build a product on it. Dissenting view: One panellist argued the value score is too low given how much consulting work a Softr portal displaces. The majority held the mark because the free plan stops at three builders, five app users and 5K records, so a real deployment is on a paid tier immediately. Best for: Client portals, membership directories and internal views over data that already lives in Airtable. Not for: Products with their own data model, or anything that has to scale past a few thousand active users. Axis scores out of 5: - Reliability: 4.1 - Integrations: 4.2 - SEO and GEO: n/a, axis not applicable to this tool - Design quality: 3.9 - Agent performance: 3.2 - Speed: 3.7 - Value: 3.9 - Scalability: 3.1 - API and MCP access: 3.9 - Code ownership: 2.1 What works: - Fastest route from an existing Airtable base to a logged-in client portal - REST API and an MCP server from the entry paid tier, with some endpoints limited to higher plans - User groups and gated pages work correctly without configuration archaeology - Good-looking blocks that need almost no design input What does not: - Two seat axes billed at once, builders and app users, plus record and action caps, so the bill grows with your audience - No code export at all, no source to take away and no migration path off the platform, which is what 2.1 on code ownership means - AI credits are 5 a month on Free and 10 on Basic, enough for a demo rather than a working method - Record and user limits shape the product more than your requirements do Capability checks: - Full-stack backend: No, front end over a data source - Database included: Yes, or connect Airtable and Sheets - Auth included: Yes, with user groups and gated pages - Code export: No, none at all, and no migration path off the platform - GitHub sync: No - One-click deploy: Yes - Custom domain: Yes, paid plans - Mobile or native output: Responsive web and PWA - Team collaboration: Yes - Public API or MCP server: Yes, REST API and MCP server from the entry paid tier, with the vendor noting certain endpoints may be limited to higher plans - Self-hosting the output: No Pricing tiers: - Free: Free monthly. Unlimited apps, 3 builders, 5 app users, 5K records, 500 workflow actions a month - Basic: USD 19 monthly. Custom domain, user groups, more records - Pro: USD 99 monthly. 50 AI credits a month, remove Softr branding, granular permissions FAQ: - Q: Does Softr need Airtable? A: Not any more, it has its own tables, but the Airtable path is still where it is strongest and where most of the integration work has gone. - Q: Does Softr have an API or an MCP server? A: Both, from the entry paid tier, with the vendor's own caveat that certain endpoints may be limited to higher plans. - Q: Can you export a Softr app? A: No. There is no code export of any kind and no migration path off the platform, which is the whole reason code ownership scores 2.1. Plan to rebuild if you ever leave. - Q: Softr or Glide? A: Softr for web portals and client-facing directories. Glide for internal, mobile-shaped tools your staff use on a phone. ### 18.

Macaly produced a working brief on the first attempt in four of our six tests, which is a better first-pass rate than several tools ten times its size, and the interfaces it generates need less restyling than most. Where it falls short is breadth: the integration catalogue is thin, there is no MCP surface, and once a project grows past a handful of models the agent starts losing track of what it has already built. Buy it for version one. Plan on exporting before version three. Dissenting view: One panellist rated Macaly a full star higher, arguing that first-pass success on a fixed brief is the only metric that matters to a non-technical buyer and that we penalise small tools for missing enterprise features their users will never open. Best for: Founders who want a good-looking first version fast and are comfortable exporting it to an engineer later. Not for: Teams that need heavy third-party integration work or an audit trail on every change. Axis scores out of 5: - Reliability: 3.9 - Integrations: 3.4 - SEO and GEO: 3.6 - Design quality: 4.2 - Agent performance: 3.9 - Speed: 4.3 - Value: 4.1 - Scalability: 3.2 - API and MCP access: 2.9 - Code ownership: 3.6 What works: - Strong first-pass success rate on a clear brief - Generated interfaces need less restyling than most tools this size - Full source download on the entry paid tier, not gated behind an enterprise plan - Pricing is a flat monthly figure rather than a credit ledger What does not: - Thin integration catalogue compared with the larger builders - No public API and no MCP server, so it cannot be scripted - Agent loses coherence on projects with many related models - Small team, so support depth is untested at scale Capability checks: - Full-stack backend: Yes - Database included: Yes, hosted Postgres - Auth included: Yes, email and password - Code export: Yes, full source download - GitHub sync: One-way push - One-click deploy: Yes - Custom domain: Yes, paid plans - Mobile or native output: Responsive web only - Team collaboration: Limited, paid plans - Public API or MCP server: No - Self-hosting the output: Yes, after export Pricing tiers: - Free: Free monthly. Limited generations, Macaly subdomain - Pro: USD 25 monthly. Custom domain, code export, more generations FAQ: - Q: Can you export code from Macaly? A: Yes. The entry paid tier includes a full source download of the React and Node project, which is why it scores 3.6 on code ownership rather than the 2.4 typical of closed builders. - Q: Is Macaly good enough for a production SaaS? A: For a small one, yes. It scored 3.9 on reliability, which is solid. Scalability at 3.2 is the constraint, so treat the export path as your growth plan rather than an emergency exit. - Q: How does Macaly compare with Lovable? A: Lovable is stronger on integrations, community and template depth. Macaly is faster to a first result and cheaper to run, with a flat price instead of credits. - Q: Does Macaly have a free tier? A: Yes, with a capped number of generations and a Macaly subdomain. Code export requires a paid plan. ### 19.

Verdict: The most capable tool in this cohort for anything with roles and relationships, and the least forgiving. Momen gives you a real relational model, a generated GraphQL API and row-level permissions that actually work, which is rare here. The cost is a learning curve closer to a framework than a builder, an AI assistant that is the weakest part of the product at 3.3, and no code export at all. Strong choice for a marketplace. Poor choice for a weekend. Dissenting view: Two panellists wanted a higher value score, noting that the published plans undercut Bubble for comparable work. The value axis also weighs the cost of the learning curve, which is where the mark went. Best for: Marketplaces, booking products and multi-role applications that need real permissions. Not for: Anyone who wants to be productive in the first hour, or who needs to leave with the code. Axis scores out of 5: - Reliability: 4.1 - Integrations: 3.7 - SEO and GEO: 3.4 - Design quality: 3.8 - Agent performance: 3.3 - Speed: 3.5 - Value: 4.0 - Scalability: 3.9 - API and MCP access: 3.8 - Code ownership: 2.5 What works: - Row-level permissions that survive an actual multi-role test - Generated GraphQL API makes it scriptable from outside - Scalability at 3.9 is strong for a closed platform What does not: - No code export, so everything you build stays on Momen - The AI assistant is the weakest component of the product - Steepest learning curve of the second cohort Capability checks: - Full-stack backend: Yes - Database included: Yes, own relational store - Auth included: Yes, with roles and row-level rules - Code export: No - GitHub sync: No - One-click deploy: Yes - Custom domain: Yes, paid plans - Mobile or native output: Responsive web and PWA - Team collaboration: Yes - Public API or MCP server: Yes, generated GraphQL API - Self-hosting the output: No Pricing tiers: - Free: Free monthly. Build and preview only, no custom domain - Basic: USD 33 per project, monthly, billed annually. Publishing, custom domain, base capacity - Pro: USD 85 per project, monthly, billed annually. Payments, single sign-on, 10 collaborators, higher capacity FAQ: - Q: Is Momen no-code or low-code? A: No-code in the sense that you never open a file, low-code in the sense that you have to understand data modelling, joins and permissions to get anywhere. - Q: Can you export from Momen? A: No. Code ownership scores 2.5 and that is the main risk to weigh before committing a commercial product to it. - Q: Momen or Bubble? A: Momen for permissions, API access and predictable performance. Bubble for the plugin ecosystem, the community and the far larger pool of contractors who know it. ### 20.

There is no step between USD 20 and USD 200. - Pricing model: Free plan, design mode only, cannot build a working app: 35 credits a month capped at 5 a day. Pro is USD 20 a month for Expo, Android and web, and iOS output starts at USD 200 on Max. - Star ratings counted: 3, community average 4.3/5 - Written reviews counted: 2 (a different number from the star ratings above) - Last verified: 2026-08-20T00:00:00.000Z - Review: https://www.app-builder-index.com/reviews/rork - Spanish edition: https://www.app-builder-index.com/es/opiniones/rork - Profile: https://www.app-builder-index.com/builders/rork Summary: An AI-native mobile builder that turns a prompt into a React Native and Expo app you can preview on your phone in minutes, with source access on paid plans. Verdict: A focused mobile generator that is better at its one job than its price ladder admits. Rork produces React Native and Expo projects from a prompt and the output is closer to something you would keep than most of this cohort, which is why it beats several better-known names on code ownership. Read the tiers carefully before you commit, because the headline number does not buy the platform most buyers want: iOS output starts at the USD 200 tier, while USD 20 covers Expo, Android and web only. If the reason you are here is an iPhone app, that is a ten-fold difference between the plan you were looking at and the plan you need. The top tier compounds the problem: its credit ladder has no published prices above its first step, so the ceiling is a conversation rather than a number. Judged on what it makes rather than how it sells, it is a solid tool for a narrow job. Dissenting view: The data editor wanted a lower value mark, noting that credit consumption in our tests implied a real monthly cost well above the advertised USD 20 for anyone iterating seriously. Best for: Founders who want a credible native app prototype on a real device the same afternoon. Not for: Production apps with complex state, and anyone who dislikes credit-based pricing. Axis scores out of 5: - Reliability: 3.7 - Integrations: 3.3 - SEO and GEO: n/a, axis not applicable to this tool - Design quality: 4.2 - Agent performance: 4.1 - Speed: 4.5 - Value: 2.9 - Scalability: 3.1 - API and MCP access: 3.0 - Code ownership: 3.9 What works: - React Native and Expo output you would plausibly keep and maintain - One narrow job, done without the ceremony of a general-purpose builder What does not: - iOS output starts at the USD 200 tier. The USD 20 tier covers Expo, Android and web only - The top tier's credit ladder has no published prices above its first step, so the upper bound is unquotable Capability checks: - Full-stack backend: Partial, hosted backend - Database included: Yes, basic hosted store - Auth included: Yes - Code export: Yes, Expo project on paid plans - GitHub sync: One-way push - One-click deploy: Yes, Expo preview and store builds - Custom domain: Not applicable - Mobile or native output: React Native and Expo. iOS output starts at the USD 200 tier, and the USD 20 tier covers Expo, Android and web only - Team collaboration: Limited - Public API or MCP server: No - Self-hosting the output: Yes, after export Pricing tiers: - Free: Free monthly. Design mode only, cannot build a working app, 35 credits a month capped at 5 a day - Pro: USD 20 monthly. Monthly credits, Expo, Android and web output - Max: USD 200 monthly. iOS output, larger credit pool FAQ: - Q: How much does an iPhone app actually cost with Rork? A: iOS output starts at the USD 200 tier. The USD 20 tier covers Expo, Android and web only, so check which platform you need before comparing the entry price with anything else here. - Q: Is the top tier's price predictable? A: No. Its credit ladder publishes a price for the first step only, so the ceiling has to be negotiated rather than read. ### 21.

Verdict: Buy for a website, skip for an application. Zite is exceptional value if what you actually need is a handsome, fast, well-marked-up site with a form on it: publishing takes minutes, the on-page SEO defaults are better than most full-stack builders manage, and users and apps are unlimited on every plan, including the free one. It scored 3.8 on our SEO and GEO axis, ahead of Replit and Base44, which tells you where its engineering attention has gone. The ceiling arrives fast though. Once you need user roles or a relational model, Zite is not the tool. Dissenting view: Two panellists argued Zite should not be in an AI app builder index at all, on the grounds that it is a site builder with an assistant and including it invites confused comparisons. The editor in chief overruled them: buyers are demonstrably shopping across both categories, search demand for "AI app builder" surfaces Zite, and an index that quietly omits the tool someone is about to buy has failed at its one job. The dissent stands on the record. Best for: Marketing sites, landing pages and simple lead-capture apps that need to look good and rank. Not for: Applications with real data models, user roles, or anything you will still be extending in a year. Axis scores out of 5: - Reliability: 3.5 - Integrations: 3.2 - SEO and GEO: 3.8 - Design quality: 4.1 - Agent performance: 3.6 - Speed: 4.4 - Value: 4.0 - Scalability: 3.0 - API and MCP access: 2.6 - Code ownership: 2.4 What works: - Unlimited users and unlimited apps on every plan, including the free one, with no per-user fees - On-page SEO defaults are better than most full-stack builders - Publishing is genuinely instant and the output is fast - Templates look current rather than dated What does not: - No code export at all, so you cannot leave with your work - No meaningful database or relational modelling - No public API or MCP surface for automation - Hits a hard ceiling as soon as the project becomes an application Capability checks: - Full-stack backend: No - Database included: Limited, form and list storage - Auth included: Limited - Code export: No - GitHub sync: No - One-click deploy: Yes - Custom domain: Yes, paid plans - Mobile or native output: Responsive web only - Team collaboration: Limited - Public API or MCP server: No - Self-hosting the output: No Pricing tiers: - Free: Free monthly. Zite subdomain, basic pages, platform badge - Pro: USD 20 monthly, billed annually. Custom domain, badge removal, forms USD 240 billed annually. USD 25 billed monthly. - Business: USD 75 monthly. 400 credits a month, 250,000 records, unlimited custom domains, white-label emails USD 900 billed annually. FAQ: - Q: Is Zite an app builder or a website builder? A: Mostly a website builder with an AI assistant. It handles landing pages, marketing sites and light form-driven tools well. It does not handle relational data, roles or complex logic. - Q: Can you export a Zite site? A: No. There is no code export, which is why it scores 2.4 on code ownership, among the lowest in this index. Treat anything you build as living on Zite permanently. - Q: Is Zite good for SEO? A: Better than you would expect. It scored 3.8 on our SEO and GEO axis, ahead of Replit and Base44, thanks to clean markup, fast pages and sane metadata defaults. - Q: What should I use instead for a real app? A: Lovable or Totalum if you need a database and users, v0 if you have a developer and an existing API. ### 22. a0.dev - 3.6/5 - Slug: a0-dev - Official site: https://a0.dev - Category: mobile - Price from: USD 20 / month, billed monthly (the vendor's own currency, not converted). Free tier: no - Price note: Pro plan. The vendor's pricing page shows a bare dollar sign and does not state a currency anywhere, so USD on this row is our own label rather than the vendor's. The vendor publishes no free tier at all, and the only other plan is Max at USD 200 a month for 1,250 credits. - Pricing model: No free tier is published. Pro is USD 20 a month and the only other plan is Max at USD 200 a month for 1,250 credits. - Star ratings counted: 3, community average 4.3/5 - Written reviews counted: 2 (a different number from the star ratings above) - Last verified: 2026-08-20T00:00:00.000Z - Review: https://www.app-builder-index.com/reviews/a0-dev - Spanish edition: https://www.app-builder-index.com/es/opiniones/a0-dev - Profile: https://www.app-builder-index.com/builders/a0-dev Summary: A chat-driven mobile app generator producing React Native and Expo projects, notable for how quickly it applies small changes and how little ceremony it demands. Verdict: The deployment story is the reason to look at it, and we had understated it. a0.dev does full one-click publishing to the App Store and Google Play, including creating the App Store Connect listing and uploading the build for you, plus over-the-air updates afterwards. For a solo builder who has never fought an Apple submission, that is worth more than another point of design polish. What you should not assume is a backend. There is no a0 datastore: the vendor describes the backend as powered by Convex or Supabase, which you sign up for separately, so budget a second vendor from day one. Several cells on this page previously claimed capabilities the vendor does not publish, and they now say so plainly: authentication and GitHub sync are not published by the vendor as of August 2026, meaning we could not verify them either way rather than that they are absent. Custom domain is a real Pro feature, listed as custom domain and no a0 branding. One published weakness to plan around: Android in-app payments are explicitly not supported yet. There is still no public API and no MCP server. Dissenting view: One panellist argued the scalability mark punishes a tool for not attempting something it explicitly does not sell, and that prototyping tools need their own axis weighting. Best for: Rapid mobile prototyping where the loop between an idea and seeing it matters more than anything else. Not for: Anything that needs integrations, or a team, or a roadmap.

Monthly credits, code export, device preview The vendor's pricing page shows a bare dollar sign and names no currency, so the amounts here are shown without one. - Max: $200 monthly. 1,250 credits a month FAQ: - Q: Does a0.dev include a database? A: No. There is no a0 datastore. The vendor describes the backend as powered by Convex or Supabase, which you sign up for separately, so plan for a second vendor and a second bill. - Q: Can it publish to the app stores for me? A: Yes, and this is its strongest feature. One-click publishing to the App Store and Google Play includes creating the App Store Connect listing and uploading the build, with over-the-air updates afterwards. - Q: Does it handle payments? A: Not fully. Android in-app payments are explicitly not supported yet. - Q: Is there an API or MCP server? A: No. Neither is published, so a0.dev cannot be driven from an AI agent or a script. ### 23.

Verdict: A specialist that does one thing beautifully, and a second thing we had missed. If you have a finished Figma file and an API, Bravo turns them into a native app that looks exactly like the design, and design at 4.4 reflects that fairly. The part our previous verdict denied is Bravo MCP, shipped in Bravo 4.0 as a beta inside the Solo plan: in the vendor's words it "plugs into Claude, ChatGPT, Cursor, or any MCP-compatible AI client and lets you build native apps from inside the AI conversation you already use", with React Native output, a Convex backend included and realtime sync from Figma. So "no backend, bring your own API" is wrong on that path. Auth and payments are further along than we said too: OAuth 2.0 login, custom authentication and Firebase email and phone login are Solo platform features, with Stripe and in-app purchases as an add-on. The real ceiling is one we never mentioned and it is the honest explanation of the 2.6 scalability mark: 15 screens per app on Starter, 30 on Solo. That is what limits Bravo to small applications, not the absence of features. Dissenting view: The editor in chief held that a beta MCP surface should not lift the agent score yet, and that a product whose ceiling is 30 screens is a bridge rather than a platform however it is driven. Best for: Designers with a finished Figma prototype and an API to plug into it. Not for: Anyone without a design file, or without a backend already built.

Free forever, preview in the Bravo Vision app - SOLO: USD 22 monthly. Published app, API bindings, store publishing The vendor states prices in USD are based on the current exchange rate and the exact price is shown at checkout. - Professional services: On request quote. Vendor-built and vendor-supported delivery FAQ: - Q: Do you need Figma to use Bravo Studio? A: On the classic path yes: Figma is the editor, and Bravo maps layers to native components and binds them to your API, with realtime sync. On the Bravo MCP path you build from inside an AI conversation instead. - Q: Does Bravo build a backend? A: On the Bravo MCP path, yes: a Convex backend is included. On the classic path you supply the API, and Xano and Supabase are common choices. - Q: How large an app can Bravo build? A: Fifteen screens per app on Starter and thirty on Solo. That ceiling, rather than any missing feature, is why scalability scores 2.6. - Q: Does Bravo support login and payments? A: Yes. OAuth 2.0 login, custom authentication and Firebase email and phone login are Solo platform features, and Stripe with in-app purchases is available as an add-on. ### 24.

Verdict: Interesting, not yet dependable. Emergent has the most ambitious agent architecture in this index: give it a real brief and it produces a task decomposition that reads like something a competent tech lead would write, then works through it across many files without asking permission every thirty seconds. When it lands, it lands big. Our panel gave it 4.2 on agent performance, among the highest here. The trouble is variance. The same brief run twice produced materially different quality, and the failure mode is quiet: plausible code that does not work, discovered later than you would like. Dissenting view: Our testing lead wanted a higher score, arguing that variance is what every agent product looked like eighteen months before it got good, and that Emergent's planning quality is the leading indicator that matters. He would put it above Bolt and level with Base44. The majority held that an index exists to tell buyers what will happen this quarter, not what might happen next year, and that a quiet failure mode is worse than a loud one because it wastes review time. Best for: Developers who want to hand off a well-specified multi-file change and review the result rather than watch it happen. Not for: Anyone who needs the app to be right the first time, or who cannot read the diff to check. Axis scores out of 5: - Reliability: 3.4 - Integrations: 3.6 - SEO and GEO: 3.2 - Design quality: 3.7 - Agent performance: 4.2 - Speed: 3.9 - Value: 3.8 - Scalability: 3.4 - API and MCP access: 3.0 - Code ownership: 3.4 What works: - Best task decomposition and planning of any agent we tested - Comfortable making coordinated changes across many files at once - Genuinely low supervision overhead when a run goes well - Reasonable value per completed feature when it succeeds What does not: - High run-to-run variance from the same brief - Failures are quiet: plausible code that does not actually work - Thin integration and API surface compared to the leaders - Documentation lags the product by several releases Capability checks: - Full-stack backend: Yes - Database included: Yes, managed - Auth included: Yes - Code export: Yes - GitHub sync: Yes - One-click deploy: Yes - Custom domain: Yes, paid plans - Mobile or native output: Limited - Team collaboration: Limited - Public API or MCP server: Limited - Self-hosting the output: Partial Pricing tiers: - Free: Free monthly. 10 free monthly credits, core platform features - Standard: USD 20 monthly.

Role-based access control, single sign-on, shared team workspaces FAQ: - Q: Is Emergent reliable enough to use at work? A: Only with review. Our panel scored it 3.4 on reliability because the same brief produced materially different quality across runs, and the failures are quiet rather than loud. Treat its output like a pull request from a fast, unpredictable junior. - Q: What does Emergent do better than Lovable? A: Planning. Give it a real multi-part brief and it decomposes the work more sensibly than anything else in this index, then executes across many files without constant prompting. - Q: Who should actually buy Emergent? A: Developers who can read a diff. If you can review the output, the leverage is real. If you cannot, the quiet failure mode will cost you more than it saves. - Q: Is it a full-stack builder? A: Yes, with a managed database and auth, but the integration surface is thinner than Lovable, Replit or Totalum, and the API access is limited. ### 25.

The vendor lists a single entry price of USD 20 a month with a one line usage descriptor and no plan name. - Star ratings counted: 18, community average 4.0/5 - Written reviews counted: 3 (a different number from the star ratings above) - Last verified: 2026-08-20T00:00:00.000Z - Review: https://www.app-builder-index.com/reviews/manus - Spanish edition: https://www.app-builder-index.com/es/opiniones/manus - Profile: https://www.app-builder-index.com/builders/manus Summary: A general-purpose AI agent that plans and executes multi-step work in its own environment, including building and deploying small web applications from a single instruction. Verdict: Impressive, expensive and not really a builder. Manus plans and executes long chains of work in its own sandbox, and it scored 4.3 on agent performance because it genuinely completes tasks that stump single-purpose tools. As an app platform it is weak: no project structure to return to, scalability at 3.0, and credit consumption that made it the least predictable cost in our tests. Use it for a one-off build or a task that spans research, data and code. Do not use it as your product surface. Dissenting view: One panellist argued Manus should be scored as an agent platform rather than an app builder and that its 3.0 scalability mark reflects a category mismatch rather than a product weakness. Best for: One-off builds, research-plus-build tasks and automations that span more than one tool. Not for: Iterating on a product over months, or anything where cost predictability matters. Axis scores out of 5: - Reliability: 3.5 - Integrations: 3.9 - SEO and GEO: 3.2 - Design quality: 3.6 - Agent performance: 4.3 - Speed: 3.4 - Value: 3.3 - Scalability: 3.0 - API and MCP access: 3.7 - Code ownership: 3.5 What works: - Agent performance at 4.3 on long, multi-step tasks other tools abandon - Spans research, data work and code in a single instruction - Hands over real files rather than trapping the output What does not: - Credit consumption is the least predictable cost in the index - No durable project structure to iterate on over months - Scalability at 3.0 makes it unsuitable as a product platform Capability checks: - Full-stack backend: Yes, in its sandbox - Database included: Yes, whatever it provisions - Auth included: If you ask for it - Code export: Yes, it hands over files - GitHub sync: Yes, it can push - One-click deploy: Yes, it deploys for you - Custom domain: Yes, with configuration - Mobile or native output: Responsive web only - Team collaboration: Limited - Public API or MCP server: Yes, API and MCP support - Self-hosting the output: Yes, after handover Pricing tiers: - Entry plan: USD 20 monthly. Monthly credits, longer tasks, more concurrency The vendor publishes no name for this plan. - Higher plan: Not captured monthly. Large credit pool, priority compute, extended runs Plan exists, price not captured in our 19 and 20 August 2026 check. FAQ: - Q: Is Manus an app builder? A: Not primarily. It is a general agent that can build apps. One panellist argued it should be scored in a separate category entirely. - Q: How much does Manus really cost? A: More than the sticker price if you use it heavily. Credit consumption varied widely across our six briefs, which is why value scores 3.3. - Q: Manus or Lovable for an MVP? A: Lovable. It gives you a project you can keep editing. Manus is better for one-off work that crosses tool boundaries. ### 26. Draftbit - 3.5/5 - Slug: draftbit - Official site: https://draftbit.com - Category: mobile - Price from: USD 12 / month, billed monthly (the vendor's own currency, not converted). Free tier: yes - Price note: Standard plan. Pro is USD 24, Team is USD 120, and Enterprise is quote based. - Pricing model: Five tiers: Free, Standard at USD 12 a month, Pro at USD 24, Team at USD 120 and a quote-based Enterprise plan. - Star ratings counted: 5, community average 3.6/5 - Written reviews counted: 2 (a different number from the star ratings above) - Last verified: 2026-08-20T00:00:00.000Z - Review: https://www.app-builder-index.com/reviews/draftbit - Spanish edition: https://www.app-builder-index.com/es/opiniones/draftbit - Profile: https://www.app-builder-index.com/builders/draftbit Summary: A visual builder that produces React Native and Expo projects with full source export, a built-in Supabase backend on every tier, and bring-your-own AI keys across Claude, ChatGPT, OpenAI, Anthropic and OpenRouter. Verdict: A better-equipped product than our previous verdict described. Draftbit produces real React Native and Expo projects you can export and own, which earns 4.2 on code ownership, and the visual editor is pleasant. The current feature list is where we were most out of date: Claude Code and OpenAI Codex integration, bring-your-own AI across Claude, ChatGPT, OpenAI, Anthropic and OpenRouter with the vendor stating that Draftbit credits are not required, a built-in Supabase backend on every tier including Free, sandbox concurrency, multi-agent execution, custom MCP server integrations, and web and website output alongside mobile. Read the tier gates carefully: full code editing and export start at Standard, export to GitHub starts at Pro, and the custom MCP server integrations on Pro mean Draftbit consuming your MCP servers, not publishing one. Draftbit ships no MCP server of its own and no platform API, so its build lifecycle is still not agent-callable from outside, which is what the 3.4 API mark measures. Dissenting view: One panellist argued that bring your own key is a cost transfer rather than a saving, since the buyer ends up managing accounts and spend at up to five AI vendors instead of one line on an invoice. Best for: React Native developers who want a visual head start, their own AI keys and a backend that is already there. Not for: Non-developers, and anyone who wants the platform itself to be agent-callable from outside. Axis scores out of 5: - Reliability: 3.4 - Integrations: 4.0 - SEO and GEO: 2.5 - Design quality: 3.6 - Agent performance: 3.9 - Speed: 3.5 - Value: 3.9 - Scalability: 3.5 - API and MCP access: 3.4 - Code ownership: 4.2 What works: - Real React Native and Expo source export at 4.2 on code ownership, with full code editing from Standard - Bring your own AI across Claude, ChatGPT, OpenAI, Anthropic and OpenRouter, with the vendor stating Draftbit credits are not required - Built-in Supabase backend on every tier including Free, so the data half of the app is not a second purchase - Sandbox concurrency and multi-agent execution, plus Claude Code and OpenAI Codex integration What does not: - No Draftbit MCP server and no platform API, so the build lifecycle is not agent-callable from outside - Tier gates split the workflow: full code editing and export at Standard, export to GitHub at Pro - Custom MCP server integrations mean Draftbit consuming your servers, which is not the same as being programmable itself - SEO and GEO at 2.5 is low, so the web output is not the reason to buy it Capability checks: - Full-stack backend: Yes, a built-in Supabase backend - Database included: Yes, a built-in Supabase backend, which is Postgres, on every tier including Free - Auth included: Bring your own - Code export: Full code editing and export from Standard - GitHub sync: Export to GitHub from Pro - One-click deploy: Expo builds - Custom domain: Yes, from the Standard tier - Mobile or native output: Native iOS and Android via Expo, plus web and website output - Team collaboration: Yes, paid plans - Public API or MCP server: Custom MCP server integrations from Pro, which is Draftbit consuming your MCP servers. Draftbit publishes no MCP server of its own and no platform API - Self-hosting the output: Yes, after export Pricing tiers: - Free: Free monthly. Build and preview, limited components - Standard: USD 12 monthly. Code export, more screens - Pro: USD 24 monthly. GitHub sync, custom code, more builds - Team: USD 120 monthly. Collaborators, shared design system, roles - Enterprise: On request quote. Procurement, support terms, volume seats FAQ: - Q: Can you export code from Draftbit? A: Yes. Full code editing and export start at Standard, and export to GitHub starts at Pro. That export is the main reason to choose it, and the basis of its 4.2 code ownership score. - Q: Does Draftbit include a backend? A: Yes, a built-in Supabase backend, which is Postgres, on every tier including Free. - Q: Can I use my own AI keys? A: Yes, across Claude, ChatGPT, OpenAI, Anthropic and OpenRouter, and the vendor states that Draftbit credits are not required. Claude Code and OpenAI Codex integration are listed too. - Q: Does Draftbit have an MCP server? A: No. Pro adds custom MCP server integrations, which is Draftbit consuming your MCP servers. It publishes neither an MCP server of its own nor a platform API, so nothing outside can drive a build. ### 27. Bubble - 3.5/5 - Slug: bubble - Official site: https://bubble.io - Category: full_stack - Price from: USD 29 / month, billed annually (the vendor's own currency, not converted). Free tier: yes - Price note: Starter plan on the Web plan family, billed annually. The same pricing page publishes a Mobile family from USD 42 and a Web and Mobile family from USD 59, all billed annually, and shows no monthly-billed rate for any tier. - Pricing model: Free plan for building and testing only: it cannot buy workload tiers or enable overages, so it hard-stops at 50K workload units. Paid plans from USD 29 a month billed annually on the Web plan family, plus workload charges. - Star ratings counted: 42, community average 4.0/5 - Written reviews counted: 3 (a different number from the star ratings above) - Last verified: 2026-08-20T00:00:00.000Z - Review: https://www.app-builder-index.com/reviews/bubble - Spanish edition: https://www.app-builder-index.com/es/opiniones/bubble - Profile: https://www.app-builder-index.com/builders/bubble Summary: The longest-running visual full-stack platform, with its own database, workflow engine and a plugin ecosystem nothing else here comes close to, now with an AI assistant bolted on the front. Verdict: Still the most capable platform here, still the hardest to leave. Bubble scores 4.5 on integrations because thirteen years of plugins and a large contractor market genuinely solve problems the AI-native tools cannot, and its native mobile story is better than we published: the vendor's own FAQ says "In Bubble, native mobile apps run on React Native", with store publishing, build submissions and unlimited over-the-air updates, so calling it a wrapper was inaccurate. The Data and Workflow APIs are real and useful. What does not exist is an MCP server: the vendor's March 2026 founder AMA says it is "on our radar, but not on the roadmap yet", the editor API is not open either, and every "Bubble MCP" you will find is a community project on forum.bubble.io. The other costs are unchanged: no code export at all, one of the weakest performance profiles in the index at 3.0 on speed, and workload pricing that surprises people in month three, though storage at least is published flatly at USD 3 per 100 GB a month. Choose it deliberately, with an exit you have accepted you do not have. Dissenting view: The testing lead wanted a lower reliability mark after two workload throttles during our runs. The rest of the panel held at 4.2, on the grounds that throttling under load is a pricing failure rather than a reliability failure. Best for: Complex operational products where the plugin ecosystem and the contractor pool matter more than speed. Not for: Anyone who needs to leave with the code, or who is judged on page speed. Axis scores out of 5: - Reliability: 4.2 - Integrations: 4.5 - SEO and GEO: 3.2 - Design quality: 3.4 - Agent performance: 3.1 - Speed: 3.0 - Value: 2.8 - Scalability: 3.6 - API and MCP access: 3.2 - Code ownership: 2.2 What works: - Deepest plugin ecosystem of any tool in the index, with integrations at 4.5 - Native mobile apps run on React Native, with store publishing, build submissions and unlimited over-the-air updates - Large market of experienced contractors you can actually hire - Data and Workflow APIs make it scriptable and automatable, and storage is published flatly at USD 3 per 100 GB a month What does not: - No official MCP server. The vendor's March 2026 founder AMA calls it on our radar, but not on the roadmap yet, and the editor API is not open either - No code export, and thirteen years of accumulated lock-in to go with it - Among the slowest published pages in the index, at 3.0 on speed - Workload-based pricing makes cost hard to forecast, even though storage is priced flatly Capability checks: - Full-stack backend: Yes - Database included: Yes, own store - Auth included: Yes, with privacy rules - Code export: No - GitHub sync: No - One-click deploy: Yes - Custom domain: Yes, paid plans - Mobile or native output: Native mobile apps run on React Native, with store publishing, build submissions and unlimited over-the-air updates - Team collaboration: Yes, paid plans - Public API or MCP server: Data and Workflow APIs, yes. No official MCP server, the editor API is not open, and every Bubble MCP in circulation is a community project - Self-hosting the output: No Pricing tiers: - Free: Free monthly. Build and test only, no custom domain Cannot buy workload tiers or enable overages, so it stops at 50K workload units. - Starter: USD 29 monthly, billed annually. Custom domain, base workload allowance Web plan family. Mobile is USD 42 and Web and Mobile is USD 59. - Growth: USD 119 monthly, billed annually. More workload, more seats, API limits raised Web plan family. Mobile is USD 169 and Web and Mobile is USD 209. - Team: USD 349 monthly, billed annually. Higher workload, sub-apps, priority support Web plan family. Mobile is USD 449 and Web and Mobile is USD 549. - Enterprise: On request quote. Volume workload, procurement, support terms - Agency: On request quote. A separate account type for people building for clients FAQ: - Q: Can you export a Bubble app? A: No. There is no code export, which is why it scores 2.2 on code ownership. Budget for a rebuild if you ever need to leave. - Q: Does Bubble have an MCP server? A: No official one. The vendor's own March 2026 founder AMA describes it as "on our radar, but not on the roadmap yet", and says the editor API is not open either. Anything called a Bubble MCP is a community project on forum.bubble.io. The Data and Workflow APIs are official and do work. - Q: Are Bubble mobile apps real native apps? A: Yes. The vendor's FAQ states that native mobile apps run on React Native, with store publishing, build submissions and unlimited over-the-air updates. - Q: Is Bubble still worth it in 2026? A: For complex operational products, yes. It scores 4.5 on integrations and you can hire people who know it. For a marketing site or a simple MVP it is overkill. ### 28.

Free tier: yes - Price note: The vendor's page shows a bare dollar sign and does not state the currency anywhere. - Pricing model: Free plan with monthly credits. Pro at $17 a month.

Verdict: Buy on looks, and know what you are buying. Trickle produces the most tasteful output of the lightweight group and scored 4.3 on design, above every full-stack builder except Lovable and Totalum. If your job is a microsite, a campaign page or an interactive form that has to look considered, this is a genuinely good tool at a genuinely low price. It is also, by our measurements, the least capable backend here: scalability 2.9 and API and MCP 2.5, the latter the bottom of the index. Nothing about that is a bug; it is the product. Dissenting view: Our front-end reviewer files the opposite dissent to the usual one: she thinks the overall star rating flatters the backend weaknesses rather than punishing them, because a 2.9 on scalability still reads as almost three out of five to a casual reader, when the honest description is that there is no meaningful scaling story at all. She would prefer axis floors, so that a missing capability scores 1.0 and not 2.5. That change is on our methodology roadmap and is not in the launch scores. Best for: Designers and marketers building visually distinctive pages, microsites and interactive forms. Not for: Any application with users, roles, records or a second year of development ahead of it. Axis scores out of 5: - Reliability: 3.5 - Integrations: 3.1 - SEO and GEO: 3.6 - Design quality: 4.3 - Agent performance: 3.4 - Speed: 4.0 - Value: 4.0 - Scalability: 2.9 - API and MCP access: 2.5 - Code ownership: 2.6 What works: - Best visual defaults of the lightweight builders, 4.3 on design - Low price for the quality of output it produces - Fast, pleasant editing loop for pages and forms - Decent on-page SEO for a design-led tool What does not: - Lowest API and MCP score in this index at 2.5 - Scalability of 2.9, among the lowest in the index - No code export, so no exit path - Not an application platform in any meaningful sense Capability checks: - Full-stack backend: No - Database included: Limited, form and list storage - Auth included: Limited - Code export: No - GitHub sync: No - One-click deploy: Yes - Custom domain: Yes, paid plans - Mobile or native output: Responsive web only - Team collaboration: Yes, basic - Public API or MCP server: No - Self-hosting the output: No Pricing tiers: - Free: Free monthly. Monthly credits, Trickle subdomain - Pro: $17 monthly. Custom domain, more credits, badge removal The vendor's page shows a bare dollar sign and does not state the currency anywhere. - Premium: $42 monthly. More monthly credits, 3 custom domains, 10,000 database rows FAQ: - Q: What is Trickle actually for? A: Microsites, campaign pages and interactive forms that need to look designed. On our design axis it scored 4.3, above every full-stack builder except Lovable and Totalum. - Q: Can Trickle build a web app with logins and data? A: Not really. Storage is limited to forms and lists, and there is no real auth or roles model. Scalability scores 2.9, among the lowest in this index. - Q: Is there a way to export from Trickle? A: No, there is no code export. It scores 2.6 on code ownership. Build here knowing the work stays here. - Q: Trickle or Zite? A: Trickle if visual distinctiveness is the priority, Zite if search performance and page volume matter more. They are close competitors and both are cheap. ### 29. Rocket.new - 3.5/5 - Slug: rocket-new - Official site: https://rocket.new - Category: mobile - Price from: USD 25 / month, billed monthly (the vendor's own currency, not converted). Free tier: yes - Price note: Pro plan. The vendor's page shows a bare dollar sign and does not state the currency anywhere. Rocket is $50 a month and Booster is $250 a month. A Yearly toggle advertises save 20%, but the yearly figures were not captured, so no yearly number should be published. - Pricing model: Free plan with 20 trial credits. Three paid tiers, each a flat monthly platform fee with unlimited team members: Pro at $25, Rocket at $50 and Booster at $250, carrying 100, 250 and 1,500 monthly credits respectively. The vendor's page shows a bare dollar sign and never states the currency. - Star ratings counted: 8, community average 3.4/5 - Written reviews counted: 5 (a different number from the star ratings above) - Last verified: 2026-09-06T00:00:00.000Z - Review: https://www.app-builder-index.com/reviews/rocket-new - Spanish edition: https://www.app-builder-index.com/es/opiniones/rocket-new - Profile: https://www.app-builder-index.com/builders/rocket-new Summary: A builder that treats mobile as a first-class output, generating Flutter and React Native alongside a web target from the same prompt. Verdict: Buy only if mobile is the point. Rocket.new is the clearest answer in this index to a specific question: what if the output needs to be an app store app rather than a website? It generates Flutter and React Native targets from the same brief, the screens look genuinely native rather than a web page in a shell, and for a team with no mobile engineers that is a real shortcut. Everything else is mid-table or below. Reliability is shaky, the SEO axis score of 3.0 is among the weakest here, and the credit model prices exploration higher than it should. Dissenting view: One panellist argued the overall score understates it because our weights punish a mobile tool: SEO and GEO carries thirteen percent, which is close to irrelevant for a product shipped through app stores. He proposed a use-case weighted variant. We declined for launch, because a single published weighting is what makes the index comparable, but the point is fair and we say so on the review page rather than burying it. Best for: Teams who need a credible mobile app prototype and do not have mobile engineers. Not for: Web-first products, content sites, or anything where organic search is the growth channel. Axis scores out of 5: - Reliability: 3.3 - Integrations: 3.4 - SEO and GEO: 3.0 - Design quality: 4.0 - Agent performance: 3.7 - Speed: 4.1 - Value: 3.6 - Scalability: 3.2 - API and MCP access: 2.8 - Code ownership: 3.0 What works: - Genuine mobile output rather than a web view in a wrapper - Flutter and React Native both available from one brief - Screens look native, with platform-appropriate navigation patterns - Useful shortcut for teams with no mobile engineering capacity What does not: - SEO and GEO of 3.0, among the weakest in this index - Reliability is below the tools it is priced against - Credit model makes iteration expensive - Thin automation surface, limited API access Capability checks: - Full-stack backend: Partial - Database included: Yes, managed - Auth included: Yes - Code export: Yes, Flutter or React Native - GitHub sync: Yes - One-click deploy: Yes, web target - Custom domain: Yes, paid plans - Mobile or native output: Yes, Flutter and React Native - Team collaboration: Limited - Public API or MCP server: Limited - Self-hosting the output: Partial Pricing tiers: - Free: Free monthly. 20 trial credits, unlimited team members - Pro: $25 monthly. 100 monthly credits, unlimited team members The vendor's page shows a bare dollar sign and does not state the currency anywhere. - Rocket: $50 monthly. 250 monthly credits, unlimited team members - Booster: $250 monthly. 1,500 monthly credits, unlimited team members FAQ: - Q: Is Rocket.new the best AI builder for mobile apps? A: It is a strong mobile-first option, though FlutterFlow scores higher overall on mobile. It generates Flutter and React Native targets and the screens follow platform conventions rather than looking like a wrapped website. - Q: Why is Rocket.new's overall score mid-table? A: Because our published weights give thirteen percent to SEO and GEO, which matters little for app store distribution. One of our panellists dissents on exactly this point and we publish his objection on the review page. - Q: Can you export the code? A: Yes, as Flutter or React Native source on paid plans, though the backend layer remains partly hosted. We score it 3.0 on code ownership. - Q: What is the biggest risk? A: Reliability. At 3.3 it sits below the tools it competes with on price, and our testers hit more regenerations per finished screen than on Lovable or Base44. ### 30. AppMaster - 3.4/5 - Slug: appmaster - Official site: https://appmaster.io - Category: full_stack - Price from: from USD 175 / month, billed yearly (the vendor's own currency, not converted). Free tier: yes - Price note: Startup plan, billed yearly. Every AppMaster headline price carries a from prefix, so all four published figures are floors and not prices. From USD 195 billed monthly. Business is from USD 955 a month. - Pricing model: A free subscription to experiment with your first project, then paid plans from USD 195 a month. Every published figure carries a from prefix, so treat all of them as floors. - Star ratings counted: 3, community average 4.0/5 - Written reviews counted: 2 (a different number from the star ratings above) - Last verified: 2026-08-20T00:00:00.000Z - Review: https://www.app-builder-index.com/reviews/appmaster - Spanish edition: https://www.app-builder-index.com/es/opiniones/appmaster - Profile: https://www.app-builder-index.com/builders/appmaster Summary: A no-code platform that compiles your project into Go services, Vue web applications and native mobile builds, and that gates the source download behind a quote-only Enterprise contract. Verdict: The most unusual proposition in the index, and the one whose headline promise we got wrong. AppMaster does not interpret your project at runtime, it compiles it, and we used to recommend it on the strength of source you could download and walk away with. The vendor's own pricing FAQ says otherwise, verbatim: "Downloading source code available only for accounts with Enterprise Plan. Contact us to request Enterprise plan." Startup and Startup+ get database and file-storage export only. Business, from USD 955 a month, adds backend binaries and Docker images. Source is quote-only Enterprise. For every buyer below a custom contract, the thing we recommended it for does not exist, which is what 2.4 on code ownership now reflects. What survives is real: compiled Go services behind a 4.3 scalability mark, 4.3 on speed, and generated apps that come with documented REST APIs. Note which API we rate, though. The generated apps expose documented REST APIs; AppMaster itself publishes no API for driving the platform and no MCP server, and the API and MCP axis rates the platform, not its output, which is why it sits at 2.6. The interface is dense and dated, design output is plain, and the entry paid tier starts at USD 175 a month billed yearly, or USD 195 billed monthly, the highest entry price in the index. Dissenting view: One panellist argued that compiled binaries and Docker images from the Business tier are ownership enough for most buyers, and that scoring the platform down for gating the raw source overweights a scenario few teams ever exercise. Best for: Teams on a Business or Enterprise contract who want compiled services they can run on their own infrastructure. Not for: Anyone below Business who is buying it for the source code, and anyone with a small budget. Axis scores out of 5: - Reliability: 4.0 - Integrations: 3.6 - SEO and GEO: 3.1 - Design quality: 3.0 - Agent performance: 2.9 - Speed: 4.3 - Value: 2.4 - Scalability: 4.3 - API and MCP access: 2.6 - Code ownership: 2.4 What works: - Compiled Go services rather than an interpreted runtime, behind 4.3 on scalability and 4.3 on speed - Docker images and backend binaries from the Business tier, so the running system can live on your infrastructure - The applications it generates come with documented REST APIs What does not: - Source code download is Enterprise only and quote priced. The vendor states it plainly: downloading source code is available only for accounts with the Enterprise plan - Docker self-hosting starts at Business, from USD 955 a month. Below that there is nothing to self-host - No platform API and no MCP server for driving AppMaster itself, which is what the 2.6 API mark measures - Highest entry price of any paid tier in the index, from USD 175 a month billed yearly or USD 195 billed monthly, with a dense and dated interface Capability checks: - Full-stack backend: Yes, compiled Go - Database included: Yes, Postgres - Auth included: Yes - Code export: Enterprise only, Docker images from Business, data and file export on all paid tiers - GitHub sync: No, and the source download itself is Enterprise only - One-click deploy: Yes, or deploy binaries yourself - Custom domain: Yes - Mobile or native output: Native iOS and Android builds - Team collaboration: Yes, paid plans - Public API or MCP server: The apps it generates expose documented REST APIs. AppMaster itself publishes no API for driving the platform and no MCP server, and this axis rates the platform - Self-hosting the output: Docker self-hosting starts at Business, below that there is nothing to self-host Pricing tiers: - Free: Free monthly. A free subscription to experiment with your first project The vendor publishes no name for this plan. - Startup: USD 195 monthly. Deployment, source export, one application From USD 195, or from USD 175 billed yearly. - Startup+: USD 299 monthly. More applications and resources From USD 299. - Business: USD 955 monthly. Multiple apps, more resources, mobile builds From USD 955. - Enterprise: On request quote. Volume terms, procurement, support FAQ: - Q: Can you download AppMaster source code? A: Only on Enterprise. The vendor's pricing FAQ says "Downloading source code available only for accounts with Enterprise Plan. Contact us to request Enterprise plan." Startup and Startup+ get database and file-storage export, Business adds backend binaries and Docker images, and Enterprise is quote only. That gate is why code ownership scores 2.4. - Q: Is AppMaster no-code? A: It is marketed that way, but the concepts are developer concepts. Expect to understand data models, endpoints and business processes. - Q: Does AppMaster have an API or an MCP server? A: The applications it generates expose documented REST APIs. AppMaster itself publishes neither an API for driving the platform nor an MCP server. Our API and MCP axis rates the platform rather than its output, which is why the score is 2.6. - Q: Why is it so expensive? A: Deployment starts at Startup, from USD 195. Self-hosting via Docker starts at Business, from USD 955. The free subscription only lets you experiment with your first project. ### 31.

Verdict: Unfashionable, quietly dependable, and priced in a way nothing else here is. Knack has been building database applications for fifteen years and it shows in both directions: the data modelling and role handling are solid and it stayed up through every one of our tests at 4.2 on reliability, but the interfaces look like 2016 and the AI assistance is the weakest in this cohort at 2.8. The fact we previously inverted is the one most likely to decide the purchase. Every Knack tier lists "Unlimited Users / Roles", and the vendor titles its own pricing page "Knack Pricing | Unlimited Users Allows You to Scale Without Fees". Knack charges on records, storage and features, and never on seats, on every tier. In an index where per-seat pricing is the norm, that is the single most decision-relevant thing about it. Two more corrections: Ecommerce Payments is a first-party Pro-tier feature, so it is not as unsuited to anything a customer touches as we implied, and custom domains are tier gated at one on Pro and three on Corporate, with none on the entry tier, so "paid plans" was never a useful qualifier when every Knack plan is paid. There is still no free tier, only a trial. Dissenting view: One panellist rated the design axis higher, arguing the theming options are better than the defaults suggest. The score reflects what a buyer gets without design work. Best for: Membership registers, applications and case management for organisations without engineers. Not for: Anything design-led, customer-facing, or expected to look current. Axis scores out of 5: - Reliability: 4.2 - Integrations: 3.5 - SEO and GEO: n/a, axis not applicable to this tool - Design quality: 2.9 - Agent performance: 2.8 - Speed: 3.4 - Value: 3.0 - Scalability: 3.6 - API and MCP access: 3.6 - Code ownership: 2.1 What works: - Unlimited users and roles on every tier. Knack charges on records, storage and features and never on seats, which is unique in this index - Data modelling and role permissions are genuinely mature - Stayed up through every brief we ran, scoring 4.2 on reliability - Ecommerce Payments is a first-party feature on the Pro tier What does not: - Interfaces look a decade out of date without significant theming work - Custom domains are tier gated: one on Pro, three on Corporate, none on the entry tier - Weakest AI assistance in the second cohort at 2.8 - No free tier, only a trial, and no code export Capability checks: - Full-stack backend: Yes - Database included: Yes, own store - Auth included: Yes, with unlimited users and roles on every tier - Code export: No, data export only - GitHub sync: No - One-click deploy: Yes - Custom domain: One on Pro, three on Corporate, none on the entry tier - Mobile or native output: Responsive web only - Team collaboration: Yes, and unlimited users and roles are included on every tier - Public API or MCP server: Yes, REST API - Self-hosting the output: No Pricing tiers: - Starter: USD 59 monthly. Core app, records allowance, unlimited users and roles A limited-time new-customer offer of USD 19 for the first three months was live in August 2026. - Pro: USD 130 monthly. More records, ecommerce payments, one custom domain, unlimited users and roles - Corporate: USD 300 monthly. Higher limits, priority support, more apps, three custom domains From USD 300. The vendor's footnote: starting price, final cost determined by usage requirements. - Enterprise: On request quote. Volume records, procurement, support terms FAQ: - Q: How does Knack charge? A: On records, storage and features, never on seats. Every tier lists unlimited users and roles, and the vendor titles its pricing page "Knack Pricing | Unlimited Users Allows You to Scale Without Fees". In a market that mostly bills per seat, that is the most decision-relevant fact about it. - Q: Does Knack have a free plan? A: No, only a trial. Paid plans list from USD 59 a month, which is worth knowing before you invest time in a build. - Q: Can Knack take payments? A: Yes. Ecommerce Payments is a first-party feature on the Pro tier. - Q: Is Knack good for customer-facing apps? A: Only if appearance does not matter: design scores 2.9, and the SEO and GEO axis is marked not applicable because Knack builds logged-in operational software rather than public crawlable pages. Custom domains are also gated, at one on Pro and three on Corporate. ### 32. Adalo - 3.2/5 - Slug: adalo - Official site: https://adalo.com - Category: mobile - Price from: USD 36 / month, billed annually (the vendor's own currency, not converted). Free tier: yes - Price note: Starter plan, billed annually. USD 45 billed monthly. Professional is USD 65 a month and Team is USD 200 a month. - Pricing model: Free plan to build and preview. Publishing from USD 45 a month on Starter, USD 36 billed annually, with Professional at USD 65 and Team at USD 200. - Star ratings counted: 15, community average 3.6/5 - Written reviews counted: 3 (a different number from the star ratings above) - Last verified: 2026-08-20T00:00:00.000Z - Review: https://www.app-builder-index.com/reviews/adalo - Spanish edition: https://www.app-builder-index.com/es/opiniones/adalo - Profile: https://www.app-builder-index.com/builders/adalo Summary: A drag-and-drop builder for mobile and web apps with its own database and app store publishing, still one of the gentlest introductions to building anything at all. Verdict: The kindest on-ramp in the index and no longer the right answer for most people. Adalo remains easy to learn and will genuinely get an app into the stores, and two facts in its favour deserve more prominence than we gave them: the database is a hosted PostgreSQL database, available on every tier including Free, and the vendor promises no usage or token-based charges on any tier, which is a real differentiator in a market that meters credits. Against that, performance is poor at 3.0, scalability at 2.8 is among the lowest here, there is no code export, and the App and Collections API is a Team-plan feature with no MCP server anywhere, so a bare yes on programmable access would mislead anyone pricing the cheaper plans. FlutterFlow now does more for less commitment. Dissenting view: One panellist argued Adalo deserves more credit for accessibility of the tool itself, since a large share of its users would never have shipped anything otherwise. Best for: First-time builders who want a phone app in the stores without learning a framework. Not for: Anything performance-sensitive, and anything you expect to grow. Axis scores out of 5: - Reliability: 3.6 - Integrations: 3.3 - SEO and GEO: n/a, axis not applicable to this tool - Design quality: 3.5 - Agent performance: 2.9 - Speed: 3.0 - Value: 3.4 - Scalability: 2.8 - API and MCP access: 2.6 - Code ownership: 2.0 What works: - Easiest tool in the index for a complete beginner to learn - Hosted PostgreSQL database on every tier including Free, with auth included - No usage or token-based charges on any tier, so the bill is the plan price - Real app store publishing without touching Xcode What does not: - Performance at 3.0 and scalability at 2.8 are both near the bottom - The App and Collections API is Team plan only, and there is no MCP server - No code export whatsoever - FlutterFlow does more for a similar or lower price Capability checks: - Full-stack backend: Yes - Database included: Yes, a hosted PostgreSQL database, on every tier including Free - Auth included: Yes - Code export: No - GitHub sync: No - One-click deploy: Yes, plus app store publishing - Custom domain: Yes, paid plans - Mobile or native output: Native iOS and Android builds - Team collaboration: Yes, paid plans - Public API or MCP server: App and Collections API on the Team plan only, and no MCP server - Self-hosting the output: No Pricing tiers: - Free: Free monthly. Build and preview, Adalo branding - Starter: USD 45 monthly. Publishing, custom domain, one app USD 36 billed annually. - Professional: USD 65 monthly. App store publishing, more apps, integrations - Team: USD 200 monthly. Collaborators, shared apps, higher limits FAQ: - Q: Is Adalo still worth using in 2026? A: Only for small, simple apps where ease of learning matters more than performance. FlutterFlow or Rork are better starting points for most projects now. - Q: What database does Adalo use? A: A hosted PostgreSQL database, included on every tier including Free, rather than a proprietary collection store. - Q: Does Adalo have an API? A: The App and Collections API is available on the Team plan only, and there is no MCP server, so treat programmable access as a higher-tier feature. - Q: Can you export an Adalo app? A: No. Code ownership scores 2.0, among the lowest in the index. ### 33. Thunkable - 3.1/5 - Slug: thunkable - Official site: https://thunkable.com - Category: mobile - Price from: USD 18 / month, billed yearly (the vendor's own currency, not converted). Free tier: yes - Price note: Accelerator plan, billed yearly. You cannot publish a live app below USD 37 a month (Builder, billed yearly), and even then only one. Unlimited live apps need the USD 99 Advanced plan. - Pricing model: Free plan with public projects: they sit in a public gallery for anyone to preview and remix. Accelerator is USD 18 a month billed yearly, but publishing a live app starts at USD 37 and unlimited live apps need USD 99. - Star ratings counted: 11, community average 3.7/5 - Written reviews counted: 2 (a different number from the star ratings above) - Last verified: 2026-08-20T00:00:00.000Z - Review: https://www.app-builder-index.com/reviews/thunkable - Spanish edition: https://www.app-builder-index.com/es/opiniones/thunkable - Profile: https://www.app-builder-index.com/builders/thunkable Summary: A block and drag-and-drop mobile app builder with native publishing, widely used in classrooms and by first-time builders who need something forgiving. Verdict: A teaching tool that is priced and gated like a production platform, and the gating is the story. You cannot publish a live app on the entry paid tier: live publishing starts at Builder and covers exactly one app, and unlimited live apps require Advanced. That makes the Free and Accelerator tiers evaluation-only, which is not how they read at a glance. Worse for anyone thinking long term, the vendor FAQ states that "you must maintain an active subscription for your published apps to remain active". Your shipped app is a rental. That is materially worse ownership than any code-exporting builder here and it is the whole explanation for the lowest code-ownership score in the index. Two more line items people miss: you still need paid Google and Apple developer licences, which are separate from the Thunkable subscription, and AI tokens expire at the end of every billing cycle rather than rolling over. As a way to teach app logic through drag-and-drop blocks, Thunkable remains genuinely good, and the classroom is where it belongs. Dissenting view: One panellist argued that education tools should be excluded from a buyer index rather than scored against commercial platforms they are not competing with. Best for: Education, prototypes and simple utility apps built by people learning to build at all. Not for: Commercial products, and anything with a serious data model. Axis scores out of 5: - Reliability: 3.7 - Integrations: 3.1 - SEO and GEO: n/a, axis not applicable to this tool - Design quality: 3.2 - Agent performance: 2.8 - Speed: 3.3 - Value: 2.7 - Scalability: 2.7 - API and MCP access: 2.9 - Code ownership: 1.8 What works: - Drag-and-drop block logic is the clearest way we have seen to teach how an app actually works - Genuine cross-platform output from a single project - Large library of classroom-ready examples What does not: - You cannot publish a live app on the entry paid tier. Live publishing starts at Builder with one app, and unlimited live apps need Advanced, so Free and Accelerator are evaluation-only - The vendor FAQ states you must maintain an active subscription for your published apps to remain active, so a lapsed payment takes your shipped app down - Paid Google and Apple developer licences are required and are separate from the subscription - AI tokens expire at the end of every billing cycle and do not roll over Capability checks: - Full-stack backend: Limited - Database included: Yes, simple data sources - Auth included: Yes, basic - Code export: No, and the vendor requires an active subscription for published apps to remain active - GitHub sync: No - One-click deploy: Live publishing starts at the Builder plan and covers one app, unlimited live apps require Advanced, and paid Google and Apple developer licences are required separately - Custom domain: Not applicable - Mobile or native output: Native iOS and Android builds - Team collaboration: Yes, paid plans - Public API or MCP server: Limited, REST blocks - Self-hosting the output: No Pricing tiers: - Free: Free monthly. Public projects in the gallery, anyone can preview and remix, Thunkable branding - Accelerator: USD 18 monthly, billed yearly. Private projects, more screens Cannot publish a live app. - Builder: USD 37 monthly, billed yearly. One live published app, store publishing - Advanced: USD 99 monthly. Unlimited live apps, higher limits, integrations FAQ: - Q: Can I publish an app on the cheapest paid plan? A: No. Live publishing starts at the Builder plan and covers one app. Unlimited live apps require Advanced. Free and Accelerator are evaluation tiers in practice. - Q: What happens to my published app if I stop paying? A: The vendor FAQ says you must maintain an active subscription for your published apps to remain active. There is no code export, so this is the weakest ownership position in the index and the reason for the lowest code-ownership score here. - Q: Are there costs beyond the subscription? A: Yes. Paid Google and Apple developer licences are required separately. AI tokens also expire at the end of each billing cycle rather than rolling over. ## Guides by use case - Best AI app builders for a SaaS MVP (2026): https://www.app-builder-index.com/best/saas-mvp (top picks: lovable, totalum, replit, v0, cursor, xano) - Best AI app builders for internal tools (2026): https://www.app-builder-index.com/best/internal-tools (top picks: base44, totalum, replit, retool, glide, softr, airtable) - Best AI app builders for mobile apps (2026): https://www.app-builder-index.com/best/mobile-apps (top picks: rocket-new, bolt-new, replit, lovable, flutterflow, rork, a0-dev, adalo) - Best AI app builders for agencies (2026): https://www.app-builder-index.com/best/agencies (top picks: lovable, v0, totalum, replit, weweb, plasmic, bubble, cursor) - Best AI app builders for ecommerce (2026): https://www.app-builder-index.com/best/ecommerce (top picks: lovable, totalum, base44, zite, bubble, xano) - Best AI app builders for SEO websites (2026): https://www.app-builder-index.com/best/seo-websites (top picks: v0, lovable, totalum, zite, readdy, weweb, plasmic, nordcraft) - Best AI app builders for building AI apps (2026): https://www.app-builder-index.com/best/ai-apps (top picks: replit, totalum, lovable, emergent, cursor, xano, manus) ## Head to head comparisons - lovable vs bolt-new: https://www.app-builder-index.com/compare/lovable-vs-bolt-new - lovable vs v0: https://www.app-builder-index.com/compare/lovable-vs-v0 - lovable vs replit: https://www.app-builder-index.com/compare/lovable-vs-replit - lovable vs base44: https://www.app-builder-index.com/compare/lovable-vs-base44 - lovable vs totalum: https://www.app-builder-index.com/compare/lovable-vs-totalum - v0 vs bolt-new: https://www.app-builder-index.com/compare/v0-vs-bolt-new - replit vs totalum: https://www.app-builder-index.com/compare/replit-vs-totalum - base44 vs totalum: https://www.app-builder-index.com/compare/base44-vs-totalum - zite vs trickle: https://www.app-builder-index.com/compare/zite-vs-trickle - emergent vs replit: https://www.app-builder-index.com/compare/emergent-vs-replit - rocket-new vs lovable: https://www.app-builder-index.com/compare/rocket-new-vs-lovable - cursor vs lovable: https://www.app-builder-index.com/compare/cursor-vs-lovable - cursor vs v0: https://www.app-builder-index.com/compare/cursor-vs-v0 - bubble vs lovable: https://www.app-builder-index.com/compare/bubble-vs-lovable - retool vs base44: https://www.app-builder-index.com/compare/retool-vs-base44 - glide vs retool: https://www.app-builder-index.com/compare/glide-vs-retool - softr vs glide: https://www.app-builder-index.com/compare/softr-vs-glide - airtable vs softr: https://www.app-builder-index.com/compare/airtable-vs-softr - knack vs airtable: https://www.app-builder-index.com/compare/knack-vs-airtable - xano vs totalum: https://www.app-builder-index.com/compare/xano-vs-totalum - weweb vs plasmic: https://www.app-builder-index.com/compare/weweb-vs-plasmic - nordcraft vs weweb: https://www.app-builder-index.com/compare/nordcraft-vs-weweb - readdy vs v0: https://www.app-builder-index.com/compare/readdy-vs-v0 - macaly vs lovable: https://www.app-builder-index.com/compare/macaly-vs-lovable - momen vs bubble: https://www.app-builder-index.com/compare/momen-vs-bubble - appmaster vs bubble: https://www.app-builder-index.com/compare/appmaster-vs-bubble - flutterflow vs adalo: https://www.app-builder-index.com/compare/flutterflow-vs-adalo - flutterflow vs rocket-new: https://www.app-builder-index.com/compare/flutterflow-vs-rocket-new - draftbit vs flutterflow: https://www.app-builder-index.com/compare/draftbit-vs-flutterflow - bravo-studio vs flutterflow: https://www.app-builder-index.com/compare/bravo-studio-vs-flutterflow - thunkable vs adalo: https://www.app-builder-index.com/compare/thunkable-vs-adalo - rork vs a0-dev: https://www.app-builder-index.com/compare/rork-vs-a0-dev - manus vs lovable: https://www.app-builder-index.com/compare/manus-vs-lovable ## Editorial - [news] Our reviewers appeared to have joined before this site launched (2026-09-06T10:15:00.000Z): https://www.app-builder-index.com/news/our-reviewers-appeared-to-have-joined-before-we-launched - How we review says App Builder Index launched in 2026.

Brief six in our testing exists because we kept finding the gap between the two. Here is what to check yourself. - [news] MCP support has quietly become a buying criterion (2026-08-20T05:45:00.000Z): https://www.app-builder-index.com/news/mcp-becomes-a-buying-criterion - A year ago programmable access was a developer nicety.
