Rocket.new Review (2026)

A builder that treats mobile as a first-class output, generating Flutter and React Native alongside a web target from the same prompt.

The quick answer

Assessed for 2026

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 the weakest here, and the credit model prices exploration higher than it should.

The 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.

One member of the panel disagreed with the consensus. We publish the disagreement rather than average it away.

  1. Editor panel

    Got us into both app stores without a mobile developer

    Isabel Moreno@isabelmoreno

    Founder, fitness app.

    We had a web product and needed iOS and Android. Rocket produced a Flutter app that we submitted with modest hand editing. A mobile contractor quoted us eleven thousand euros for the same milestone. Four stars, held back by how often I had to regenerate screens.

    Pros
    Actual store-ready mobile builds. Saved a five figure contract.
    Cons
    Frequent regenerations, each one costing credits.

  2. Editor panel

    Real mobile output, shaky everything else

    Tom Brackett@tbrackett

    Testing lead. Maintains the fixed brief harness and the reproducible build logs behind every score.

    On the mobile brief Rocket.new produced Flutter and React Native targets whose navigation followed platform conventions rather than looking like a wrapped web page, which nothing else here managed. On the other five briefs it needed more regenerations per finished screen than Lovable or Base44, and our SEO axis measurement of 3.0 is the lowest in the index. One panellist argues our weights are unfair to a mobile tool. He is partly right, and the objection is published on this page rather than filed away.

    Pros
    Genuine native-feeling mobile output. Two mobile frameworks from one brief.
    Cons
    Most regenerations per finished screen among mid-priced tools. Lowest SEO score here.

  3. Editor panel

    Good scaffolding, average code

    Dmitri Volkov@dvolkov

    React Native developer.

    The navigation structure and screen layout it produces are a reasonable starting point. The state management is naive and I rewrote it. As a scaffolding tool, useful. As a replacement for a mobile engineer, no, and I am not sure it claims to be.

    Pros
    Sensible navigation scaffolding.
    Cons
    State management needs rewriting.

  4. Editor panel

    Fine for the app, useless for the website

    Nora Fitzgerald@norafitz

    Product owner, retail.

    Our companion website built here was poor: slow, thin markup, no control over metadata. We moved that half to another tool and kept Rocket for the app. Worth knowing before you commit both sides of a project to it.

    Pros
    The mobile half is genuinely good.
    Cons
    Web output is the weakest part of the product.

  5. Editor panel

    The only one we can sell a mobile project on

    Carlos Estevez@cestevez

    Agency owner, five staff.

    Clients ask for apps. Before Rocket we said no or subcontracted. Now we quote. The reliability is not where I want it, so we pad estimates, but the business case is clear.

    Pros
    Opens up mobile work for small agencies.
    Cons
    Padding estimates for reliability is still necessary.

Frequently asked

Is Rocket.new the best AI builder for mobile apps?
In this index, yes, it is the strongest mobile-first option. It generates Flutter and React Native targets and the screens follow platform conventions rather than looking like a wrapped website.
Why is Rocket.new's overall score mid-table?
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.
Can you export the code?
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.
What is the biggest risk?
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.
