Our assessment in one line
Not really an app builder, and better for it. Marblism scaffolds a conventional Next.js and Prisma repository with auth and billing already in place, hands you the whole thing, and expects you to run it. Code ownership at 4.7 is the highest mark in the index. Everything downstream of generation is on you: our test builds needed manual fixes in five of six briefs, and there is no iterative agent to lean on. Excellent time saver for a developer. Useless without one.
