AutoBuilder is an agentic scaffolding tool that takes a natural-language product spec and produces a working full-stack application — schema, API routes, UI, and tests included. Describe what you want in a paragraph, and a Claude-powered agent plans, generates, and verifies the code in an isolated sandbox.
Each run executes inside a Vercel Sandbox so generated code can be installed, type-checked, and tested before it ever touches your repo. The agent iterates on failures automatically until the build is green.
Founders use AutoBuilder to skip the boring scaffolding phase and start with a solid foundation they can immediately customize.
