burntop is an open-source full-stack template made for apps that AI coding agents build. It gives you FastAPI, React 19 (TanStack Start), Tailwind 4, shadcn/ui and PostgreSQL 18, with session auth, Google OAuth, a reference CRUD feature and Docker Compose ready to run.
The difference is the guardrails. The template has only end-to-end tests: 161 backend tests against real Postgres and 42 Playwright tests against the full stack. 39 mocking libraries are banned, so a mock import fails the build. A route that no test calls, a page that no spec opens or a model without a migration also fails the run. A feature is done only when make ci passes, so the agent can't fake a green check.
It works with Claude Code, Cursor, Codex or any agent that reads AGENTS.md. Source: https://github.com/agusmdev/fullstack-ai-template
