burntop

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 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, and a route that no test calls fails the build, so the agent can't fake a green check. Works with Claude Code, Cursor, Codex or any agent that reads AGENTS.md.
