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, 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. It works with Claude Code, Cursor, Codex or any agent that reads AGENTS.md.

Features: FastAPI + SQLAlchemy 2 async + Alembic + Pydantic 2 backend. React 19 + TanStack Start/Router/Query + Tailwind 4 + shadcn/ui frontend. Session auth, Google OAuth, password reset, email verification, Argon2. 203 end-to-end tests (161 backend on real Postgres, 42 Playwright). 39 mocking libraries banned; untested routes and pages fail CI. AGENTS.md files and skills for Claude Code, Cursor and Codex. Docker Compose, GitHub Actions, Sentry, about 60 make targets. Use cases: start a new SaaS or internal tool with an AI coding agent without it faking tests; give Claude Code, Cursor or Codex a codebase with strict, enforced standards; learn a production FastAPI + React architecture. Start with one prompt: Create a new project from https://github.com/agusmdev/fullstack-ai-template as described in its README, then open AGENTS.md and follow it.
