Fastapi Backend Template
This is a solid starting point if you're spinning up a new FastAPI project and don't want to wire up the database layer from scratch. It comes with async SQLAlchemy 2.0, Alembic migrations, and PostgreSQL already configured, plus Docker support for deployment. The tech choices are modern and the async setup is done right, which saves you from the usual boilerplate headaches. Best for greenfield projects where you want production-ready patterns but still need flexibility to build your own business logic. If you're already deep into a different stack or need something more opinionated about auth and API structure, you might want to keep looking.
