FastSaaS
A FastAPI + Postgres SaaS starter with Stripe billing and team roles baked in
- Best for
- Python/FastAPI developers who want a production-ready SaaS backend with Stripe billing and multi-tenant teams without touching a Node.js stack.
- Skip if
- You want a Next.js/React frontend included out of the box, or you need a free/open-source option.
FastSaaS is a one-time-purchase SaaS boilerplate built on FastAPI and PostgreSQL. It ships email/password and Google OAuth auth, multi-tenant team management with role-based permissions, Stripe subscription billing with invoicing, automated email workflows, and a Docker/CI-ready deployment setup. It's aimed at developers who want a Python backend rather than the more common Next.js starters.
Pros

Cons
