FastAPI-boilerplate (Fastro)

Async FastAPI backend starter with auth, caching, rate-limits and background jobs

Best for: Teams who want a clean, hackable async FastAPI backend with auth, jobs, and caching already wired, without paying for a full SaaS bundle.
Skip if: You need Stripe billing, entitlements, or a bundled frontend out of the box - that's the paid FastroAI tier, not this repo.

Fastro is Benav Labs' open-source FastAPI foundation built on SQLAlchemy 2.0 and Pydantic v2. It ships server-side session auth with OAuth and API keys, FastCRUD-powered generics, a SQLAdmin panel, Taskiq background workers, and Redis/Memcached caching, all wired through a plugin-ready CLI for compose scaffolding and env audits. A paid sibling product, FastroAI, layers Stripe billing and an AI agent stack on top for teams that want a complete SaaS rather than just the backend foundation.

Pros

Fully async stack (FastAPI + SQLAlchemy 2.0 + Pydantic v2) with sensible, opt-out defaults
Background jobs (Taskiq), caching, and per-tier rate limiting included, not bolted on
Actively maintained with 2000+ GitHub stars and a plugin-ready CLI for scaffolding
