SlowAPI is a rate limiting library for Starlette and FastAPI, adapted from flask-limiter and built on top of the limits package. It supports decorator-based limits on endpoints with redis, memcached, or in-memory backends for tracking.

Use cases

  • rate limit fastapi endpoints
  • throttle requests per minute in starlette
  • add 429 responses to my api
  • limit api usage with redis backend
  • apply shared rate limits across multiple routes
  • protect fastapi endpoints from abuse

When to choose

  • you use FastAPI or Starlette and need per-endpoint rate limiting
  • you want flask-limiter-style limits in an ASGI app
  • you need redis, memcached, or memory-backed limit tracking

When to avoid

  • you need websocket endpoint rate limiting
  • you use Django or Flask (use flask-limiter or django-ratelimit instead)
  • you need a fully async-native rate limiter without API change risk
