What It Does

  • Three implementation methods: middleware (global), decorator (per route), dependency injection
  • Sliding Window, Token Bucket, and Fixed Window rate limiting algorithms
  • Redis support with automatic in-memory fallback when Redis is unavailable
  • Scoped rate limiters for applying different limits to endpoint groups
  • Fingerprint levels (RELAXED, NORMAL, STRICT) for client identification granularity
  • Multiple stacking rules where the most restrictive limit applies

Quick Start

uv add fastapi-420

from fastapi import FastAPI
from fastapi_420 import RateLimiter, RateLimiterSettings

app = FastAPI()
limiter = RateLimiter(RateLimiterSettings(default_limit="69/minute"))
app.add_middleware(limiter.middleware)

For Redis support: uv add fastapi-420[redis]
