Token Bucket Python Packages

throttled-py

🔧 High-performance Python rate limiting library with multiple algorithms (Fixed Window, Sliding Window, Token Bucket, Leaky Bucket & GCRA) and storage backends (Redis, In-Memory).

limiter

⏲️ Easy rate limiting for Python using a token bucket algorithm, with async and thread-safe decorators and context managers

throttlekit-py

Python client for ThrottleKit — distributed rate limiting against one Node core via gRPC (full check/peek/forecast) or direct Redis (the core's own Lua, bit-identical). Conformance-proven on shared golden vectors.

adaptive-rate-limiter

Provider-agnostic adaptive rate limiting for AI/ML APIs with intelligent scheduling, streaming support, and distributed backends

easylimit

A simple, precise Python rate limiter with built-in context manager support for hassle-free API throttling

rate-control

Versatile rate controlling in Python

fastapi-gradual-throttle

FastAPI middleware for intelligent rate limiting and progressive request throttling — supports gradual delays, strict 429 limits, and Redis-backed scaling.

limifyrate

Framework-agnostic, Redis-backed rate limiting engine for modern async Python systems.

ratelink

Production-ready rate limiting library for Python with multiple algorithms, backends, and framework integrations
