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

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-sliding-window

sliding window rate limiter for FastAPI

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.

flowguard-core

High-performance Async Rate Limiting, Circuit Breaking & Resilience Orchestration for LLM & API Pipelines.

pygolem

Spawn tiny little servants, running things in parallel.

fastapi-gradual-throttle

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

limifyrate

Redis-backed, async-first, framework-agnostic rate limiting engine for Python.

ratelink

A production-grade rate limiter module with 5+ algorithms (Token Bucket, Sliding Window, Leaky Bucket, etc.) with multi-backend support (Redis, memory, distributed).

larzlimit

Rate limiting in pure Python: token bucket, sliding & fixed window, per-key, with a decorator and WSGI middleware. Zero dependencies.

edging

Rate limiting that approaches but never exceeds a threshold.

throttlepy

Token bucket and sliding window rate limiting for Python. In-memory or Redis. Sync and async.
