asyncio-throttle

Simple, easy-to-use throttler for asyncio.

throttler

🔀⏳ Easy throttling with asyncio support

rush

Modular, way of implementing rate-limiting in python with a few handy default implementations

mthrottle

A simple and generic rate limiter to prevent too many function calls or http requests.

plimit

Run multiple async functions with limited concurrency — Python port of p-limit

python-throttle

Super naive python redis limiter

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.

hawkapi-ratelimit

Rate limiting for HawkAPI — token bucket + sliding window, Redis + in-memory backends

cpulimiter

A Python library for Windows to programmatically limit the CPU usage of running processes

webtool

FastAPI/Starlette library for authentication, throttling, caching.

aiothrottles

Throttles for Python coroutines.

ratelimit-io

Flexible bidirectional rate-limiting library with redis backend

rate-control

Versatile rate controlling in Python

django-gradual-throttle

🕒 A Django middleware for graceful request throttling with configurable delay strategies (linear, exponential, or custom). Unlike traditional rate limiting that blocks excessive traffic, this package introduces progressive delays to throttle requests smartly and smoothly.

socket-throttle

Wrapper for sockets letting you limit send/recv bandwidth

agentprod

Production patterns for indie AI agents — token bucket, cost-aware routing, retry, observability.

tasklane

Bounded-concurrency async for Python: run, map, and stream awaitables with limits, retries, rate limiting, and progress — in one typed call.
