Rate limiting for go-redis

A rate-limiting library for Rust (f.k.a. ratelimit_meter)

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

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

Rate limiting based on Generic Cell Rate Algorithm

RateLimiter helps to prevent abuse by limiting the number of requests that could be me made consequentially.

Rate limiting with few algorithms

fiber_limiter using redis as store for rate limit with two algorithms for choosing sliding window, gcra leaky bucket

Exq Rate Limiter

High-performance GCRA rate limiter. Multi-protocol server (HTTP, gRPC, Redis/RESP) with advanced metrics, or embed as a minimal Rust library. Self-tuning memory management 🦀

Advanced rate limiting library for Ruby. Rate limit anything - API calls, AI requests, background jobs. Features GCRA, token bucket algorithms, circuit breakers, and multiple storage backends.

echo_limiter using redis as store for rate limit with two algorithms for choosing sliding window, gcra leaky bucket

http_limiter using redis as store for rate limit with two algorithms for choosing sliding window, gcra leaky bucket

A rate limiter for Zig. Implements the GCRA (Generic Cell Rate Algorithm) with a Token-Bucket-like API.

Rate limiting for Node and the web: GCRA-default, one transform across in-memory/Redis/Postgres (proven bit-identical), and two-tier token leasing with a formally-verified overshoot bound independent of fleet size. Sync API, multi-dimensional checks, fixed-memory DDoS sketches.

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.

Resilient, high-performance distributed rate limiter library for Go and Redis. Features 5 algorithms (GCRA, Token Bucket, Sliding Window) with automatic thread-safe local in-memory fallback on Redis outages. Includes Gin, Echo, net/http middleware and an interactive CLI simulator dashboard.

A generic cell rate algorithm based rate limiter

Declarative rate limiting for Node.js

Simulate rate limiting algorithms - fixed window, sliding log, sliding counter, token bucket, GCRA, concurrency and distributed multi-node counters - against synthetic or recorded traffic, and compare accept rates, burst behaviour, per-tenant fairness and overshoot before choosing a limit.
