Rolling rate limit in redis via a lua script

Middleware that adds [Token Bucket]-style ratelimiting to [Spife].

A distributed token bucket using Redis as the coordinator. Useful as a rate limiter.

Zero-dependency token bucket rate limiter for browser and Node.js

Unopinionated promise limiters: concurrency, rate, interval, token bucket, capacity, debounce

Redis rate limiting with fixed window, sliding window, and token bucket algorithms

Token bucket and sliding window rate limiter for JavaScript/TypeScript

Distributed rate limiter with Token Bucket, Fixed Window, and Sliding Window algorithms. Redis and in-memory backends. Express, Fastify, and Hono middleware included.

Rate limiting (fixed / sliding / token-bucket)

Framework-agnostic rate limiting — fixed-window, sliding-window (log & weighted counter), token-bucket and leaky-bucket over a pluggable store, with composite/per-route limiters, cost-weighted requests, an injectable clock and standard RateLimit-*/X-RateL

promise-based token bucket filter for js/node

High-performance rate limiting with multiple algorithms (token bucket, sliding window) and storage backends (memory, Redis, database)

A simple, lightweight token bucket rate limiter for TypeScript/JavaScript.

A Token-Bucket Rate Limiter library for Node.js

IP based token bucket rate limiter / throttler.

Throttle-Box — a framework-agnostic token bucket API rate limiter for Express, Fastify, Koa and NestJS. Zero runtime dependencies, pluggable store.

Redis-backed distributed rate limiting with token bucket, sliding window, and leaky bucket algorithms

A continuously refilling token bucket for burst-aware limiting.

Token-bucket rate limiter — per-key limiting for APIs, jobs, or LLM calls, with a pluggable clock for deterministic tests.

**Red Bucket** is an implementation of the [**token bucket**](https://en.wikipedia.org/wiki/Token_bucket) algorithm using **Redis** as storage for the buckets.
