A TypeScript rate limiting library backed by Upstash Redis that works over HTTP, making it suitable for serverless and edge runtimes. It provides sliding window, fixed window, token bucket, and other limiting algorithms with optional analytics.

Use cases

• rate limit api requests in serverless functions
• add rate limiting to next.js app
• limit requests per ip in cloudflare workers
• sliding window rate limiter with redis
• protect expensive endpoints from abuse
• rate limiting on vercel edge functions

When to choose

• you need connectionless HTTP-based rate limiting in serverless or edge environments
• you already use Upstash Redis
• you want built-in analytics and multiple window algorithms

When to avoid

• you want rate limiting without an external Redis dependency
• you need TCP-based Redis with a self-hosted instance and low latency
• you are not on a JavaScript/TypeScript runtime
