A developer shared three patterns for implementing rate limiting in serverless applications without relying on Redis. The first pattern uses durable objects, like Cloudflare Workers' Durable Objects, to maintain exact counts for metered services, offering correctness at a small per-request cost. The second pattern involves edge configuration token buckets, which trade precision for very low latency, suitable for less strict throttling needs. The third pattern utilizes signed-window limits, requiring no external storage and proving effective for basic abuse prevention at small scales. AI
