fastify/fastify-rate-limit

The fastify-rate-limit project provides a low-overhead rate limiter plugin for Fastify routes, designed to prevent abuse by limiting the number of requests from a single client within a specified time window. It supports in-memory and Redis-based storage, customizable rate limits per route, and various configuration options for headers, error responses, and callback hooks. This plugin is ideal for developers using Fastify who need to protect their APIs from excessive traffic and ensure fair usage.
