# Rate Limit Generator Rate limiting is essential but the config is fiddly. Describe your limits in plain English and get working configuration. **One command. Zero config. Just works.** ## Quick Start ```bash npx ai-rate-limit "100 requests per minute per IP" ``` ## What It Does - Generates rate limit configuration - Supports IP, user, and API key based limiting - Includes sliding window and fixed window options - Works with Express, Fastify, and more ## Usage Examples ```bash # Basic IP rate limiting npx ai-rate-limit "100 requests per minute per IP" # Login protection npx ai-rate-limit "10 login attempts per hour, block for 30 min" # API tier limits npx ai-rate-limit "free tier 100/day, pro 10000/day" ``` ## Best Practices - **Return headers** - let clients know their quota - **Use sliding windows** - smoother than fixed - **Have escape hatches** - allow bursts for legitimate use - **Log rate limit hits** - detect abuse patterns ## When to Use This - Protecting API from abuse - Implementing usage tiers - Preventing brute force attacks - Adding fair use policies ## Part of the LXGIC Dev Toolkit This is one of 110+ free developer tools built by LXGIC Studios.
