kbarbel640-del 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
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
# 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
