Frequently Asked Questions

Which rate limiting algorithm should I choose?
Token bucket is best for APIs that need to handle bursts, leaky bucket for smooth traffic, fixed window for simplicity, sliding window for more accurate limiting, and sliding log for precise control.
How do I handle distributed rate limiting?
Use Redis or similar distributed storage to maintain rate limit counters across multiple servers. The tool generates Redis Lua scripts for atomic operations.
What headers should I include in rate limited responses?
Include X-RateLimit-Limit, X-RateLimit-Remaining, X-RateLimit-Reset, and Retry-After headers to help clients implement proper backoff strategies.
How do I test my rate limiting implementation?
Use the generated testing scenarios to validate normal traffic, burst handling, sustained overload, and recovery behavior.
What monitoring should I implement?
Monitor rate limit hit rates, algorithm performance, request patterns, and set up alerts for unusual traffic or high hit rates.
