Rate Limit Detector

Check if a website has rate limiting configured on its endpoints

What is Rate Limiting?

Rate limiting controls how many requests a client can make to a server within a given time window. It's a critical defense against brute-force attacks, API abuse, DDoS, and credential stuffing.

This tool checks for standard RateLimit-* headers (IETF draft), vendor-specificX-RateLimit-* headers, and Retry-After across common endpoints.

Standard Headers
RateLimit-Limit, RateLimit-Remaining, RateLimit-Reset, RateLimit-Policy
Vendor Headers
X-RateLimit-Limit, X-RateLimit-Remaining, X-Rate-Limit
