Distributed rate limiting and idempotency protection running on Cloudflare's global edge network. Block malicious traffic, prevent duplicate charges, and protect your infrastructure—all with sub-20ms latency.
Simulates a user accidentally double-clicking a payment button. The first request processes normally, but the duplicate is caught and returns the cached response without charging twice.
Simulates a bot sending 20 rapid requests to your API. The rate limiter allows legitimate traffic through while blocking the excess, protecting your servers from overload.
Measures real round-trip latency to Cloudflare's edge network. Requests are processed at the nearest edge location, keeping response times fast regardless of your location.
