Ping & Latency Checker
Check website latency and response time. Measure ping to any URL.
ping/curl.About Ping & Latency Checker
Measure the response time (latency) of any publicly accessible URL by timing fetch() requests from your browser. Run multiple ping attempts to see min, max, and average latency. Shows HTTP status code and response size for each ping. Useful for checking CDN response times, comparing API endpoint latency, testing if a server is reachable, and getting a rough baseline for web performance.
All processing happens entirely in your browser using modern web APIs. Nothing is uploaded to our servers — your data stays local and private. Free to use forever.
Common use cases
- Checking whether a website or API is currently reachable and responding
- Comparing response times of different CDN regions or endpoint locations
- Getting a rough latency baseline for an API before performance testing
- Verifying that a freshly deployed server is responding correctly
- Checking response times from your current network location
How it works
Uses the Fetch API with performance.now() to measure the time from request start to first byte received. The URL must have CORS headers that allow cross-origin requests (or you can use a CORS proxy). Each ping creates a fresh fetch() request with cache disabled (Cache-Control: no-cache) to avoid cached responses skewing the results.
