About This Tool

The Response Time Checker measures the time-to-first-byte (TTFB) for any URL — showing how quickly the server responds to an HTTP request. TTFB is a key performance indicator and a ranking signal for Google. Enter a URL and get the response time in milliseconds. Free, no account needed.

How to Use

  1. 1

    Enter the full URL you want to test.

  2. 2

    Click Test — the response time in milliseconds appears within seconds.

  3. 3

    Compare against the recommended TTFB of under 200ms for optimal performance.
