About ByteCheck

ByteCheck is a minimal web tool that measures Time To First Byte (TTFB) for a given URL: the time from the browser making an HTTP request to the first byte coming back from the server. It is a useful indicator of how responsive a web server and the network resources behind a site are.

It does not audit the full page load, which keeps it quick and repeatable. It suits developers and administrators checking server response times after changes to hosting or caching.

Strengths

  • Focused TTFB measurement
  • Quick and repeatable
  • No installation needed

Limitations

  • Measures server response only, not full page load
  • Only tests publicly reachable URLs
