Client Ping

Measure client-side latency using image/fetch requests
This free online client ping runs in your browser and is part of our Developer Tools collection.

Client-side Ping

Measures round-trip time from the browser to a host using image or fetch requests. This tests client network latency (subject to CORS and resource availability).

How it works

  • Image: Loads /favicon.ico on the target origin and measures load time. No response body access required.
  • Fetch: Sends a fetch with mode: 'no-cors' and measures timing. Response is opaque but latency is measurable.
  • Results depend on the target serving the requested resource and browser/network conditions.
