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.

How to Use the Online Client Ping

1 Inspect Test Endpoints

Review the list of global CDN endpoints and major cloud edge locations.

2 Initiate Browser-Side Ping Test

Click "Start Test" to measure latency directly from your device using fetch/image timing probes.

3 Observe Real-Time Jitter & Latency

Watch the animated ping gauge measure your immediate network latency and jitter variation.

4 Compare Global Edge Regions

Inspect which cloud regions (US East, US West, Europe, Asia, India) deliver the lowest round-trip times from your current location.

Frequently Asked Questions

Common questions about using this free online client ping.

How does in-browser Client Ping work without ICMP permissions? ▾
Standard web browsers restrict raw socket ICMP access for security. Client Ping uses high-resolution `performance.now()` timing around lightweight HTTP HEAD or cached image asset requests to measure true application-layer latency.
What is Jitter in a network test? ▾
Jitter is the statistical variation in latency over consecutive packet tests. Low jitter (under 5ms) indicates a stable connection; high jitter causes buffering in streaming video and stutter in voice calls.
Why does Client Ping reflect my real-world internet speed more accurately? ▾
Because the test originates from your actual browser and local Wi-Fi/cellular connection, capturing real Wi-Fi interference, ISP congestion, and local network hops.
Can I run this test on mobile phones? ▾
Yes. Client Ping is fully responsive and runs smoothly across iOS and Android mobile browsers.
