Ping & Latency Tester
Measure TCP connect latency from the server or HTTPS timing from your browser—clearly labeled, never fake ICMP from the browser.
Configure target and start a test to see latency metrics.
How to use
- Enter a public hostname.
- Choose measurement mode and probe count, then Start Test.
- Read latency, jitter, and failure counts on the chart.
Examples
Compare CDN host
Run server TCP probes against your API hostname to see connect-time variation.
Browser path
Use browser HTTPS timing to approximate client-to-site load latency for CORS-accessible URLs.
Internal and private targets are blocked. Maximum 20 probes per run. Server mode uses TCP port 443 (fallback 80).
FAQ
- Is this ICMP?
- Server mode uses TCP connect time. Browser mode uses fetch timing. Neither claims to be ICMP from your laptop.
- Why are some hosts blocked?
- SSRF protections block private, loopback, and metadata destinations.
