Website Ping Test
Measure HTTP response time of any site with repeated rounds
Runs 100% in your browser — nothing is ever uploaded.
What is Website Ping Test?
Check how fast a website responds right from your browser: enter a URL, choose the number of rounds, and the tool fires timed HTTP requests, reporting each round plus min / average / max and jitter. Note this measures HTTP fetch timing from your device — not ICMP ping — so it includes DNS, TLS and server time: exactly what your visitors actually experience.
How to use Website Ping Test
- Enter the website URL (https://…).
- Choose the number of rounds (5–20) and start the test.
- Watch per-round timings appear live with a mini bar chart.
- Read the summary: min, average, max and jitter in milliseconds.
NetScope FAQ
Is this a real ICMP ping?
No — browsers cannot send raw ICMP packets. The tool measures HTTP request timing instead, which includes DNS lookup, TLS handshake and server response. That is arguably more useful: it reflects the latency real users experience when loading the site.
Why do some sites show "opaque" results?
Cross-origin sites without CORS headers return opaque responses: the browser still times the full round-trip (which is what matters) but hides the HTTP status code. The measured latency remains accurate.
Is any data about my tests stored?
No. Requests go directly from your browser to the target site; we never see the URLs you test and results are never uploaded or logged anywhere.
Are these network tools free?
Yes — every NetScope tool is 100% free with no signup, no limits and no ads walls.
Is my data uploaded anywhere?
No. All calculations (CIDR math, URL parsing, UTM building) run entirely in your browser. Nothing ever leaves your device.
Do these tools work offline?
Yes — once the page is loaded, the calculators work without an internet connection.
Can I use NetScope on private or internal addresses?
Yes, and that is the main reason it exists. Subnet, binary and URL tools are pure calculation, so RFC 1918 ranges like 10.0.0.0/8 or 192.168.1.0/24, internal hostnames and staging URLs are handled exactly like public ones — and never leave your browser. The ping and WebSocket testers are the one exception: they open a real connection, so they only reach hosts your own machine can already reach.
How accurate is the ping test compared with the ping command?
It measures something slightly different. A terminal ping sends ICMP packets, which browsers cannot emit, so NetScope times an HTTP request instead. The result therefore includes DNS resolution, the TLS handshake and the server’s own response time, and reads higher than ICMP. That makes it a good proxy for what a visitor experiences, but not a substitute for ICMP when you are diagnosing packet loss.
Do I need to install anything or sign in?
No. Every NetScope tool is plain JavaScript served with the page — no account, no extension, no CLI. Bookmark the tool you use most and it opens ready to work, on a phone, a locked-down work laptop or a machine where you cannot install software.
