The public URL, domain, IP address, record type, or audit option requested by the checker.
A speed test is a snapshot for one URL, device profile and test location. Network conditions, caches, consent banners and third-party scripts can change results between runs.
The public URL, domain, IP address, record type, or audit option requested by the checker.
A point-in-time observation from the public target and the checks available on this page.
A practical way to use it is to run a fresh diagnostic after a hosting, DNS, certificate, redirect, content or performance change. Start with a representative input, inspect the first result, then adjust one setting at a time if you need a different outcome.
The checker uses the public target you enter to make a diagnostic request. Do not place credentials or private access tokens in a URL.
Check HTTP status codes and server responses.
CheckVerify SSL certificate validity and expiry date.
CheckFind DNS records for any domain name.
LookupTrace URL redirects and final destination.
TraceCheck domain registration and expiry dates.
CheckEnter the website URL you want to test.
We analyze your page performance and speed.
View detailed metrics and performance score.
Follow recommendations to improve your site.

The page may show clearly labelled live server or page diagnostics instead. It does not invent Lighthouse or Core Web Vitals measurements.
No — only publicly accessible pages can be tested.
After major changes, or once a month for ongoing monitoring.
