About the Website Speed Checker
Measure a page's server-side fetch time and download size. An honest network timing check — not a Lighthouse/Core Web Vitals audit.
The Website Speed Checker is part of the Website Tools collection on Tool Magic Lab. Check headers, redirects, canonical tags and page metadata for any public URL.
This tool fetches the live URL you enter from our server, with SSRF protection, rate limits and timeouts, and reports exactly what it found — including when a site blocks automated checks.
