Website Speed Test | Dodolytics

Enter a URL to measure how fast it responds: latency (time to first byte) and total time to download the page, redirects included. Any URL can be tested, not just a tracked Dodolytics website. Free tool, nothing you test is stored; results are shown once and not saved.

Two honest limitations, not glossed over: this measures the page's own HTML response, not a full rendered-page load (images, CSS, JS, and on-screen render time aren't included, since this app has no headless browser to measure that with); and the test runs from this app's own server, not from your location or several regions the way some commercial speed-test tools do.

What is a website speed test tool?

A website speed test tool measures how fast a URL actually responds — how long the server takes to send back its first byte (latency), and how long the full response takes to download, including any redirects along the way. It gives you real, measured numbers instead of guessing whether a page "feels slow."

How do I use it?

Enter a URL above. This tool fetches it and times the whole request from start to finish, following each redirect hop along the way. Results show latency (time to first byte), total load time, response size, and a full DNS/connect/TLS- handshake/server-response breakdown for the page actually tested, plus a redirect-hop table when more than one hop occurred. It honestly measures only the page's own HTML response, not a full rendered page — images, CSS, and JS aren't included, since this app has no headless browser to measure that with — and the test runs from this app's own server, not from your location or several regions the way some commercial speed-test tools do.

Why is it useful?

A slow server response hurts both visitor experience and SEO — search engines factor page speed into ranking.
Quickly spots a redirect chain silently adding latency to every single visit to a page.
Useful right after a hosting or CDN change, a DNS migration, or general performance tuning — a real before-and-after measurement, not a guess.
Free, no sign-up required, and nothing about a test is stored — test any URL, not just a site you already track.
