WebSpeed — page speed, original vs. Fast

Measure the open page with PageSpeed Insights and compare it with its copy sped up by WebSpeed Fast.

WebSpeed shows how fast the site in your current tab is, measured with Google PageSpeed Insights twice: the page as it is, and a copy of it served through WebSpeed Fast, our optimizing proxy. Both runs cover mobile and desktop, so you see in measured numbers what an acceleration layer changes on this page. Click the toolbar icon on any public site. If its home page was measured before, the result shows at once. If not, press "Measure the home page", or switch to the open page with "Check this page". A new measurement usually takes 2–5 minutes. You can close the window: the measurement keeps going, and the result appears as a badge on the toolbar icon. The result shows: • PageSpeed scores for the original page and the WebSpeed Fast copy, on mobile and desktop; • how much faster the page renders (Speed Index) and how much lighter it gets; • what WebSpeed Fast handled automatically; • what still slows the page down and needs changes on the site, with Lighthouse savings estimates. Numbers pass a verification step before they are shown. If the copy was not faster, or the measurement cannot support a comparison, WebSpeed says so and shows no speed-up figures. Optionally, the extension can highlight sites that already have a WebSpeed report. This is off until you turn it on. The check runs on your device against a list of hashed domain names downloaded once a day; the addresses of your tabs are not sent anywhere. Each measurement is published as a public report on webspeed.pro. Only public pages can be measured, and new measurements are limited to three a day. No account is needed.
