Free PageSpeed Checker with Core Web Vitals and Real-User Data
Mobile and desktop Lighthouse scores, Core Web Vitals and the top fixes for any public URL, powered by the Google PageSpeed Insights API.
Speed advice is easy to find and hard to prioritise. A report with 40 findings does not tell you which three matter.
Slow pages lose visitors, and slow servers make every crawler's job harder. We show the scores and the two or three fixes with the biggest effect.
How to use it
- Enter a public URL.
- We run PageSpeed Insights for mobile and desktop.
- Start with the checks marked fix, then open the opportunities list.
What the checks mean
- Performance score. 90 and above is good. Under 50 is poor.
- LCP, CLS, TBT. Largest Contentful Paint, Cumulative Layout Shift and Total Blocking Time, checked against Google's thresholds.
- Field data. Real Chrome user measurements over 28 days, shown only when Google has enough visits to the URL.
Lab scores move a few points between runs. We cache each result for 24 hours so repeat checks stay consistent. The page must be public and cannot sit behind a login.
