How fast is your website, really?
Enter a URL and we load your page in a real browser, up to eight times: three cold runs each on emulated mobile and desktop, plus a repeat visit per profile. You get Core Web Vitals, page weight, third-party cost, and the fixes, worst first.
Loads the page up to eight times in a real browser; slow pages shorten the run budget. Usually 30 to 60 seconds. Nothing stored.
What this measures
Real browser, real loads
No estimates: headless Chromium loads your page cold, three runs per profile, and the report shows the median.
Core Web Vitals
LCP, CLS, and total blocking time, measured the way Google defines them, against the official thresholds.
Mobile and desktop
Mobile runs on an emulated 9 Mbit/s connection with a 4× slower CPU, because that is where pages actually fail.
Where the bytes go
Page weight, request count, and which third-party scripts cost the most, plus the concrete fix for each finding.
Slow pages lose leads
We fix performance at the source: caching and server setup, image pipelines, third-party cleanup, and frontends that pass Core Web Vitals.
