What the scan checks
One scan. The full speed picture.
Lab scores alone do not explain a slow site. The report ties your numbers to the things that cause them.
Google Lighthouse
A real Lighthouse run on mobile and desktop, with the performance score Google reports.
Core Web Vitals
LCP, layout shift and the other metrics that decide how your pages feel to real visitors.
Server response
How long your origin takes to answer, so a slow host shows up as a slow host.
Cache detection
Whether page caching is actually working, or every visit is rebuilt from scratch.
Asset analysis
Render-blocking scripts, heavy CSS and oversized images, the usual reasons scores drop.
Shareable report
Every scan gets its own report page, so you can send it to a client or a developer.
