Mobile and desktop context
Device settings help explain the conditions of a test. Compare runs under consistent conditions instead of treating one score as a universal result.
Lab data, clearly labeled
A Lighthouse lab run is a controlled observation. It is not a field Core Web Vitals assessment of your actual visitors.
Current availability
Real mobile and desktop speed tests run in an isolated Chromium/Lighthouse worker. Full reports include audit evidence, resource waterfalls, transfer breakdowns and captured visual progress. No domain verification is needed. Free reports contain a summary.
