How this is measured
Each site's home page is tested with Google PageSpeed Insights (Lighthouse, simulated mid-range phone on a slow 4G connection) when it's enriched; real-user ratings come from the Chrome UX Report where Google has enough visits. Only sites in the Tranco top million are named. See also websites using Netlify. Updated October 2026.
