Free PageSpeed Insights checker. Run Google Lighthouse on any URL for performance, accessibility, SEO and best-practice scores, Core Web Vitals and CrUX field data.
About the PageSpeed Insights Checker
Lab data (Lighthouse) shows what's slow on a simulated device; field data (CrUX) shows what real Chrome users experienced over 28 days. Core Web Vitals are a ranking signal, so LCP under 2.5 s and INP under 200 ms matter.
