Google PageSpeed Insights for one public URL: the Lighthouse scores (performance, seo, accessibility, best-practices), the lab Core Web Vitals (FCP, LCP, CLS, TBT, Speed Index), the CrUX field data when Google has it (LCP, INP, CLS), and the top five opportunities with estimated savings. Mobile by default. A run takes 10 to 40 seconds and is cached for an hour. Keyless calls share Google's quota, so a busy moment is a 503.Overview
