Google PageSpeed Insights (PSI) provides the performance information of a given URL and advice on how to improve it.
PSI includes both lab data (via Lighthouse) and field data from the Chrome User Experience Report (CrUX) dataset. The performance score displayed at the top of the report is based on lab data running Lighthouse with the simulation conditions set to Moto G4 and a mobile data network. A score of 90 and above is considered good. The field dataset includes FCP, FID, LCP and CLS, displayed as coloured bars to indicate the percentage of good, normal and poor user experiences reported from opted-in real-world Chrome users. Measured at the 75th percentile, FID, LCP and CLS are used as the criteria in the Core Web Vitals report, which can be viewed in Google Search Console as an important SEO ranking factor for your website.
PSI provides an API for programmatic access to the report, which you can use to integrate with or build your own dashboards and tooling.
