PageSpeed Insights
Google's free tool that uses Lighthouse for lab data and CrUX for field data to report on a URL's Core Web Vitals and performance.
PageSpeed Insights (PSI) is Google's public-facing interface for performance assessment. It combines Lighthouse lab scores with 28-day CrUX field data for the same URL. PSI scores are widely used but are manual — AuditJet automates PSI-equivalent monitoring on a schedule with alerting and revenue impact.
