PageSpeed Insights
Site HealthTestedCore Web Vitals, Lighthouse scores, performance audits, and optimization recommendations.
PageSpeed Insights runs Google Lighthouse audits on any URL, measuring Core Web Vitals (LCP, CLS, INP), performance scores, accessibility compliance, SEO best practices, and more. Agentcy strips the massive raw audit data down to the metrics that matter.
Ask about your site speed, Core Web Vitals scores, or mobile vs desktop performance. Agentcy handles both lab data (simulated Lighthouse runs) and field data (real Chrome UX Report metrics) when available, giving you a complete performance picture.
This is a zero-config service — no API key or domain setup required. Just enable it in your portal and start scanning any URL.

The first scan for a URL runs a fresh Lighthouse audit, which takes a few seconds longer than cached results
Mobile and desktop results can differ significantly — specify which you want, or Agentcy scans both
Lab data (simulated) and field data (real users) often show different numbers — both are useful
Very slow pages may time out during the Lighthouse audit
