Run one desktop Lighthouse lab analysis through Google PageSpeed Insights. Review loading metrics, selected opportunities, and diagnostics.
Ways to go deeper with this site:
It requests a desktop PageSpeed Insights Lighthouse run for one URL and displays the Lighthouse performance score, lab LCP and CLS, Maximum Potential First Input Delay, FCP, Speed Index, Time to Interactive, Total Blocking Time, and selected audits.
No. The current integration reads Lighthouse lab audits and does not display Chrome UX Report field data. It cannot measure field INP, which requires real interactions. Use PageSpeed Insights, Search Console, CrUX, or your own real-user monitoring for field LCP, INP, and CLS.
Yes. The performance endpoint requires a signed-in account. Requests are limited to two per minute, and Google PageSpeed availability and quotas can also affect completion.
No. Each run analyzes the single submitted URL using the desktop strategy. Test representative templates and important journeys separately, then compare results under consistent conditions.
Lighthouse considers 90–100 good, 50–89 needs improvement, and 0–49 poor for that lab run. The score can vary with test conditions and does not certify real-user experience, search rankings, conversions, or the whole site.
No. Lighthouse estimates potential lab savings for selected audits. Confirm the affected resources and critical path, assess implementation risk, test the change, and compare repeated lab runs plus field data.

This tool requests one desktop Lighthouse performance run through Google PageSpeed Insights. It displays the lab performance score, LCP, CLS, Maximum Potential First Input Delay, FCP, Speed Index, Time to Interactive, Total Blocking Time, and selected Lighthouse opportunities and diagnostics. It does not crawl the site or display field INP or CrUX data.
A Lighthouse run is useful for reproducing a page load in a controlled environment and opening diagnostics. Field data describes eligible real visits across devices, networks, geographies, cache states, and interactions. Compare both sources: investigate important field problems with traces, and verify lab improvements against real-user experience and the business outcomes that matter to the page.
Lighthouse opportunities estimate potential savings for that synthetic run. Open the underlying audit, confirm which resources and work are involved, and assess dependencies before implementation. Repeat the test under comparable conditions, check visual and functional behavior, and watch field metrics after release. The displayed estimates are diagnostic inputs, not guaranteed gains or fixed implementation scopes.
