About PageSpeed Insights
PageSpeed Insights analyzes a URL and reports how fast it is on mobile and desktop. It combines field data from real Chrome users with a Lighthouse lab test, so you see both how visitors experience the page and a reproducible audit with suggestions.
It needs no account or setup: paste a URL and run the analysis. Documentation and release notes are published on Google's developer site, and the tool is a common first stop when checking Core Web Vitals.
Strengths
- Field and lab data side by side
- Separate mobile and desktop results
- Lighthouse suggestions for improvements
- No account needed
Limitations
- Field data only appears for URLs with enough Chrome traffic
- Single-page checks rather than ongoing monitoring
