About CrUX Vis
CrUX Vis is a tool from the Chrome team for exploring Chrome User Experience Report data. You enter a web page or origin and it draws charts of real-user measurements collected from Chrome, including Core Web Vitals, along with links to articles that explain the metrics.
Because the data comes from real visitors, it shows how a site performs in practice rather than in a lab test. It suits developers tracking performance trends for sites with enough traffic to appear in the report.
Strengths
- Uses real-user field data from Chrome
- Charts trends for a page or a whole origin
- Links to explanations of each metric
Limitations
- Only covers sites with enough Chrome traffic to be in the report
- Shows measurements but does not run tests itself
