Real User Metrics
Paste or upload web-vitals samples or a CrUX export to see p75 with enough samples and a split by device, browser, region, viewport and route.
About this tool
Paste or open field data you already have: web-vitals samples as JSON or CSV, with one row per metric or per page view, or a response from the CrUX API or CrUX History API. Samples get a p75 for each Core Web Vital, shown only when there are at least 50 samples, and a split by device, browser, region, viewport and route.
A CrUX file carries its own p75 values, which are shown as they are. This page never collects metrics and never calls the CrUX API: it only reads what you give it, and rows that cannot be read are counted, not guessed. Files over 10 MB are refused and parsing stops after three seconds.
Interaction latency, release comparison and trend charts are features of the DevKit Forge browser extension.
