Watch speed and traffic in the same place.
Real-user LCP, INP, and CLS collected from the same script, shown next to your traffic. A slow page shows up before it quietly costs you visitors.

How it works
01
The browser measures the page
The script reads the Web Vitals the browser already computes for the real people loading your pages.
02
Field data, not a lab score
These are 75th-percentile values from actual visitors, the same signal search engines weigh, not a synthetic test.
03
Speed sits beside traffic
A regression on a high-traffic page is obvious, because the vitals are one click from the pages report.
Real users
Field measurements from actual visitors, not a lab run on one machine.
Three core
LCP, INP, and CLS, the metrics that decide the Core Web Vitals assessment.
In context
Shown next to the pages and traffic they affect, so a slow page is easy to catch.
