Why teams pick Core Web Vitals Monitor

Core Web Vitals is a continuous discipline now, not a quarterly audit. Core Web Vitals Monitor unifies real-user data and lab tests so engineering can ship fast and stay fast.
RUM + lab in one view
Field data tells you what users feel, lab data tells you why. We unify both so engineers can debug a regression in one place.
Template-level breakdowns
Group performance by template, not just URL. Fix one React component, ship scores across thousands of pages.
Deploy-aware alerts
Webhook your CI pipeline and we alert you within an hour if a deploy regresses LCP, INP or CLS on any tracked template.

Frequently asked questions
How does this differ from PageSpeed Insights?
PSI gives a single-sample lab score. We give continuous RUM + lab segmented by template, country and device, with deploy correlation.
