All monitors

Speed & Core Web Vitals monitoring.

Fast pages rank and convert — slow ones bleed both. These monitors track your Core Web Vitals two ways: a controlled real-browser lab run, and field data from your actual visitors (p75), so a regression shows up before your ranking does.

Lab vs real users

Website speed monitoring that shows what visitors actually get

Most website speed monitoring stops at a lab score. Relvato runs both monitors in this category — a lab run in a real browser and your visitors' own timings — and draws them on one radar chart per device: LCP, INP, CLS, FCP and TTFB, real users filled, the lab dashed on top. You'll find it in the app's Performance tab and in the WordPress plugin's dashboard.

What matters is where the shapes part. Here every page loads fast in both, yet real taps and clicks take 290 ms to respond, while the lab's Total Blocking Time stays at a good 140 ms. That's Interaction to Next Paint, a metric a lab run can only approximate — so lab-only monitoring would call this site fast. The circled axis tells you which monitor to open and which number to fix. Core Web Vitals vs RUM explains why the two disagree.

One gap, circled: pages load fast for everyone, but real visitors' clicks respond in 290 ms — the INP a lab run can only approximate.
