Core Web Vitals monitoring for the pages that make money.
Produl turns real visitor Web Vitals into clear p75 scores, route-level diagnostics, deploy context, and alert-ready trends. See when LCP, INP, CLS, FCP, or TTFB slips before search traffic and conversions feel it.
The performance signals your users actually experience.
Lab tests are useful before launch. Field data tells you what happened on real devices, networks, browsers, and routes after launch.
Real visitor samples
Measurements are captured from actual sessions, then rolled into p75 values that match how performance is judged in practice.
Page and device breakdowns
Rank routes by the metric that hurts most, then filter by mobile, desktop, country, referrer, and time range.
Regression-ready context
Pair Web Vitals with deploy annotations, alerts, and traffic changes so a bad release is easy to spot and roll back.
Open a metric, find the bad route, fix the source.
Each card below behaves like the production workflow: scan status, expand for the likely cause, then drill into page-level bars. No dashboard archaeology required.
Largest Contentful Paint2.1sGood
Find slow hero images, server delays, render-blocking scripts, and route-level regressions before they become search and conversion problems.
Good at 2.5s or faster
Interaction to Next Paint148msGood
Track responsiveness from real clicks, taps, and keyboard interactions so heavy client-side work is visible the same day it ships.
Good at 200ms or faster
Cumulative Layout Shift0.06Good
Catch unstable ads, late-loading embeds, and unreserved media space with page-level visual stability measurements.
Good at 0.10 or lower
First Contentful Paint1.4sGood
Understand when users first see content and separate server, network, and frontend rendering issues from the rest of your funnel.
Good at 1.8s or faster
Time to First Byte640msGood
Monitor backend response time from the browser perspective, broken down by route, country, and device class.
Good at 800ms or faster
Prioritize the pages with the most performance debt.
Detect the regression
Watch p75 values move over time and separate a real user slowdown from one noisy outlier.
Segment the blast radius
Check whether the issue is mobile-only, route-specific, regional, or tied to one referrer.
Verify the recovery
Ship the fix, annotate the deploy, and confirm that the same metric returns to green.
