About Web Vitals Explorer

Web Vitals Explorer is a free tool that shows Core Web Vitals — LCP, INP, CLS, FCP, TTFB — for any domain on the public web. The data comes straight from Google's Chrome UX Report (CrUX), which aggregates real user measurements from the last 28 days of Chrome traffic.

Field data like this is what Google actually uses for its page-experience signal. Lab tools like Lighthouse are great for debugging, but a page that's fast on your laptop can be slow for real users on flaky mobile networks. CrUX closes that gap.

Why we made it

Every time you want to check a site's vitals, you're clicking through PageSpeed Insights or a paid SaaS dashboard. This site gives you the same numbers in one click, and it's free because we make nothing off you directly — the site is funded by on-page display ads.

How we make money

Display advertising only. No paid tier, no email capture, no affiliate links. See the privacy policyfor what we do and don't collect.

Coverage

CrUX has data for any origin with enough Chrome traffic to anonymize (roughly: more than a few hundred weekly users). Very small or very-new sites will not have data. That's expected.
