Core Web Vitals Visualizer
Open the popup on any page. See your LCP, CLS, INP, FCP, and TTFB scores instantly, color-coded, live. No separate tool. No copy-pasting URLs into PageSpeed Insights.
What it shows
Real-time scores powered by the web-vitals library, the same library Chrome uses internally. Green means good. Orange means work to do. Red means it's hurting you.
LCP - Green overlay marks the LCP element on the page. Full timing breakdown: TTFB, Resource Load Delay, Resource Load Duration, Element Render Delay. For images: preload status, fetchpriority, 1st vs 3rd party origin, natural vs rendered dimensions, estimated preload savings.
CLS - Pink overlays mark every layout shift source. Click any shift to see an animated before/after replay. Attribution shows the largest shift target and score.
