Your website's performance, explained by an expert.
Metrical runs a real-browser performance test on your URL. AI translates the results into plain English and gives you a prioritized list of exactly what to fix first.
How it works
Three steps to faster pages
Real browser. Real conditions.
Enter any URL above. Metrical's performance lab runs your site across desktop and mobile profiles — measuring exactly what a real user experiences, not a synthetic estimate. Network throttling, multi-pass testing, and filmstrip capture included.

See your Core Web Vitals at a glance — LCP, CLS, INP, FCP, TTFB — with a frame-by-frame filmstrip of how your page loads. Then read the deep dive report: what each number actually means, what's causing it, and why it matters for your users and search rankings.
