Website Speed Test

Check real website speed metrics using live Lighthouse data

Live

Enter any public URL to analyze performance, Core Web Vitals, and loading behavior. Results include mobile or desktop scores plus actionable metrics like LCP, FCP, TBT, and CLS.

Tip: run tests for both mobile and desktop, then improve high-impact issues first (large images, render-blocking scripts, and slow server response).
