Real headless Chrome Mobile + Desktop Core Web Vitals Audit history Free, no signup

Free Online Lighthouse Audit Tool

Run a real Google Lighthouse audit on any public URL with one click. Our tool spins up a headless Chrome instance and runs the official Lighthouse engine against your page, returning the same scores you'd get from Chrome DevTools or PageSpeed Insights: Performance, Accessibility, Best Practices, and SEO. You also get every Core Web Vital that Google uses as a ranking signal โ€” Largest Contentful Paint (LCP), First Contentful Paint (FCP), Cumulative Layout Shift (CLS), Total Blocking Time (TBT), Time to First Byte (TTFB), Speed Index, and Time to Interactive (TTI). Choose between mobile and desktop strategies, and pick which categories to test. Every audit is saved so you can compare runs over time. Free, no signup, no API keys.

Also try our SEO Checker

Lighthouse measures page performance and Core Web Vitals. For a full technical SEO audit โ€” crawl your entire site for 79+ issues including broken links, missing meta tags, duplicate content, security headers, and more โ€” use our AI SEO Checker. It scores your site 0โ€“100, groups issues by severity, and generates copy-paste-ready fixes with AI.
