PageSpeed & Core Web Vitals

Measure your site the same way Google does.

Codicer runs live Google Lighthouse reports (performance, accessibility, best practices, SEO scores) on any URL — plus real-user metrics from the Chrome UX Report (LCP, INP, CLS, FCP, TTFB). Know exactly what Google sees when it ranks your pages.

What it does

  • Performance score (0–100) from Lighthouse
  • Accessibility score
  • Best practices score
  • SEO score
  • Largest Contentful Paint (LCP) — loading
  • Interaction to Next Paint (INP) — responsiveness
  • Cumulative Layout Shift (CLS) — visual stability
  • First Contentful Paint (FCP) and TTFB
  • Real-user field data from Chrome UX Report
  • Mobile and desktop strategies

How to use it
