Webmatik vs Google Lighthouse

Google Lighthouse is a free, open-source tool that audits a single page for performance, accessibility, best practices, SEO, and PWA.

Open-source page-quality auditor

Where Google Lighthouse shines

  • Free, open-source, and built into Chrome DevTools
  • Authoritative Core Web Vitals and Lighthouse performance score
  • Great for engineers debugging a single page in the browser

Where Webmatik is different

  • Scores 8 categories — including conversion, retention, security, and GEO (AI search visibility) — not just performance/SEO/a11y
  • AI vision analysis of the actual rendered design, not just the DOM
  • Audits your homepage plus key inner pages in one run, not one page at a time
  • Returns a prioritized, plain-English action plan instead of raw metrics
