Audit any site that runs Varnish.

Enter a URL to score its stack for technology quality, version health, Lighthouse performance - and AI-readiness.

How we audit Varnish

We measure the detected version against Varnish's release history and grade the surrounding stack with a Lighthouse-grade quality audit. Weak or outdated links weigh more - one risky dependency can pull the whole score down.
