Audit any site that runs RackCache.

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

Implied technologies

Detecting RackCache implies these are in the stack too - a report lists them alongside it.

How we audit RackCache

We measure the detected version against RackCache'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 Weak or outdated links weigh more - one risky dependency can pull the whole score down.
