Audit any site that runs Backdrop.
Enter a URL to score its stack for technology quality, version health, Lighthouse performance - and AI-readiness.
Implied technologies
Detecting Backdrop implies these are in the stack too - a report lists them alongside it.
How we audit Backdrop
We measure the detected version against Backdrop'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 Weak or outdated links weigh more - one risky dependency can pull the whole score down.
