Frequently asked questions
How does the CMS checker work?
It scans HTML structure, meta tags, headers, file paths and script signatures, then matches them against a database of CMS fingerprints.
Can it detect a CMS that's been customised?
Usually yes – most CMSs leave structural signatures even when heavily themed, though very custom builds can be harder to fingerprint.
Is the CMS checker free?
Yes, single-site checks are free with no signup.
