What this checks
- WordPress, Shopify, Webflow, Ghost, Wix, Squarespace, and headless CMS clues
- Generator metadata, scripts, paths, framework signals, and hosting context
- Evidence-first results for sites that hide or strip obvious CMS fingerprints
How I treat the evidence
A CMS answer is most useful when you can see why it matched. WhosBuilt pairs raw detections with confidence and supporting infrastructure clues.
For headless or custom frontends, the CMS may be hidden. The report still shows the visible stack so you can decide whether the answer is unknown or merely indirect.
Does this detect headless CMS tools?
Sometimes. Public API paths, scripts, metadata, and page structure can expose them, but many headless sites leave no clear CMS fingerprint.
Can I use this for agency prospecting?
Yes. CMS plus host plus contact clues can show whether a site is likely self-managed, agency-built, or ready for a rebuild conversation.
