Common questions

Every HubSpot CMS Hub theme serves its static assets from a /hubfs/raw_assets/public/<theme-name>/ path. We scan the page's HTML, inline styles, and linked stylesheets for that path and extract the theme folder name.
Yes. As long as the site is built on HubSpot CMS Hub and serves assets through its hubfs CDN paths, detection works whether it's on a default hs-sites.com subdomain or a connected custom domain.
Some themes only reference their asset folder from an external stylesheet (e.g. a background-image rule). We fetch linked CSS files and check those too before giving up.
Yes. HubSpot Detector only reads publicly available information — the same asset URLs any browser loads when visiting the site. We never attempt to access the HubSpot portal or exploit any vulnerabilities.
