How to tell if a website is built on HubSpot CMS

Paste any domain and we will tell you whether it is HubSpot CMS, how sure we are and which signs gave it away.

HubSpot CMS is a content management system.

Free, no sign-up. We make up to four requests, like a visitor: the home page, robots.txt and the sitemap — and read public signs only.

Signs of HubSpot CMS we look for

None of these alone is proof on every site; together they give a confidence level. You can also check most of them yourself by viewing the page source and response headers.

  • Response header “x-hs-hub-id”
  • Response header “x-hs-portal-id”
  • The page declares it in its “generator” meta tag
  • The page loads files from “/hubfs/”
  • The page loads files from “hs-sites.com”
  • The domain’s DNS record points to “hscoscdn”
