How to tell if a website is built on Webflow

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

Webflow is a website builder.

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 Webflow 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-wf-region”
  • Response header “x-wf-page-id”
  • The page declares it in its “generator” meta tag
  • Page markup has the attribute “data-wf-site”
  • The page loads files from “website-files.com”
  • The domain’s DNS record points to “webflow.com”
