How to tell if a website is built on Duda

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

Duda 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 Duda 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 “d-cache”
  • Response header “d-on-d”
  • The page loads files from “cdn-website.com”
  • Page markup uses the class “dmRespRow”
  • The domain’s DNS record points to “multiscreensite.com”
