How to tell if a website is built on Squarespace

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

Squarespace 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 Squarespace 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 “server”
  • Response header “x-contextid”
  • The page declares it in its “generator” meta tag
  • The page loads files from “static1.squarespace.com”
  • Page markup uses the class “sqs-block”
  • The site sets a cookie with a characteristic name
  • The domain’s DNS record points to “ext-cust.squarespace.com”
