How to tell if a website is built on WordPress

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

WordPress 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 WordPress 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 “link”
  • Response header “x-powered-by”
  • Response header “x-pingback”
  • The page declares it in its “generator” meta tag
  • The page loads files from “/wp-content/”
  • The page loads files from “/wp-json/”
