About WhatCMS

WhatCMS checks a page for thousands of artifacts to work out whether it was generated by a content management system and which one. It currently detects around 1,540 website technologies, including e-commerce platforms, web frameworks, programming languages, hosting and CDNs.

Beyond single lookups, the site offers batch detection, an API with documentation and technology reports for building lists of companies by tech profile, hosting provider, theme, language and domain. It suits developers, agencies and sales teams researching sites.

Strengths

  • Detects about 1,540 website technologies
  • Reports framework, language, hosting and CDN alongside the CMS
  • Batch detection and documented API

Limitations

  • Detection relies on visible artifacts and can miss customised sites
  • Lead generation features go beyond simple site checks
