Enter a website to detect the platform and tools it runs on - from WordPress or Shopify to React, Google Analytics and the web server.

How can I find out what a website is built with?

This checker fetches the page and looks for tell-tale signatures in its HTML, scripts and headers to detect the CMS (such as WordPress or Shopify), JavaScript frameworks, analytics and tag tools, and the web server or hosting platform behind it.

How to detect a website's technology

  1. Enter the domain in the box above.
  2. Click Detect Technology.
  3. Review the detected CMS, frameworks, analytics and server.
  4. Detection is based on public signatures - a site can hide or customise them, so treat the result as a strong hint rather than a guarantee.
