CMS Detector

Instantly identify the CMS, frameworks, server, CDN and plugins used by any website from its URL — JSON and CSV export. No sign-up required.

What is CMS Detector for?

CMS Detector inspects any URL and reveals the technologies running the site: the content management system, but also the frameworks, the server, the CDN, the analytics tools and, when they are exposed, the plugins and themes. Every finding comes with a confidence level and the evidence behind it, so you can check it yourself.

CMS identification

WordPress, Shopify, Wix, Drupal, Joomla, Webflow and many more, with the version when it is exposed.

Technologies and server

Frameworks, language, web server, CDN and analytics services detected in the code and headers.

Evidence-backed

Each detection cites the clue that triggered it and a confidence level, with no black box.

How it works

  1. Paste the URL of the site to analyse.
  2. Run the detection: the tool fetches the page and examines its code, headers and resources.
  3. Browse the technologies found, their evidence and confidence level, then export if needed.

Frequently asked questions

How does CMS Detector identify a CMS?

It analyses the HTML, HTTP headers, scripts, file paths and known fingerprints to infer the CMS, with a confidence level and the supporting evidence.

What is detected besides the CMS?

Front-end and back-end frameworks, web server, language, CDN, analytics, fonts, and plugins or themes when the CMS exposes them.

Can I export the results?

Yes, every analysis exports to JSON or CSV so you can archive or process it elsewhere.
