What CMS Is This Site

What CMS is this site? See it in one click

A small Chrome extension that shows the CMS or site builder, the WordPress theme and plugins, the shop platform and the framework of the page you are on.

Add to Chrome

The extension window on a WordPress site: CMS WordPress 6.6.2, Confident; theme Astra Child and its parent Astra; plugins as chips; shop WooCommerce; framework jQuery; also found Google Tag Manager and Cloudflare.

What it shows

Open any website and click the icon. In about a second you see the engine behind the page: WordPress, Joomla, Drupal, Shopify, Wix, Webflow, Squarespace and many other CMS and site builders, with the version when the site shows it.

On WordPress sites you also get the theme, its parent theme and the plugins that load files on the page, by their readable names. Shops show their platform, and the card lists the JavaScript framework, CDN and tag manager it found.

Every answer has a label: Confident when the page shows clear signs, Likely when it shows fewer. When no known CMS is found, the extension says so and lists what it did see.

How it works

  2. Click the iconThe extension reads the page you are on, only after your click.
  3. Read the cardOr press Copy and paste the result into a note.

Private by design

The check runs inside your browser. The extension asks only for access to the tab you click on, keeps no history and sends nothing to us. Details are in the privacy policy.
