What CMS is used by a website? Yours or someone else’s

How to detect the CMS of that cool website

CMS or a website engine is a program framework a website is written on. Administrators hardly ever write their own engines, they tend to use the popular ones: WordPress, Drupal or Joomla.

You don’t know what CMS is used by your website, or you want to detect the CMS of that cool website? Try one of the methods below:

Method 1. Look for the CMS name in source code

The easiest way to detect CMS is to look for references in the website’s code. You can often come across a CMS name in plugins, internal links or meta tags:

  • Open a website and press Ctrl + Shift + I. The source code will open.
  • Now press Ctrl + F and search CMS by name one by one: WordPress, Joomla, Drupal, Bitrix, etc.

On the first try! Yes, this one is on WordPress, the most popular CMSOn the first try! Yes, this one is on WordPress, the most popular CMS

Method 2. Detect CMS through Robots.txt

Robots.txt is a special file for search engines. In there, administrators specify what Google bots can and cannot index. Most CMSs generate this file on their own and leave a reference to themselves.

  • Follow the link: Website_address /robots.txt
  • Press Ctrl + F and search the file for popular CMS names: WordPress, Joomla, Drupal, Bitrix, etc.

Method 3. Try to enter the admin panel

Almost all website configuration processes take place in the admin panel. Many administrators leave a standard login page. Don’t do this on your website — you’ll only make it easier for hackers to crack your password.

We won’t tell you the details of the cracking process but we’ll leave standard login links to the admin panel. Try to follow them in order to detect CMS of your website:

Page CMS
Website_address/wp-login.php or Website_address/wp-admin WordPress
Website_address/administrator Joomla
Website_address/admin Drupal
Website_address/manager Modx
Website_address/bitrix/admin/ Bitrix

Method 4. Use special services
