View the source code of a website

Go to the website whose source you want to view and click the right mouse button.

  • With Internet Explorer, you choose ‘View source’ or ‘Show source’ depending on the language settings
  • With Firefox or Chrome, select ‘View page source’ or ‘View page source’ depending on the language settings.

Discover the Content Management System used

What you now see in front of you is the source code of the website. You can search for specific terms used in the source code or enter a term using the search function (CTRL + F). Each CMS uses a specific folder structure by which you can recognize them.


Search for ‘/ templates /’ like:

<link rel = "stylesheet" href = "/ templates / system / css / system.css" type = "text / css" />


Search for ‘/ sites /’ like:

<img src = "sites / all / modules / drupalorg / drupalorg / images / d8.svg" alt = "Drupal 8">


Search for ‘/ wp-includes /’ like:

<link href = "// sworg / wp-includes / css / dashicons.css? 20141219" rel = "stylesheet" type = "text / css" />


Search for ‘/ skin / frontend /’ like

<link rel = "shortcut icon" href = "" type = "image / x-icon" />


Search for ‘/ typo3conf /’ like:

<img src = "/ typo3conf / ext / t3org_template / i / typo3-logo.png" width = "118" height = "34" alt = "TYPO3" title = "TYPO3" />


Search for ‘/ Portals /’ such as:

<link href = "/ Portals / _default / default.css? cdv = 354" media = "all" type = "text / css" rel = "stylesheet" />

As you can see, it is quite simple to discover which CMS a website uses.

Are you researching which CMS you want to use?

Then keep in mind that a CMS is responsible for managing and displaying the content. An important consideration here is open source vs. closed source.

Have you made this choice? Don’t look at factors such as the design and findability of a website. These are not determined by the CMS.

A web design consists of CSS and HTML and can be applied to any CMS. Findability is largely determined by the content that you place in the CMS.

If you’ve ever been curious about the technical aspects of a website, wondered how it functions, or how it’s built, you’re in the right place. In this beginner’s guide, we’re diving into an essential question – how can you see which Content Management System (CMS) a website is using?

CMS is the behind-the-scenes powerhouse that allows website owners to manage their content efficiently. But, how can you find out which CMS a website is using? Fortunately, the answer isn’t as complicated as you might think.

What is a CMS?

Before we get into the nitty-gritty, let’s take a moment to understand what a CMS is. In simple terms, a Content Management System is a software that facilitates creating, managing, and modifying digital content on a website without needing specialized technical knowledge.

Think of the CMS as the backbone of any website, giving non-technical users the power to manage their content with ease. Popular CMS platforms include WordPress, Joomla, Drupal, and Squarespace, among others.

Why Would You Want to Know a Website’s CMS?

Now, why would anyone want to know what CMS a website is using? Here’s why:

  1. Competitor Analysis: Knowing what CMS your competitors are using can give you insights into their website’s functionality, which you might want to incorporate into your own site.
  2. Web Development: If you’re a web developer or a digital agency, understanding a website’s CMS can help in designing a similar or improved platform for your clients.
  3. Security Research: If you’re into cybersecurity, understanding the CMS can help you identify potential vulnerabilities in a site, allowing for improved security measures.

Identifying a CMS: Manual Methods

If you’re a keen observer, there are a few manual ways to guess which CMS a site uses.

View Page Source

Right-click on a webpage and select “View Page Source” or “Inspect”. This action opens the raw HTML code of the site. Once there, look for lines mentioning the CMS like ‘wp-content’ (for WordPress) or ‘sites/all’ (for Drupal). It’s a bit of detective work, but it’s a start!

URL Structure

The structure of a website’s URL can give hints about its CMS. For example, URLs containing ‘wp-content’ or ‘wp-includes’ indicate WordPress.

Website Footer

Some websites mention their CMS in the footer. Phrases like “Powered by WordPress” or “Built with Joomla” are dead giveaways.

While manual methods can work, they’re not foolproof. Therefore, we turn to automated tools.

Automated tools take the guesswork out of identifying a website’s CMS. They provide accurate results with just a few clicks. Here are some of the top tools you can use:
