It will always be the first question that comes in your mind that what CMS is this website using? while playing a role as a digital marketer, developers or an SEO specialist. When starting a new project or developing a website every person research for a platform that works best for their long term projects and this is the time when CMS detectors play an important role.

It doesn’t matter what’s the reason behind finding which website builder or CMS a website is developed on, there are several ways to perform this task, using the best CMS detector tools, that help to look into the source code from the browser. Let’s explore what a CMS is and what are the best CMS detector tools to find out which CMS a website is using.

What Is a CMS

A CMS, or Content Management System, is a software that is used to build, manage and modify a website and its content. It’s the best option for a less technical approach to website building, which doesn’t require you to write the code for the website.

A CMS is a content management system that consists of two parts:

  1. Content management application (CMA)
  2. Content delivery application (CDA)

Here I will further give you a brief about content management application and content delivery application.

Content Management Application

The content management application (CMA) is the part that manages and adds content on the website. It is the frontend interface where other users can manage the content easily.

Content Delivery Application

The content delivery application is the backend interface where the content is stored and uploaded to the website.

Some of the most popular CMS are:

  1. WordPress
  2. Joomla
  3. Magento
  4. Drupal
  5. Shopify
  6. Squarespace
  7. Wix

Detecting a CMS is the most important part of any website process; once you will find what CMS a website is using, you can easily perform vulnerability scanning.

What CMS is This Website Using

Detecting a CMS can be performed in many ways, which are slightly easier and also faster than others. It’s simple nowadays to detect some of the best CMS including WordPress, Joomla, and Shopify but there are several other platforms that can be difficult to detect while using the basic checking in the source code.

Before we go into in-depth research about some specific CMS detector tools, let’s take a look at some tricks to find out which CMS a website is using.

Quick Hacks to Find a CMS

There are some signs on a website that a website owner can’t remove, which will definitely tell you about the CMS that their website is using.

Some of the websites have a “Powered by” logo that is next to the name of the CMS in the footer.
There could be a favicon of the CMS in the browser tab. Mostly Joomla sites are having this favicon.

Since there are website owners that customize their websites and remove the above signs that I have discussed, you can also check their source code from the browser:

  1. You can use the option “Find on page” and type the name of the CMS.
  2. You can also see in the Head tag by searching <meta name=”generator” …> tag
  3. If the generator tag is removed then there is another option by typing some directories or tags that is specific for each CMS. However, you can check for a WordPress website using “wp-content” or just by typing WordPress, for drupal use “/sites/” or “/core/” and for Joomla searching “com_content” in the internal links.

Sometimes it is a time-consuming task and isn’t reliable because the developers remove those tags or customize the CMS that they use to build their websites. Also, there are some scenarios where the developers not using any CMS that takes a lot of time to search. This is where these best online CMS detector tools play an important role.
