10 Most Popular Headless CMS of 2021

Welcome to the 10 Most Popular Headless CMS of 2021! Never before has managing your website’s content been more important. Therefore, now more than ever, businesses need to be as aware as possible of which online systems are functioning best and which are simply inadequate. And we mean that from both technical point of view as well as non-technical.


Traditional CMSs, as we’ve seen from past articles, are great from a non-technical point of view. However, there are certain limitations as to what technology can be used on them, which also has a massive impact on how much design and functionality customization one can do when building a new platform.


As a response, the technology community created the headless CMS. So today, we will do a quick recap on what a headless CMS is and then dive into the most popular headless CMS of next year.


Let’s begin!


What is a Headless CMS?

If you are not exactly sure what we are referring to with the term “Headless CMS”, think of your normal CMS, but without the interface, or head.


Traditional Content Management systems, like WordPress for example, come with a theme or a predefined frontend which dictates how the user interface looks like and how the user interacts with it. Headless CMSs don’t have that. They instead allow developers to create their own layout and UI and, most importantly, choose their own technology to do so.


What this means is that these systems do not display inputted content on a front-facing website, instead, they include:

  • An API (Application Programming Interface): A collection of functions that allow applications to access data and interact with external software components or operating systems
  • A backend system: An isolated system that contains a database and the functionality for the future website.


The main objective when using a Headless CMS is to publish content to a web service via the application programming interface, which will allow any type of website content to be delivered and viewed no matter what the device being used (e.g., smartphone, tablet, laptop).


Furthermore, no hosts are necessary. Due to this, the maintenance of a headless CMS is far more straightforward than maintaining a non-headless CMS.



As is obvious, just a few benefits of using headless CMS are their compatibility, flexibility, and security.


Now, let’s dive into the best and most popular Headless CMSs of 2021!
