TL;DR [too long; didn't read] 🤯
  • Headless CMSs easily allow content to be shared across platforms.
  • Headless CMSs do not care about the front-end.
  • Traditional CMSs can be difficult to scale effectively.
  • Traditional CMSs generally have preferred programming languages.
  • Headless CMSs allow you to use any programming language.
  • Contensis is a really great CMS, which you should totally check out.

The first content management systems (CMS) were developed in the late '90s when webmasters needed a way to manage the content of their growing websites. As technology has developed over the last three decades CMSs have not only become more sophisticated, but also more specialised. Today, if you search for the term 'CMS' you'll be overwhelmed with hundreds of options – which can be a little confusing, to say the least.

It's likely that any CMS you've used up to this point was a traditional CMS like Wordpress, Joomla or Drupal. Until recently these kinds of CMS dominated the market. Now that more people are looking to publish their content on other platforms besides websites, the popularity and demand for headless systems has grown – which is why it's important to learn the differences between a headless CMS such as Contensis, and an older-style traditional CMS.

What is a traditional CMS? 🤔

In a traditional CMS, the back-end (the database and the admin area where you manage the content) and front-end (where your content is displayed) are directly connected to each other. A traditional CMS will usually allow editors to make changes to the visual side of the website without requiring much, if any, developer experience. This ease of use has made traditional CMSs hugely successful, but it also creates limitations as to what you can achieve with a traditional monolithic CMS.

One of the main limitations of a traditional CMS is how the content gets delivered. Because the content and design are so closely coupled, you can generally only deliver your content to a website. If you want to share your content across different devices or platforms, you will have to use a different system – which could become difficult to scale and would be time-consuming to maintain.

Traditional CMSs usually have a preferred programming language too. This means that if you choose a content management system that has a template language of PHP, you will have to use PHP to serve your content, which doesn’t give you much flexibility.

What is a headless CMS? 🤔

A headless content management system (CMS) is a content repository which enables content to be accessible via an API to any device.

So, you wouldn't be mistaken in thinking a headless CMS is pretty much just a place to store content in a way that is easily accessible. The power of a headless system comes from the fact that it's language agnostic – it allows developers to serve content using any programming language. This means you can choose the most suitable language to deliver content to any platform – from websites and mobile apps to wearables and business systems.

While your content is stored in the CMS, the code that runs your website or app is stored separately, usually in a distributed repository. This means that it's much easier for teams working remotely to work on code at the same time without causing conflicts – something that’s proving essential in the current ‘working from home’ landscape we’re recently finding ourselves in due to COVID.

Because a headless CMS keeps your content separate from your code base it also allows you to be agile and use continuous delivery practices such as version control and automated testing to release features faster and more safely while seeing an earlier return on investment.

Wondering where the word 'headless' comes from? It's simply the concept of chopping the 'head' which is the front-end off the 'body' which is the back-end – the content repository.

When you think of 'headless' you think you are getting less. But in this case especially, 'less' is definitely more.

What are the main differences between a headless CMS and a traditional CMS? 🔍


  • One place for all your content – manage all of your content for all of your systems using the same interface, meaning you can deliver content faster with fewer mistakes.
  • The 'back-end' of the CMS is run independently from the ‘front-end’ where content is displayed.
  • Build omnichannel experiences – easily distribute content across different platforms from a single back-end.
  • Scalable, easy to customise, and very flexible.
  • Requires developers or developer support.
  • The front-end can be language agnostic – a headless CMS allows a developer to use any language or framework they are comfortable using, whereas a traditional CMS typically requires the use of a specific framework and language.


  • Content is edited using a 'What You See Is What You Get' (WYSIWYG) interface because they only have one context for presenting the content which is typically a web page.
  • The 'back-end' is intrinsically connected to the 'front-end'.
  • Often restricted by programming language.
  • Web pages can be created without much developer input.
  • Limitations on where and how content can be delivered.
