Headless CMS Explained - Guide to Content Management Systems

Headless CMS Explained

Headless and Decoupled content management systems (CMS) have become standard for modern web teams. Composable architecture has proven its advantage over traditional CMS for teams of all sizes, especially enterprises. It's easier to manage content across digital teams, making it more collaborative for content editors and content creators.

Learn about Headless CMS

We can’t say that headless content management systems, and composable for that matter, are all the rage now in web development but they are pretty close to becoming mainstream tech. A serious contender to LAMP and MEAN stacks dominance if you will.

When we talk about static websites, the first thing that comes to mind is a bunch of web pages coded using HTML, CSS, and JS. Just plain text and graphics-based interface with no interactive features and real-time processing whatsoever to facilitate the visitors.

Fortunately, that’s not the case for static websites of today.

Static websites have evolved to embrace innovative technologies and today they can do things such as handling real-time requests, processing payments, managing customer accounts, carrying out full website searches, and a lot more. That’s why we don’t call them static anymore, we now call them composable websites.

OK. This might be an overstatement considering the discussions and debates we currently have about the terms we use on a day-to-day basis.

From Jamstack to Composable

While Jamstack revolutionized web development by decoupling the front-end from traditional backend servers, the concept of composable architecture takes it a step further.

Jamstack, as you know, eliminates the need to manage specific web technologies, freeing developers to focus on the core functionalities of their website or app. This approach offers the benefits of static websites while enabling dynamic content.

However, composable architecture expands this modularity beyond the front-end. It allows for independent, interchangeable components across the entire tech stack – from headless CMS and databases to functions and APIs. This composable approach fosters greater flexibility, scalability, and future-proofing for your project.

In essence, Jamstack laid the groundwork for a more composable web, and its principles of pre-rendered content and APIs are key building blocks in this evolving architecture.

What is headless CMS?

Headless CMS is a content management system that separates back-end content management functionalities from the front-end presentation layer.

Simple right?

Headless CMS vs. traditional CMS

Traditional CMSs like Drupal and WordPress are hosted and served with the website every time a request for a page is made. This basically means that the traditional CMSs are built with back-end and front-end bundled into a single application that is web-first.

A diagram illustrates the workflow of a traditional CMS system, showing how content moves through back-end UI, code and plugins, to front-end templates and CSS across web server and database components.

How "traditional" CMS works

Headless CMS, as we already pointed out, decouples content management from the presentation layer. This means that your content management functionalities (like creation, management, and how digital content is stored) are separate from your front end allowing you to deliver content beyond websites and apps. It allows you to repurpose your content from multiple front-ends making them a perfect fit for composable builds.

Headless CMS vs. decoupled CMS

Before we dive deeper into headless CMS, let's clear up a common question: Are headless CMS and decoupled CMS the same thing? Let's quickly differentiate between the two.

The difference between a headless CMS and a decoupled CMS lies primarily in their approach to separating content from code and their relationship with the presentation layer.

A headless CMS completely separates content from the code and does not include a default frontend presentation layer. This means developers have full control over how they display content. Content from a headless CMS can be utilized anywhere it's needed without any pre-defined presentation format.

On the other hand, a decoupled CMS also separates content from code, but it does include a presentation layer, or "head," which is optional to use. While still providing flexibility by separating content from code, a decoupled CMS remains linked to a specific presentation format, commonly a website. This means it sacrifices some of the flexibility of a headless CMS but offers a middle ground between a traditional monolithic CMS and a headless one.

What are the benefits of headless CMS?

With so many brands focusing on repurposing their content on multiple front ends, the growing demand, and the number of headless CMS solutions, should not come as a surprise. Especially when you look at all the benefits a headless CMS offers:

  • Hosting is delivered as Software as a Service (SaaS). And since there is nothing to maintain, security is also delivered as SaaS.
  • Most headless CMSs have an SLA (service-level agreement) in place which gives you peace of mind in terms of uptime for example.
  • Content exists as a separate component altogether and is used when needed through an API request, enhancing the efficiency of content delivery.
  • Headless CMS gives you complete control over how your content will appear and presented. No forced reliance on themes and templates.
  • You can reuse and repurpose the same content over and over again.
  • It doesn’t matter what programming language or framework you are using, headless CMS integrates with any codebase.

When to use headless CMS?

It is hard turning a blind eye to the benefits of using a headless CMS from both web developers’ and marketers’ perspectives. Faster performance, more security, and easier scalability being the top among many.

On top of that people are making use of more devices and channels than ever before. In a climate such as this, businesses/brands are forced to make omnichannel strategies to be able to get to their potential customers wherever they may be.

With that in mind, we should ask something else.

Do I need headless CMS?

Honestly, no one but you can answer that question. Right now headless CMSs are considered future-proof mainly because of a clear distinction between the content and presentation.

However, only understanding your short-term and long-term business and content goals can help you choose which content management model will best serve your business.
