Headless and Decoupled Architecture: What’s the Difference?

Headless CMS and Decoupled Architecture in 2023

Headless CMS vs Decoupled CMS

Let’s discuss today what does headless architecture mean and actual difference between headless architecture and decoupled architecture. We’ve been hearing a lot more about decoupling architecture than headless architecture. We don’t know whether it’s just that monoliths right now have seen the way in terms of headless frontend architecture and are forcing themselves into that space. 

But the only way to differentiate between the two of them is to understand what headless architecture vs microservices.

When we’re consulting with the clients and business people out there, the thing is, They hear someone say, “Well, and it’s not headless.”

Their eyes glaze over with headless infrastructure that’s decoupled architecture, in simple, they’re the architecture without architects.

Headless and Decoupled Architecture: What’s the Difference?

What is a Headless CMS Architecture?

And they have no idea what you’re talking about, why they care, and what difference it makes. So we’re going to take you through what is a headless CMS architecture quickly and give you an understanding of what people mean when they talk about headless API architecture and decouple architecture.

So let’s waste no more time; let’s get to it. First of all, we will start with the traditional monolithic web CMS. For simplicity, we will help you represent different content types here. 

What is decoupled architecture and how it differs from headless architecture?

Despite the apparent flexibility provided by headless CMS, marketers have embraced decoupled architecture because it addresses the problems brought on by the lack of presentation control. When choosing a CMS with a decoupled architecture, many businesses look for advantages such as maintaining control.

Naturally, the back end and front end of a decoupled system are, well, decoupled. A decoupled architecture uses front-end code, templates, WYSIWYG controls, and more to modify the presentation. Furthermore, it makes use of web services, templates, and APIs to deliver that content to any presentation channel, anywhere.

That is unquestionably a quicker and more reliable solution than traditional CMS. and can provide users who prefer to have some presentation control in addition to flexible delivery with the best of both worlds.

Decoupled architecture speeds up design iterations and lessens dependencies between publishers and developers. Additionally, it supports third-party integrations, streamlines deployment, increases security, and is resistant to headless UI architecture changes in the future.

From a developer’s point of view, they may prefer the total freedom that comes with an API-only approach and don’t need the flexibility that is enjoyed with decoupling, which is why a user wouldn’t adopt it.

What is the main difference between Headless and Decoupled Architecture?

With all the CMS architecture patterns built-in at this time, they were very opinionated. They were built for a specific purpose, like a web marketing channel. They defined a particular ecommerce technology stack, the delivery model such as pages and components, and even the infrastructure. 

The database that would sit at the core of these systems was usually SQL. It is where you save what types of content you could use, what components you could use, how the pages were structured, templates, and navigation being opinionated about front-end technology. So, now got a loose idea about what headless software architecture means, right?

However, the database meant they could represent content and UI elements directly out of the database in an excellent, user-friendly headless UI. So the business users would use the content types and components available to assemble the needed pages. 

These pages would be stored in the database and reassembled in the business logic layer templates to turn the page objects into actual pages that were fully styled and ready for the head or the presentation layer, as these systems had a very tight binding between templates and business UI.

Pros of traditional CMS, decoupled CMS & headless CMS

Traditional CMS:

  • Has a pre-built, user-friendly interface for managing and organizing content
  • Often includes built-in templates and design elements, making it easy to create a visually appealing website without needing web development expertise
  • Can be a good option for small to medium-sized websites that don’t require a lot of custom functionality

Decoupled CMS:

  • Allows for greater flexibility in the front-end design and development of the website
  • Can be a good option for large, complex websites that require a lot of custom functionality
  • Allows for easy integration with other tools and services, such as e-commerce platforms and marketing automation software

Headless CMS:

  • Allows for even greater flexibility in the front-end design and development of the website
  • Can be a good option for websites that need to be delivered to multiple channels, such as web, mobile apps, and voice assistants
  • Provides a more efficient workflow for development teams as they can work independently and not block each other
  • Allows for more scalability and ease of integration with other systems

When to go with Headless CMS Architecture over Decoupled Architecture?

Being opinionated and closely coupled across all the layers often means that these CMS will have WYSIWYG editing intervention. The challenge comes when you want to manage more than one single channel. Some of these channels require more complicated content or content types that don’t exist in traditional CMS. 

This is where headless CMS steps into the fascinating and powerful thing about headless integration. Unlike traditional CMS, you’re given predefined components, content types, pages, and templates to assemble your customer experience. 

Headless Architecture Benefits over decoupled one

The headless API architecture allows business users to model their business concepts from within their business domain into the headless architecture pattern for. Business users can use these custom content types to create the exact content they need, allowing them to provide much better customer experiences in each channel. So with the benefits of headless CMS, you don’t get predefined content types defined inside a database table. You can create your own content types using schemas.

So we’ve defined a traditional monolithic web CMS and a headless CMS, so what is the architecture of a decoupled CMS? When a conventional CMS wants to go, what is a headless website, this usually starts by replacing the templating layer with a headless API. These headless APIs will wrap all the objects and calls in the business logic layer and the predefined content types and objects in the database layer. 

So everything stays the same; you have an API version of a template. In other words, you’ve decoupled your head from the base CMS. When you try to use it with other channels, you can only use the predefined content types in the CMS. 

In this case, it’s like trying to use a square peg in a round hull. Also, if you need to generate more complicated content types, you have to try and build them from the ones you already have in the CMS. 

So, putting an API on a traditional monolith does decouple the monolith from the head. But it doesn’t make it purely a headless application architecture to do so. You must fundamentally change the architecture and the implementation through every single layer.


So we hope you run through the architecture, and that explanation goes some way toward helping you understand the difference between headless and decoupling architecture and what is a headless design system.

Frequently Asked Questions(FAQs)

What is decoupled architecture? 

Traditionally, content management systems use a so-called “unified architecture”, which means that the back-end (where content is created and stored) is tightly coupled to the front-end, sometimes referred to as the “head” (real-time design and presentation). layers).
