Navigating the CMS Landscape – Coupled, Decoupled, or Headless CMS?

In today's ever-evolving digital landscape, one of the decisions many businesses are grappling with is choosing a coupled, decoupled, or headless content management system (CMS).

While these all facilitate managing content and information on websites, there can be a range of usability tradeoffs that companies must consider before determining which solution is right for them and how CMS will support your business goals now and in the future.

Before making a decision, it is important to consider the benefits and drawbacks of coupled, decoupled, and headless architectures.

What is a Coupled CMS?

A coupled CMS combines the backend and frontend into a single application. You will find the CMS code, the content repository, the backend editor interface, and your custom code all bundled together.

Figure 1. Diagram illustrating the architecture of a coupled CMS.

This architecture is used by most traditional CMSs.

Here are some pros and cons of using a coupled CMS:

Pros

• Simplicity

  Both the frontend and backend are integrated, so there's only one environment to manage.
• Efficiency

  The built-in themes and templates make it easy to add new landing pages.

Cons

• Omnichannel
  
Limited content types and delivery channels.
• Frameworks

  A programming framework is limited to one.
• Security

  A public server exposes CMS code, which increases security risks.

Use Cases that cannot be covered by a Coupled CMS

Many modern applications and channels cannot get the data they need from a traditional content management system.

The following use cases require either bespoke solutions or a headless CMS:

• Native Mobile Apps (iOS, Android)
• Delivering the same content to a website and an application from the same source (omnichannel/multichannel)
• Voice apps
• AR applications
• VR applications
• Choosing the frontend first and the CMS second. In the case of using a new Javascript framework (Vue.js, React), you would have a difficult time adapting a traditional CMS in order to make it work in your situation.
• Static website generators (e.g. Gatsby, Hugo, Jekyll, Middleman)
• Improve product information on eCommerce sites

What is a Decoupled CMS?

Decoupled CMS decouples or separates the backend and frontend into two systems. The backend app allows content creators to create and manage content independently. At the same time, the fronted system consumes data via an application programming interface (API). By consuming data via API, it is possible to customize any frontend framework and deliver content to any device or channel. The front-end and backend are hosted and maintained separately.

While the frontend and backend work independently, the frontend is predetermined with a specific delivery environment (such as .Net or Angular). It is important to note that these two systems are closely linked and can function as one.

Here are some pros and cons of using a decoupled CMS:

Pros

• Security
  
Separation of front-end code from the CMS.
• Flexibility
  
It is possible to deliver content using a specific delivery environment.
• Integration

  New technologies are easily integrated.


Cons

• Complexity

  Frontend and backend are decoupled. Maintaining two systems independently requires more skills.
• Customization 

  Design work requires front-end development.

What is a Headless CMS?

A headless CMS separates back-end content management from front-end templating and design. The presentation layer is more flexible as it eliminates the front-end part. An application programming interface (API) is used by a headless CMS to deliver the content, allowing it to be accessed and displayed by any device or platform.

As a result, the content can be easily repurposed and displayed in various formats without being tied to any particular presentation layer. By using a headless CMS, businesses are able to revolutionize their digital presence by launching fresh content more quickly and effectively. Staying ahead of the competition is made possible by this innovative approach.

Here are some pros and cons of using a headless CMS:

Pros

• Flexible frontend

  Any technology can be used for any platform, whether it be for native apps, VR, IoT, IoT-based devices, etc.
• Flexible staff
  
Your goal is to hire the most talented developers possible. You don't need to learn a prehistoric template language just to manage your content. Regardless of the language stack your team chooses, you can work with it.
• API consistency

  Content creation for each platform can be complex and time-consuming. With a single, unified API, you can significantly reduce overhead and development operations, making accessing content easy and affordable.
• Reliability separation
  
The separation of the presentation layer from the CMS code is clearly defined, without having to interfere with any CMS code.
• Scalability and security
  
It provides high levels of security and a greater degree of scalability.

Cons

• Cost of development

  There may be limitations for marketers since they may need to rely on developers for scenarios like building landing pages with custom layouts.
• Content Preview
  
In-page editing and live previews are difficult to see without significant development assistance.

Which One to Choose?

When choosing the right CMS, you should focus on understanding its features, consider the changing digital landscape, and prepare your business for the future. As you can imagine, many options are available these days, so why would a Headless CMS be the better choice for so many people?
