Headless CMS has been a rising trend in digital content management for some time, but for some organizations, the reasons may not be quite clear. The headless CMS approach separates content from its presentation, enabling you to display content in any way you want on any channel of your choice.

It is quickly becoming a crucial component of the new digital experience platform (DXPs) generation.

DXPs go beyond web content management to create rich, engaging experiences for audiences across a multitude of channels. And what WYSIWYG (“What You See Is What You Get”) was to the CMS of the 90s, the headless CMS has become for DXPs and future generations of content management.

A full appreciation of the business significance and the need for a headless content management system warrants a more thorough discussion. For a closely related topic, please read the guide: What is a decoupled CMS?

Headless CMS explained in 2 minutes

What is a headless CMS?

A headless CMS is a content management system that manages content without an associated front end or presentation layer. It separates content management (back end) from its presentation (front end).

The headless CMS is not only decoupled; it resides as an API-first CMS where all your content and digital assets are stored. You can use a content API to share your content on different platforms, such as websites, mobile apps, email marketing and CRM.

It is an essential element of a composable architecture and a digital experience platform (DXP), a modular framework of customized software solutions. The headless CMS has an API for the front-end code to retrieve data from the back end. Since they are separate, the back end can make updates without affecting the front end or user experience.

How does a headless CMS work?


A headless CMS is a back-end-only CMS. It has no dedicated front end. So, you store content in the CMS and deliver it to the website, devices or digital touchpoints via APIs. Hence, content in a headless CMS is reusable. So, you can adapt them to various front-end frameworks or content needs.

It is a departure from traditional CMSes like WordPress, where the back end and front end are one and part of the same setup. While such monolithic CMSes restrict how you can display content, a headless CMS does not. In essence, you can look at it as a platform that stores your content, giving you complete control of what you do with it.

Headless CMS vs. traditional CMS

While the all-in-one approach of a traditional CMS might seem straightforward, there is a catch. These systems are not flexible, you are locked into their original design, meaning you cannot scale, adapt to new systems or meet new content needs.

Legacy CMS solutions handle 1:1 content deployment to a single web page. Hence, they cannot handle the omnichannel world of mobile sites, apps, touchscreen displays, Alexa integrations and smartwatch apps.

So, if you want to expand to new channels or scale your content needs, you need your dev team to reconfigure the entire setup. So, while monolithic systems are convenient and quick, you are trapped with only what the system has to offer, which inhibits innovation.

Here is a look at the main differences between headless CMS and legacy CMS:

Feature

Traditional CMS

Headless CMS

Architecture

Monolithic with coupled front end and back end

Decoupled architecture separating content management from presentation

Content Delivery

Single-channel delivery (primarily websites)

Omnichannel publishing (websites, apps, IoT devices)

Development Flexibility

Restricted by programming language and templates

Language agnostic, supports any framework or language

Ease of Use

User-friendly with WYSIWYG editors for non-technical users

Requires more technical expertise to set up and maintain

Scalability

Limited scalability for multi-channel delivery

Highly scalable with independent back-end/front-end updates

Integration

Relies on plugins for expandability

Uses API-driven integrations for greater flexibility

Benefits of headless CMS

The benefits of a headless CMS are immediate and compelling:

  • Streamlined content management: Instead of implementing multiple, parallel content management system instances, e.g., to support web and mobile channels, a single headless CMS instance can serve unlimited digital channels.
  • Flexible and scalable: A single content source, such as a product description for an online catalog, can automatically adapt to its publishing environment and present itself optimally for its destination.
  • Enhanced security: Given that headless content is separated from the front-end layer, it has a smaller surface area of attack. So, imagine there is an attack on the front end, it does not affect your content and digital assets that are lodged in the CMS (the back end). A headless CMS also offers built-in security in the form of a content delivery network (CDN).
  • Ease of use for business users: The separation of code and content in a headless CMS makes life easier for content editors, who can ignore the code and exclusively focus on the content they are responsible for.
  • Better developer experience: Developers, meanwhile, can use all the latest tools and frameworks to bring content experiences to life on any modern platform without being locked into a proprietary language or other limitations of a particular content management system.
  • Cost-efficient: You can reuse content and integrate new channels without reconfiguring the entire system, saving time and cost on development hours. Also, content delivered via APIs is significantly easier to integrate, manipulate and distribute, reducing the time it takes to create content-driven experiences, including sites and apps.

Ever since leading analyst firms identified the headless CMS trend (such as Forrester's report, "The Forrester Wave for Content Management Systems 2023"), enterprises and their IT departments have taken note.

While many websites continue to be well served by the traditional CMS architecture, digital business leaders want to benefit from the improved time to market, the compelling economics and overall efficiencies that headless content management systems offer.

CMS confronts multifaceted digital content consumption

While numerous online platforms have been developed using conventional CMS like WordPress, Drupal or Joomla, the advent of the headless CMS presents substantial advantages for businesses that need to:

  • Expand into new markets
  • Introduce new products and integrations
  • Engage with clients across various interaction points on multiple platforms and devices.

Headless offers some significant advantages that are impossible through most traditional CMS systems.

Why do you need a headless CMS?

The headless CMS is an essential piece of technology because we live in an omnichannel world. The content enterprises create for their website must also appear on apps, integrations, newsletters and more. Managing a duplicate copy of that content for multiple channels is a terrible, inefficient nightmare.

If your company updates how it describes a product, that update shouldn’t be copied and pasted into 20 different systems. You should be able to make the update in one centralized location and push the change out to all places where it matters.

That’s the power of a headless CMS.

It is one central source of truth for all your company’s content and assets. It gives you one place to manage, edit, update and publish that content.

How composable architecture can get you where you want to go

Consumers and users have more touchpoints than ever. Today, running a successful business is not just offering products on multiple channels, such as your website, stores and Amazon. It's more about having a deep customer understanding and orchestrating relevant experiences at the right place and time, regardless of the channel and the touchpoint.

Tomorrow's industry leaders understand the need for business agility that can rapidly transform new opportunities by opening new sales channels and creating new services. A composable architecture — or microservices architecture — delivers this level of agility and scalability. It is based on different services and features divided into agnostic building blocks that can operate independently.

A headless CMS is well-suited to a composable architecture. In a headless CMS, the decoupled front and back end allow content to be reused across multiple channels and devices without rebuilding the entire app. This flexibility gives developers greater control over how content is presented and makes creating seamless user experiences across channels easier.

Beyond the theoretical, many industries and verticals have embraced the headless CMS as a central platform that powers their digital experience across all devices and platforms.
