What is a Headless CMS: a Visual Guide

Last updated: August 30, 2023

In today’s fast-paced digital age, content management systems (CMS) have become essential tools for efficiently managing and delivering content across various platforms. Among the various CMS options available, the concept of a headless CMS has emerged as a powerful and flexible solution.

What is a CMS?

A content management system (CMS) is a software platform that enables users to create, edit, organize, and publish digital content, such as articles, images, videos, and more.

CMSs have long been the backbone of digital content creation and delivery. Traditional CMS platforms, including open-source solutions like WordPress, Joomla, and Drupal, have been popular due to their ease of use and integration of content creation and presentation.

Here's a visual representation of a traditional CMS:

A traditional CMS operates as a monolithic application. All of the different functions, such as content creation, storage, and delivery, are tightly integrated into a single system. Users use a WYSIWYG editor within the admin interface to create and oversee content, which is subsequently transformed into a responsive user interface that adapts to various devices.

However, the tight coupling of content creation and presentation in traditional CMS brings about several challenges. One of the main issues is the lack of flexibility when it comes to delivering content across websites, mobile apps, IoT devices, smartwatches, and any emerging technologies.

Each platform often requires specific content formatting and delivery mechanisms, which means content must be managed separately for each touchpoint. This not only creates inefficiencies but also leads to maintenance problems and inconsistencies in user experiences. The need for a more flexible approach gave rise to the concept of CMS with a headless architecture.

What is a headless CMS?

At its core, a headless content management system decouples the content creation and presentation layers. Unlike traditional CMS platforms, a headless CMS does not enforce a specific front-end presentation (the "head") for displaying content.

Instead, it provides APIs (Application Programming Interfaces) that help developers fetch from a single content source and deliver data to any desired front-end, such as websites, mobile apps, IoT devices, and more. Moreover, the headless CMS often provides both RESTful API and GraphQL API options, ensuring versatile and efficient content fetching capabilities.

Here's a visual representation of a headless CMS:

In contrast to traditional monolithic setups, a headless CMS adopts a composable app approach. In this approach, various functionalities such as content creation, external integration, and delivery function independently yet cohesively.

Users engage with a simple data editor to efficiently create and manage content. This content then undergoes a seamless transition into content APIs, which can be used by a technology of choice.

Headless CMS: an analogy

Think of a traditional CMS as comparable to purchasing a frozen pizza — it's convenient but confines you to ready-made choices. In contrast, a headless CMS is like having a fully stocked kitchen complete with fresh ingredients at your disposal.

Imagine crafting not just a pizza, but also experimenting with gourmet pasta dishes or crafting delectable calzones using different techniques and flavors from the same box of ingredients. Such is the potential of a headless CMS.

How a headless CMS works

A headless CMS functions through a straightforward yet powerful process.

  1. Content creation and management: Content creators and administrators use the headless CMS interface to create, edit, and organize content, including text, images, videos, metadata, and other media assets.
  2. API-based architecture: The headless CMS stores content in a database and exposes it through APIs, so developers can programmatically retrieve structured content, such as JSON or XML.
  3. Front-end development and consumption: Developers build front-end applications that interact with headless CMS APIs so that the front-end can retrieve and display content based on design and user experience requirements.

Benefits of a headless CMS

Using a headless CMS comes with a plethora of advantages:

  1. Future-Proofing: The decoupled CMS nature provides easy adaptation to emerging technologies and changes in the digital landscape.
  2. Flexibility: Developers can implement unique user experiences using any tech stack; next.js, gatsby, vue.js, or react, to name a few. This allows for more creativity and customization.
  3. Better Performance: Thanks to optimized front-end design, API-driven content delivery, and integration with CDNs (Content Delivery Networks), sites and apps using a headless CMS improve loading times.
  4. Scalability: Independent scaling of front-end and back-end ensures better performance and handling of traffic spikes.
  5. Collaboration: Content creators and developers can work independently, promoting seamless collaboration and faster iteration cycles.
  6. Content Reusability: A single content repository enables repurposing content across multiple platforms and devices, such as websites, mobile apps, smart devices, and more.

Who's using headless CMSs

Headless CMS is embraced by diverse industries and organizations that value agility, customization, and seamless cross-platform content delivery.

  1. Developers and agencies: Web developers and digital agencies often use headless CMS because it allows them to build custom front-end digital experiences for their clients. They have the freedom to choose the best technologies for the job and create highly tailored and unique websites or applications. They can also optimize better for SEO.
  2. E-commerce businesses: E-commerce platforms often use headless CMS to manage product information, marketing content, and other relevant data. With a headless CMS, they can easily deliver content to multiple channels, such as websites, mobile apps, voice assistants, and other devices to deliver excellent customer experiences for the end user.
  3. Media and publishing companies: Companies that handle a large volume of content, such as news outlets, blogs, and magazines, use headless CMS to streamline their content management processes. The decoupled architecture allows them to distribute and reuse content across various platforms efficiently.
  4. Marketing teams: Marketing teams can use headless CMS to manage marketing content, landing pages, and promotional material across different platforms without relying on IT teams for implementation.
  5. Mobile app developers: Headless CMS helps mobile app developers to manage app content without needing frequent updates through app stores. The same content can be delivered to users in real-time without requiring app updates.
  6. Many others: Headless CMSs are popular in many industries such as education, government agencies, startups, and virtually anyone with sites and apps to maintain.

Drawbacks of a headless CMS

One major challenge of a typical headless CMS is the lack of a visual interface for finding and editing content. This can create difficulties in:

  1. Locating the required content to edit
  2. Intuitively previewing and editing your content
  3. Making non-trivial changes without needing engineering assistance and deployment
  4. Testing and personalizing content
