What is Headless CMS Software?

A headless CMS, also known as API-first CMS, is a back-end exclusive content management system where the content repository “body" is decoupled from the front-end presentation layer. The architecture of a headless CMS differs from traditional CMS architecture. Instead of a static front-end display, content is pulled from the repository via a RESTful API (web services that implement a REST API), which allows it to be displayed on any type of device. Since content is pulled from a RESTful API, the front-end presentation is generated on the end user’s side and developers can create digital experiences without creating bespoke front-end displays for different types of devices. The ability to avoid the development of unique, device-specific front-end displays is the main purpose of a headless CMS. Traditional web content management systems (WCMS), also known as monolithic CMS, struggled in this regard, and developers were often tasked with creating multiple, device-specific user interface displays for their websites and other digital experiences. While some traditional B2B CMS are advertised as being mobile friendly and ready to be viewed on mobile apps, many are unable to take into account all the types of devices a web page could be viewed from, including smartwatches, smart TVs, gaming consoles, and other internet of things (IoT) devices. Since a headless CMS is entirely device agnostic, it can deliver and format content to any of the above devices and more. With a headless CMS, developers can develop as many front-end layers as they would like in whatever coding language they prefer. Further, because the back-end is decoupled from the front-end, headless CMS allows for real-time editing and collaboration. Decoupled content management systems are also discussed alongside headless CMS; both have similarities, but the differences are stark. Both headless and decoupled content management systems separate the back-end content repository from the front-end presentation layer of a website or application. However, a decoupled CMS will provide traditional WCMS features like content templates and what you see is what you get (WYSIWYG) editors to create front-end content experiences. This can be beneficial for marketers who may find headless CMSs too technical to use for publishing content. What Does Headless CMS Stand For? Headless CMS stands for headless content management system. A content management system is a software application that manages web content and allows multiple contributors to create, edit, and publish content. In a traditional CMS, the content is stored in a database and users can select templates and extensions to design and customize the front-end. Headless CMS is a type of content management system that only deals with content. Once the content is created, it is published through an API. What Types of Headless CMS Software Exist? Headless CMS providers offer the same core features across most solutions. There can be variation in functionality if the headless CMS is part of a larger software solution like a digital experience platform (DXP), but most standalone options are very similar. The key difference between headless CMS solutions is how they are licensed. Headless CMS, like many other content management systems, are either open source or software-as-a-service (SaaS) solutions. Open source Some headless CMS options are completely open-source software solutions, meaning developers can access the source code if need be. Open-source content management systems are easier to customize and tailor to a business’ needs. Since open-source software can be modified, developer communities tend to build around them, allowing programmers to collaborate and solve problems together. Open-source solutions are great options for developers looking for community support and collaboration for their software of choice. SaaS Many headless CMS options are available as SaaS products that can either be hosted in the cloud or on site. In either case, SaaS solutions require a license to use, so businesses must purchase the product. Since the software is licensed, developers won’t be able to modify the source code. However, one key benefit of SaaS headless CMS options is their focus on business use cases, and typically SaaS headless CMS options provide some specific, predefined modifications so businesses have some customization options. Another benefit to SaaS solutions is access to vendor-provided technical support—something open-source solutions very rarely have.

What are the Common Features of Headless CMS Software?

The following are features that make managing content using a headless CMS efficient for an organization. RESTful API: REST stands for representational state transfer, an architectural style for communications utilized in web services. An API is a set of procedures or functions that allow programmers to access features or data of an application, operating system, or database within their application. A RESTful API uses HTTP calls to GET, PUT, POST, and DELETE resources from a content repository. A RESTful API is the backbone of a headless CMS. Without it, device and channel-agnostic content delivery wouldn’t be possible since developers would need to create bespoke front-end layers for every device and channel. With a RESTful API, how content should be displayed is already built into the code and isn’t dictated by a static presentation layer. Editor interface: Like other web CMS software, a headless CMS provides an editor interface or dashboard where users can draft content, upload and manage assets, and view different project layers. Content repository: A core component of a headless CMS is its content repository. The content repository houses all content that will be delivered through a website or application via the RESTful API, including written content, images, video, and audio files. Content taxonomy and tagging: A headless CMS often provides a comprehensive taxonomy and tagging system for content added to the content repository. This provides structure to the content repository for ease of navigation and simplifies reusing assets. Versioning: Headless CMS options also provide content versioning akin to versioning features in other content management systems. This feature allows content authors to keep track of changes and revert edits to content if the need arises. User permissions: User permissions features allow administrators to designate access to specific features or permission to view and edit particular projects and content. Permissions and roles are standard features in content management systems, including headless CMSs. Every user working within a headless CMS does not need access to every project or piece of content; locking specific features or access to content is a practical solution to ensure security and prevent mistakes. Workflows: Many headless CMS providers provide built-in agile workflows to enhance efficiency within the application. This allows teams to delegate tasks and keep track of the different stages of a project. Other features of headless CMS software: AR/VR Capabilities, Content Performance, Form Building, and Unlimited Environments.

What are the Benefits of Headless CMS Software?

Multi-platform and omnichannel content delivery: A headless CMS allows for omnichannel content delivery, meaning that it gives companies the ability to distribute content to users through various channels and build a cohesive user experience across multiple platforms. A headless CMS streamlines operations and allows for content management to occur from a single location, making content optimization and delivery efficient. Flexibility for developers while developing front-end layers: Using a traditional CMS structure can be extremely limiting for developers because the front-end layers are dependent on the back-end, meaning that there needs to be separate code for each type of device that the content will be displayed on. With a headless CMS, the front-end presentation layer is decoupled from the content repository, giving the user freedom to build a front-end framework that makes sense for the project. Headless CMS allows users to focus on content creation as opposed to content management, allowing for more freedom and scalability.
