Headless CMS explained in 30 Sec

A headless CMS separates the presentation layer from the content repository. To sever the tie between content (body) and presentation (head), the content must be structured and thus compatible with multiple clients and technologies.

This makes the content reusable, presented differently on different channels. Developers can build websites and applications using their favorite tools and front-end frameworks, such as Next.js, and use the headless API to fetch content, with presentation handled in the front end.

See us explain headless CMS in 30 seconds:

Why Has Headless CMS Become Popular?

Developer-driven

Headless CMS has become popular because it greatly pleases developers. The headless approach started out serving native apps, but modern front-end frameworks have made it the default for websites too. Developers want to use their preferred framework, and with a headless CMS they can get started right away.

Content for Every Channel

Websites, apps, customer portals, screens, and AI assistants all need content. With a headless CMS, you create content once and deliver it everywhere through APIs, instead of maintaining copies in several systems.

Cloud-based and Scalable

Most headless CMSs are delivered as SaaS, where the vendor runs the platform for you. That makes it easy to grow with new requirements, thanks to scalable architecture and flexible pricing models.

Consistency with Design Systems

A headless CMS integrates well with design systems built using front-end frameworks, letting you achieve a consistent look and feel across your digital experiences.

Ready for AI

Structured content is easier for machines to understand. That helps AI-powered search engines and assistants quote you correctly, and gives your own AI tools clean, reliable content to work with.

Headless CMS Advantages

Front-end Freedom

Headless is all about flexibility. You are no longer locked into a CMS-specific programming language or templating engine. You can build front ends and solutions with the frameworks and technologies you prefer, fetching content as raw data.

Future-proof Digital Experiences

Because the front end of your website or app is decoupled from the content repository, you can adjust and redesign solutions without interrupting the editors who create and manage content at the same time.

Better User Experiences

Freed from back-end structures and forced couplings between content and presentation, developers can focus on building even richer digital experiences for the end user. At the same time, editors can concentrate on creating the best possible content, without worrying about how it will be presented in different channels.

Smoother Upgrades

Decoupling the CMS from your own implementation makes upgrades easier. As long as the API is backward compatible, the CMS can be upgraded without changing your front ends—and vice versa. With a SaaS CMS, the vendor handles platform upgrades for you.

Headless CMS Challenges

We will split the challenges in two, one set for developers and another for content editors. We start with the developers:

Increased Code Complexity

A headless CMS can be lighter and faster than a traditional CMS, but some of the complexity shifts to the developer. Things that used to come out of the box, like rendering logic, routing, and templating, now have to be built in the front end. With headless, you technically start off with an integration, just to make a simple web page.

Accordingly, developers take more responsibility for the project and maintain a larger code base. Starter kits and ready-made integrations for frameworks like Next.js can reduce this considerably, so check what your vendor offers.

More to Host and Operate

With headless, you deploy and host your front end, and possibly additional back-end logic, alongside the CMS. Hosting means taking responsibility for security, scaling, and upgrades.

A fully managed SaaS CMS takes the CMS part of that off your hands: the vendor runs, monitors, and upgrades the platform, and you focus on your front end. Look for a vendor that keeps its APIs stable and backward compatible, so upgrades happen without breaking your solutions.

Challenges for content editors include:

Poor Editor Experience

Many headless CMSs are essentially a database with an API and a set of forms. Editors used to visual page editors may be in for a surprise. When forms are the only editing blocks, it’s hard to build landing pages and manage larger structures.

Complex and Limited Preview

With no tie-in to a front end, content doesn’t always have a meaningful preview. Developers can integrate a preview or create a generic one, but preview tends to be cumbersome and may not show the full context.

No Structure to Navigate

Many headless CMSs store content as flat lists, with no hierarchy that reflects your website. Hierarchies are also useful for management, since you can organize content by team or department and apply more granular permissions and access control. Without such a structure, URL management will likely be a chore as well.

How to Get Headless without the Drawbacks

None of these challenges are reasons to avoid headless. They are things to check when you choose a vendor. Look for:

• Visual page editing that works with your front end, so editors can compose pages without asking developers for help.
• Real preview, showing content as it will appear in your own front end.
• A content hierarchy with permissions, for site structure, URLs, and access control.
• Support for custom APIs and back-end logic, so integrations and scheduled jobs don’t need servers of their own.
• A fully managed SaaS option with stable APIs, so your team doesn’t have to run the CMS.
• Structured content and AI built in, so your content is ready for new channels and AI tools.

Where Enonic Fits

Enonic is a headless CMS built to solve both sides of the equation: front-end freedom for developers and a good experience for editors. With Enonic XP8 and Content Studio 6, you get:

• A Page Builder for any front end. Editors can compose pages visually, even when the site is built in a framework like Next.js.
• Pluggable preview. Editors see their content as it will appear in your own front end.
• A content hierarchy. Content is organized in a structure with granular permissions, which makes sites and URLs easy to manage.
• Universal API. Developers can build, secure, and expose custom APIs, alongside GraphQL for content.
• AI built in. Subscription customers get Juke, the AI assistant that writes, edits, and translates content field by field.
• Fully managed SaaS. Enonic SaaS runs the platform for you, hosted in the EU/EFTA by an ISO 27001-certified European vendor. Compare the plans »
