But before that, let’s understand what headless CMS solutions are and how using them makes total sense.
What is Headless CMS?
A Headless CMS is essentially a Content Management System (CMS) with only a backend system, a database to store files, and an API for content distribution. It has no frontend system, hence the name “headless”.
But if you are not familiar with CMS, it’s a system or a software solution used to manage content. It allows you to easily create, store, manage, and modify your content. Even if you don’t have any coding or technical expertise, you can build a website and start publishing content straightaway using a good CMS, such as WordPress, Wix, Joomla, etc.
Coming back to the topic, headless CMS systems manage content without a presentation layer or frontend; instead, the content stored in it is distributed via API calls across devices and platforms.
How does Headless CMS work?
Traditional CMS systems use a monolithic architecture where frontend and backend systems of an application or site are connected in a simple fashion. This means it includes both – the site’s presentation layer, i.e., the frontend as well as the backend where the content is stored.
Let’s understand this by taking WordPress as an example. Its frontend is restricted. Although you can tweak some changes through templates, icons, etc., you can’t completely change it. It also limits content operations, design, optimization, and performance.
Headless CMS helps here by removing the “head” or frontend entirely. It purely runs on an app’s backend and attaches the frontend through API. This way, developers have the full flexibility to deliver content anywhere.
It’s named “headless” as in – a body with no head, where:
Frontend = Head
Backend = Body
CMS architecture = Frontend + Backend
So, a headless CMS stores your content and uses an API to distribute the content anywhere you want, such as websites, tablets, mobile devices, CRMs, smartwatches, etc. It is actually a more flexible form of CMS that also eliminates the need for hosts; hence, maintenance becomes easier with increased productivity and collaboration.
What are the benefits of Headless CMS for modern businesses?
Separating frontend and backend parts of a system allows you to use the backend just for storing, organizing, and managing content while leaving the frontend part to distribute content for a specific channel. This offers many advantages to the developers and publishers.
Increased flexibility
Unlike traditional CMSs with plenty of limitations, headless CMSs are more flexible. The former puts everything – content, CSS, and HTML in a single place, making it difficult for you to reuse the content.
In contrast, headless CMS offers higher flexibility of design, performance, and distribution by separating the frontend and backend and distributing content through APIs. Your developers can work with multiple frameworks, tools, and technologies of their choice without worrying about content, which will be published independently. You can also design your own frontend however you like and spend time creating more content.
Scalable
You can manage content easily from a point and make changes to your frameworks, tools, and languages without affecting your content. In addition, using the cloud-based architecture will also let you scale up and down easily without any hassles. You can even customize your site without allowing downtime.
Excellent compatibility
Headless CMS systems are compatible across devices, platforms, and technologies of modern times. So, you can easily publish your content anywhere you like with consistent performance. In addition, you can integrate with multiple languages and codebases to make things simpler.
Better security
Since you are separating the frontend and backend, even if one of them is compromised, it won’t affect the other. This offers better security than traditional systems where both parts are combined. In addition, it enables a single point of contact between your technology stack and content through API; hence, the attack surface reduces significantly.
Easier maintenance
Removing the frontend will make it easier for your team during maintenance. This reduces the need for less workforce, time, money, and other resources and improves collaboration between your team since they can share things easily.
Looking at the impressive benefits of headless CMS, it makes sense to transition from traditional CMS and embrace the modern, efficient architecture of headless CMS systems. And if you are looking for it, you will find plenty, each with excellent features. However, many of them are paid for advanced features, which everyone might not require.
