Headless CMS 101: The Only Guide You'll Need

For the longest time, traditional monolithic Content Management Systems (CMS) like WordPress, Drupal, and Joomla, which couple the frontend and backend together, were the go-to approach for managing website content. However, with the rise of new technologies and the need for more flexible and scalable solutions, a new type of CMS has emerged: the Headless CMS.

In this ultimate guide, we will dive into the Headless Content Management System world, learn how it works, the types of CMS, its benefits, use cases, factors to consider when choosing one, and much more. Let's dive in!

Headless CMS glossary

Headless architecture

Headless architecture is a contemporary web development approach that divides the frontend, the part of the system that users interact with, from the backend, which houses all of the data and logic. It entails separating the "head" (frontend) from the "body" (backend).

API-first

API-first means designing and building an application's backend infrastructure with APIs as the primary focus. Traditionally, developers would first build the user interface (UI) and then create APIs for the frontend functionalities. However, with the API-first approach, developers start by designing and developing APIs.

Multichannel content delivery

Multichannel digit content delivery is the practice of distributing content through multiple digital channels. The benefits of implementing a multichannel strategy include:

• Increased market reach and audience engagement
• Diversified content distribution channels
• Enhanced brand and content visibility
• Brand consistency

What is a Headless CMS?

A Headless Content Management System is a content management system that focuses solely on content creation, management, and delivery without the constraints of a built-in presentation layer. Unlike traditional content management systems, which combines the content management and presentation layer into a single system, a headless CMS decouples these layers, allowing for greater flexibility and scalability.

In a headless architecture, the CMS acts as the backend and provides a user-friendly interface for creating, managing, and publishing content like text, images, videos, and documents. On the other side of things, a developer handles the frontend, or "head," where the content is displayed and rendered. The frontend could be websites, mobile apps, other digital experiences, signage, etc.

Due to this separation of contents, a headless CMS takes the API-first approach and uses APIs to facilitate communication between the presentational layer and the content repository. This provides several core features:

• Content creation and editing
• Content organization and structuring
• User roles management
• Content creation workflow management
• Version control
• SEO optimization
• Starter templates.

Types of headless CMS

API-first CMS

An API-first CMS, like Prismic and Contentful, serves your content via a REST API or GraphQL API. This type of CMS provides maximum flexibility in managing content and delivery.

Features

• Supports integration with various frontend technologies like Next.js and Svelte.
• Provides content and media asset management functionality.

Pros

• Provides greater flexibility over the design and look of the presentation layer.
• There are no content delivery limitations, as content can be distributed to any frontend via APIs.

Cons

• Requires developer expertise for proper implementation.
• Increased costs as you experience higher traffic on your website.

Use case: Ideal for teams that want full control over the presentation layer and need to serve content to multiple touchpoints like websites, mobile apps, and IoT devices.

Git-based CMS

A git-based CMS, like Netlify CMS, uses Git, a version control system, to manage and track changes to content. It allows developers to manage their content in a Git repository, providing all the benefits of Git for version control in content management.

Features

• Supports Git-based workflows like version control, branching, merging, and rollbacks.
• Content is written in text-based files like Markdown.

Pros

• Developers can use their preferred code editors and IDEs to manage content.
• Content is stored in local repository files, allowing developers to freely migrate content from one CMS to another.

Cons

• Limited support for non-technical users.
• Requires knowledge of Git.

Use case: Ideal for developers who enjoy the Git-based workflow that involves branching, merging, and rollbacks.

Self-hosted CMS

Instead of relying on the third-party vendor's hosting, a self-hosted CMS, like Strapi, gives you full control over your CMS's server, cloud installation, and configuration.

Features

• Ability to deploy on-premises, on your favorite public cloud, or the PaaS of your choice.
• These are mostly open-source CMSs that give you access to the code base and allow you to make customizations to fit your needs.

Pros

• Greater flexibility and potential cost savings.
• Provides greater control over your data by allowing you to host it on your own servers or cloud environment.

Cons

• Takes time to set up.
• Requires technical expertise to set up and maintain.

Use case: This type of CMS is appropriate for businesses that have strict security and compliance requirements, have a DevOps team they can dedicate to the project, and prefer to have complete ownership and control over their data.

Benefits of a Headless Content Management Systems for businesses

Improved scalability

Why it is important: As your business grows, so do your audience and content needs. You'll need a CMS that can handle your expanding website traffic and amount of content.

How it delivers: Scaling is much easier with a headless CMS, as you can scale the backend independently from the frontend because they are decoupled. This means you can handle high traffic volumes without compromising performance or user experience.

Shorter development times

Why it is important: A faster time-to-market is important for staying competitive and launching new campaigns, landing pages, and apps. You need a system that allows you to ship fast.

How it delivers: With the headless approach, development and content teams can work independently and in parallel. This approach speeds up development cycles and eliminates delays.

Meet your audience where they are

Why it is important: The customers of this modern age consume content through different digital platforms like phones and wearables. It is important to reach them where they are and ensure a consistent messaging and experience.

How it delivers: With headless content management system, there is no limit to the types of channels you can distribute your content to. Potential delivery channels include any digital touchpoint that supports communication with APIs, such as: Websites, Mobile apps, Digital and signage.

Future-proofing

Why it is important: Technology is constantly evolving, which means that you need a CMS that allows you to adapt to emerging technologies.

How it delivers: A headless CMS allows you to stay at the forefront of innovation and remain competitive. Is there a new frontend framework that's proven to be 100 times faster than the alternatives, or are you looking to target customers through a new digital channel? You can make a switch and stay up-to-date with the latest innovations. The best part is that you don't need to make any changes to your content or CMS to achieve this.

Improved developer experience

Why it is important: With a traditional CMS, developers are limited to working with the tools and technologies the CMS supports.

How it delivers: A headless CMS provides greater freedom and tech stack flexibility and allows you to choose your preferred javascript framework, whether Vue, Nuxt, React, Next.js, Svelte, Sveltekit, etc. This can enhance productivity and enable faster development.

Single source of truth for content for multiple platforms

Why it is important: Before headless CMSs emerged, content teams had to create duplicate content for the different delivery channels. This inefficient content management workflow led to inconsistencies and was a nightmare to manage, particularly for large-scale projects.

How it delivers: A headless CMS stores content in a central repository and uses APIs to deliver the content to as many frontends as needed. This “create once distribute everywhere” system streamlines content management by providing a single source of truth.

Eliminates manual software updates

Why it is important: Traditional CMSs often require extensive IT resources to manage software and plugin updates. Not only is this time-consuming, but it can also introduce security risks if not performed regularly.

How it delivers: With a headless CMS, you don't have to worry about performing manual updates because the content management system provider handles them. This means that your software remains up-to-date, automatically gets the latest upgrades, and remains secure, all while leaving you to focus on core business activities.

Improved SEO performance with Static Site Generators

Why it is important: If content is king, then SEO is the kingmaker. It doesn't matter how great your content is if your target audience can’t see it. Websites built with traditional CMS often suffer from low loading times because the browser needs to simultaneously load the code for the backend, frontend, and content.

How it delivers: A headless CMS addresses these issues by decoupling the frontend and backend and delivering the content via a Content Delivery Network (CDN) for optimal performance. It also allows you to work with frameworks and static site generators like Next.js that offer server-side rendering and static site generation capabilities. This further improves SEO performance by allowing bots and web crawlers to detect metadata and index web pages.

Scenarios where a headless CMS is the best choice for your business

A headless CMS has several benefits, as we have seen. However, that doesn't mean headless architecture is always the best approach to follow. Here are some scenarios that call for using a one.

• When your frontend requires a unique and creative design: There are limits to how creative your frontend can be when working with a traditional CMS. On the other hand, a headless CMS gives you full control over the presentational layer, allowing you to make it as wild as possible. Check out examples of some unique websites businesses and developers have built with Prismic; this is one of my favorites.
• If your development team requires greater flexibility: If your developers are restricted from working with the latest technologies that allow them to do their best work, it may be time to switch to a headless CMS.
• When you want to reduce the risk of cyber attacks: Traditional CMSs are at risk of threats like DDoS attacks due to the coupling of the frontend and backend and the large number of plugins and extensions they provide. However, headless CMS eliminates these risks by decoupling the frontend and backend.
• When you want a single source of truth for your content: With a headless CMS, you can create a piece of content once and use the APIs to deliver the content to your chosen digital touchpoints.
• When you want unrestricted market reach: With a traditional CMS, there is a limit to the number of platforms you can deliver your content. This affects your market reach, particularly if your target audience uses next-gen platforms. However, headless CMS has no restrictions, allowing you to meet consumers where they are.
• When your current content update process requires multiple copy and pasting: If you currently have to copy and paste content changes across 20 frontend layers, that is a strong indicator that you need to switch to a headless CMS for your content management needs. You get one source of truth, and any changes made to the content automatically appear on all frontends, no matter how many.

Headless CMS use cases

A headless CMS can be used to build a wide range of projects across various industries. Here are some common headless CMS use cases.

Marketing websites and landing pages

With a headless CMS, you can create marketing websites and landing pages for marketing campaigns, product launches, and special events. The best part is that you can update the content as needed.
