Headless CMS: Everything you need to know

Key Takeaways

• A headless CMS is a backend-only CMS that provides a "Content Repository" that makes content accessible to any platform or digital channel via an API.
• Unlike a traditional CMS such as WordPress, a headless CMS does not dictate where or how content is shown.
• A headless CMS enables teams to deliver omnichannel experiences at scale, globally, without being restricted by templates or pre-defined technologies.
• A headless CMS enables developers to use their preferred tech stack or framework, including popular ones like React, Angular, and Vue.
• Headless CMSs generally provide better ROI since they are cloud-based, security and backups are handled by the vendor, and they are easily scalable, all while reducing time-to-market when delivering projects.
• Specific technical resources are required to migrate to a headless CMS.

Since our founding in 2017, Hygraph has been part of the headless CMS journey, pioneering a GraphQL-native approach.

Fast forward to 2025, the market is crowded with buzzwords and lookalike vendors, leaving teams overwhelmed when moving away from monoliths or switching providers. This makes it vital to return to the fundamentals:

• what headless CMS really is
• why it matters today
• how it can bridge the gap to an AI-driven future

The Hygraph Headless CMS Academy offers guides, use cases, comparisons, and headless cms tutorials to help you navigate this evolving landscape.

What is a headless CMS

A headless CMS is a content management system where the backend (content repository) is completely separated from the frontend (presentation layer). Content is served via APIs to any platform — websites, mobile apps, smart devices, digital signage, and more.

The content is stored in a raw structured format, such as HTML or JSON, and isn't meant for human consumption until rendered on the end device.

Here is an illustration of how headless CMS works.

Headless CMS is the natural evolution of content management

The evolution of CMS mirrors the growth of digital experiences. Monolithic systems worked when websites were the only channel, but as experiences expanded, they quickly showed their limits.

This led to the rise of custom, in-house CMSs, which solved performance and flexibility issues, but at the cost of heavy engineering and hard-to-find expertise.

The popularity of smart devices and the need for multi-channel delivery brought new challenges for content teams — mainly how to deliver content across diverse channels on scale. In the meantime, enterprise companies are looking for solutions that improve efficiency and cross-functional collaboration. This is fueling the demand for headless CMSs: by decoupling the presentation layer from the content repository, developers and marketers can each focus on their core work, while APIs enable seamless content delivery across any channel.

Why headless CMS?

While headless architecture and headless CMSs have been around for a while, their popularity has grown exponentially. If we look at Google Trends over the last few years, we can see that searches for headless CMS is constantly growing.

What's the reason behind this growing interest?

"Headless" has become the popular approach to handling content due to the increasing diversity of platforms that need content, the improved developer experience it offers, among other benefits.

Earlier this year, we interviewed 10 CMS experts about the future of content and identified top 5 content trends:

1. Hyper-personalization is becoming more feasible
2. Omnichannel customers mandate consistent content
3. AI catalyzes new content strategies
4. Site security remains a top priority
5. Data gets harmonized with a unified content layer

Format-agnostic, machine-readable content is not only easier to manage today, but also essential for AI systems that depend on structured data to automate personalization, localization, and predictive delivery.

Benefits of a headless CMS

Everybody talks about the benefits of adopting a headless CMS, but what are the actual pros for you? То make the advantages easier to understand, we’ve listed the benefits by roles.

Here are 20 reasons to use a headless CMS:

For the company and leadership

• Future-proofing and scalability: Separated content and presentation layers make it easier to adopt new technologies, redesign frontends, or expand to new channels without reworking the whole stack.
• Shorter time-to-market: Developers and content teams can work side by side, which speeds up launches and updates. Companies can experiment with new channels and test new opportunities with minimal risk.
• Reduced vendor lock-in: Content is stored in an agnostic, API-delivered format, which makes migrations or provider changes less disruptive.
• Centralized content management: A single, universal repository reduces silos and streamlines operations across departments.
• Security: With the frontend decoupled from the backend, there are fewer attack angles, while you also reduce reliance on vulnerable plugins.

For developers and architects

• Frontend freedom: Developers can use any framework (React, Vue, Angular, Svelte, Astro, etc.) to design experiences without being tied to a monolithic CMS.
• Microservices and composability: Instead of being locked in monolithic feature sets, you can easily integrate together specialized APIs and services for payments, search, personalization, etc.
• Structured, clean data: Clearly defined APIs and data models make querying, filtering, and extending content faster and more reliable.
• Faster prototyping and iteration: Developers can test, deploy, and fine-tune applications without breaking the existing system.
• Simplified upgrades and maintenance: Backend and frontend can evolve independently, avoiding the complexity of plugin/theme updates, which are common in legacy CMSs.
• Team flexibility: Companies can hire developers for modern languages and frameworks instead of having them trained on outdated template systems.

For content editors and marketers

• Omnichannel publishing: You can create content once and publish it across websites, apps, IoT, voice assistants, digital signage, and more — without duplicating work.
• Parallel workflows: Marketers and editors can create and manage content independently of developers, avoiding bottlenecks and delays.
• Future-proof content: Content in decoupled storage can be reused, remixed, or delivered to new channels as they emerge.
• Consolidated repository: Manage all content centrally, with consistency and governance across regions, brands, or product lines.
• Faster campaigns and experimentation: The ability to update, test, and ship out content quickly helps marketing teams adapt to trends and audience needs.

For end users

• Improved performance: Lightweight, API-driven delivery also results in faster load times, leaner pages, and smoother digital experiences.
• Consistent omnichannel experience: Users face unified brand messaging and interactions across web, mobile, apps, in-store, and emerging platforms.
• Tailored and accessible experiences: Structured content and flexible presentation enable personalized, inclusive interfaces that meet rising accessibility and UX expectations.
• Reliability and trust: Improved security and scalability mean less downtime, safer interactions, and smoother experiences even during peak usage.

Types of headless CMS

You’ve likely come across many different ways CMSs are categorized. For instance, the Jamstack site groups them into Git-based, API-first, locale-based, and visual CMSs. Since the list can be overwhelming, we’ve organized the categories in a clearer way.

By storage architecture

• Git-based: These CMSs store content as flat files and integrate directly with your codebase. This allows flexible editing with familiar tools, and easy collaboration, but the delivery is limited to Git-friendly frontends only.
• Database-driven (e.g.Hygraph): Content is stored in a traditional database, queried through APIs. This type allows you to combine the strength of content and data to create personalized experiences.

By hosting model

• Hosted/cloud CMS: The CMS is provided as a managed cloud service, where the vendor handles hosting, updates, and security. The terms “hosted” and cloud CMS can be used interchangeably.
• Self-hosted: The CMS runs on your own servers or cloud infrastructure. It gives full control over customization, deployment, and compliance but demands more developer resources.

By the infrastructure model

• Serverless: A subset of cloud CMSs, where the system automatically scales without dedicated servers. It’s highly elastic and cost-efficient, but it depends completely on the vendor’s infrastructure.
• Non-serverless hosted: Runs on managed servers or virtual machines (VMs) in the cloud. Although scalable, this CMS type usually requires fixed resources and more manual work compared to serverless systems.

By licensing/code access

• Open source: The CMS codebase is publicly available, so your developers can freely inspect, modify, and extend it. Open source CMSs offer a great deal of customization and scalability without vendor lock-in. However, you may need to invest in self-hosting or support services.
• Proprietary: Licensed software owned by a vendor, with limited or no access to source code. These solutions usually come with vendor support, SLAs, and enterprise features, but restrict customization. Pricing is either subscription- or license-based.

SaaS CMS

Most proprietary headless CMSs are SaaS, delivered as subscription-based cloud services. However, keep in mind that:

• Proprietary ≠ always SaaS: Some (e.g., AEM, Sitecore) are licensed software you install and manage yourself.
• SaaS ≠ always proprietary: Some SaaS products (e.g., Strapi Cloud) are built on open source. SaaS is generally a better choice for teams that want low-maintenance, cost-predictable, and automatically updated CMS solutions.

API-first CMS

While not all headless CMSs are API-first, an API-first CMS can be seen as a subset of headless. An API-first CMS is built from the ground up to deliver content via APIs (REST, GraphQL) rather than as a web page. Structured content and integration with other services are the core features here, making this CMS highly flexible for omnichannel delivery.

Challenges of headless CMS

While a headless CMS offers numerous advantages, many organizations are skeptical about adopting one. That's because not every headless CMS offers the hybrid features that modern enterprises need.

Some of the potential challenges include:

No frontend

A headless CMS solution doesn't come with a frontend. So, whether you want to create content for a website or another channel, you need frontend developers to build something from scratch. Without adequate developer resources, this can end up being time-consuming and expensive.

No drag-and-drop page building experience

With a headless CMS, there is a paradigm shift from a drag-and-drop approach to building content components pre-built on the frontend. This may look intimidating at first, but it brings a great deal of benefits in the long run. Hygraph empowers content creators and offers a rich editing experience, including versioning, previews, content staging, and more.

Developer dependencies

While pre-built frontend components work great for the ongoing work, at times when something new is required to be created it would have to be done by the frontend team.

How headless CMS works

A headless CMS works by separating content creation from content delivery, which makes the whole process faster, more flexible, and easier to scale.

On the technology side, all content is stored in a structured database, defined by schemas and content models that ensure consistency.

Instead of being locked into rigid templates, content is delivered through APIs (REST or GraphQL) that fetch exactly what each frontend — a website, mobile app, or smart device needs.

This decoupled architecture results in leaner code, faster load times, and higher performance, since the frontend is optimized independently from the backend.

On the operational side, developers are free to build with their preferred frameworks while focusing only on the user experience, without worrying about how content is managed.

Content editors, at the same time, work in a clean, central hub, where they can create, update, and publish without relying on developers.

Such a parallel workflow eliminates bottlenecks, shortens time-to-market, and keeps projects adaptable.

The result is a content management system where marketers save time, developers innovate freely, and end users enjoy faster, more consistent digital experiences across every channel.

How does headless CMS empower modern team collaboration

A headless CMS improves collaboration by giving both developers and editors the freedom to focus on what they do best, without stepping on each other’s toes.

For developers, decoupled architecture means no more firefighting small editorial requests — they can concentrate on building modern frontends, integrating new tools, and keeping the system scalable.

Features like roles, permissions, and workflow automation further streamline collaboration, letting developers shape the architecture while editors safely manage content.

For editors and marketers, headless removes the reliance on developers for routine updates — been there, done that!

Once the schema is set, editors can create, publish, and reuse content across channels independently, confident that design consistency is enforced by predefined components.

Free from routine maintenance, Alex can focus on building a new feature, while Maria doesn’t have to wait on him to tweak a carousel or re-code homepage links.

Together, this shift creates an optimized, future-proof collaboration model: editors focus on content quality, developers innovate on technology, and the business benefits from faster time-to-market, reduced costs, and a smoother user experience.

Headless CMS is the future of content management

Headless CMS has moved beyond managing pages — it’s now the backbone of digital experience. By decoupling content from presentation, it allows brands to deliver seamless experiences across every device and channel, while scaling effortlessly.

Today, headless platforms are evolving into digital experience ecosystems that integrate analytics, personalization, and commerce into a composable stack.

Instead of relying on rigid monoliths, leading organizations are building modular, best-of-breed architectures — with the headless CMS at the center of their digital strategy.

Frequently Asked Questions

What is a headless CMS?

A headless CMS is a content management system that provides a way to create, edit, and deliver content to one or several frontends. Instead of having your content tightly coupled to a particular frontend (like a website or mobile app), it provides your content as data over an API to be served to any frontend.

What does headless mean?

Headless means that the application is running without a graphical user interface (GUI) and sometimes without a user interface at all. The frontend (head) is detached from the backend (body), allowing both to be developed independently.

What are some other terms for headless CMS?

Headless CMS may commonly be referred to as Content Database, Content Backend, Content Repository, or Content API. It is essentially a backend-only content management system that acts as a content repository, and makes content accessible via an API for display on any device, without controlling the presentation layer(s).

What is a headless Website?

A headless website is built using a headless CMS, where the content is served via API from a backend rather than a classical “web CMS.” When needed, the same content can be distributed to multiple websites, apps, and other digital platforms.

How do you use a headless CMS?

To use a headless CMS, you must build a frontend (website or an application) first, then use the CMS's API to query and serve your content. This is in contrast to “creating your content on the website” as in the case of page builders and classic Web CMS.

Is a headless CMS just an API?

The short answer is no. A headless CMS is more than just an API. While headless CMSs provide APIs to connect the frontend with the backend, they also provide user-friendly interfaces for content editors and content management features like content workflows, version control, role-based access control, and more.

Is a headless CMS just a database?

No, a headless CMS is not just a database. While it stores and retrieves content like a database, it also offers a user interface (UI) and content management features. Headless CMSs allow you to use a separate database of your choice if needed, but they also provide APIs to connect with various frontends.

Is a headless CMS a backend?

Headless CMS is part of the backend. However, it does not replace the entire backend infrastructure. While it handles content storage, management, and API-based delivery to various frontends, it typically works alongside other backend systems like Product Information Management (PIM), authentication services, and business logic layers to form a complete backend ecosystem.

Where to host a headless CMS?

The hosting options for a headless CMS depend on the type of CMS you choose. If you choose an open-source CMS like Strapi or Ghost, you will need to self-host it on a server, which can be a local setup or cloud-based on platforms like AWS, Azure, or Google Cloud. When you use a SaaS solution like Hygraph or Contentful, the vendor manages the hosting, so you can focus on content and development. Some platforms also offer managed hosting.

Should I use a headless CMS?

If you are creating a simple corporate website or portfolio, perhaps not. If you have development resources and are building multiple or complex websites, applications, and other digital products, then it may be worth exploring Headless CMS. The same applies to whether you require stronger flexibility and performance with your digital projects.

What means a cloud headless CMS?

A cloud headless CMS means a hosted solution where content is stored in the cloud and delivered via APIs. The vendor manages hosting, updates, and security, so teams can focus on creating and publishing content without maintaining infrastructure.

What’s the difference between headless vs. non headless CMS?

A headless CMS separates backend content from frontend presentation and delivers content via APIs to any channel. A non-headless (or traditional) CMS tightly couples content and design, which limits flexibility and reuse.

Are headless CMS the way to go?

Yes, headless CMSs are the way to go, especially for businesses that need omnichannel publishing, scalability, and future-proof flexibility. However, smaller projects with simple websites may still benefit from a traditional CMS.

What makes a headless CMS data-driven?

A headless CMS uses structured content models and APIs to store, query, and deliver data in consistent formats. This makes content machine-readable, reusable, and easily integrated with analytics, personalization, and AI tools.

How about a drag-and-drop headless CMS?

Some headless CMS systems offer drag-and-drop interfaces to make life easier for marketers. While useful for quick edits, these tools can limit scalability and consistency, so modular content components are still the more sustainable approach.

How do headless CMS platforms make content collaboration easier?

Headless CMS platforms make content collaboration easier by centralizing content in one hub, enabling roles and permissions, and supporting workflows for approvals. Editors work independently of developers, reducing bottlenecks and allowing teams to collaborate in parallel.
