What is a Headless CMS?

A Headless CMS is a content management system without a built-in frontend (the 'head'). Content is delivered via API to a website, mobile app, or other channel. Rendering and design are entirely up to the developer.

How is it different from WordPress?

WordPress is monolithic – editing and display are tied in one system. A Headless CMS only stores and delivers content; the site is built separately (e.g. with Next.js) and fetches data via API.

What are popular Headless CMS platforms?

Contentful, Strapi (open source), Sanity, Prismic, Directus. Some are cloud services, others self-hosted. Strapi can be installed on your own server and fully customized.

When should I choose a Headless CMS?

When you want full control over the frontend, multi-channel content (web, mobile, IoT), a modern stack (React, Next.js), and better performance and security than a monolithic CMS.

Content editors don’t get WYSIWYG preview of the final site unless you add preview. It’s more complex than 'one WordPress' at first. It fits when you have a developer and clear requirements for UX and performance.

Headless CMS – What It Is and Why Use It for Web Projects

Headless CMS – What It Is and Why Use It

A Headless CMS separates content management from presentation. You can build the site or app with your preferred stack and serve multiple channels from one content source.

What does “headless” mean?

A traditional CMS has a “head” – the part that renders HTML and displays the site. A Headless CMS has no such head: it only stores structured content and exposes it via API (REST or GraphQL). Who displays the content and how is up to you – a Next.js site, mobile app, or even smart devices.

Benefits

Frontend freedom. You build the site with React, Vue, Next.js or whatever you prefer. No constraints from themes and plugins of a specific CMS.

Multi-channel content. One source of truth for copy, media, and structure – web, iOS, Android, feeds. Editors write once; content is consumed everywhere.

Performance and security. The site can be static (SSG) or heavily cached. The admin and public site are separate – smaller attack surface.

Modern editor experience. Many Headless CMS platforms offer comfortable editors, content versioning, and workflow – without worrying about core and plugin updates like with WordPress.

Popular platforms

Strapi – open source, can be self-hosted. Good for teams that want full control and integration with their own backend.

Contentful – cloud service, stable and scalable. Good for larger organizations and multi-channel content.

Sanity – flexible schema, real-time collaboration, portable editor. Good for more complex structures and content.

Directus – open source, can sit on top of an existing SQL database. Handy if you already have data and want an admin UI and API on top.

When to choose a Headless CMS

You want a modern web stack (Next.js, React) and full control over design and performance.
You need content for web and apps at the same time.
You want editors to work in a pleasant environment without maintaining themes and plugins of a monolithic CMS.
