A headless CMS is a content management system which stores content and delivers the content through an API, without deciding how a website looks. First, editors manage texts and images in one place. Second, developers show the same content on a website, an app or a screen, for example with Next.js. Well-known options in 2026 are Strapi, Sanity, Payload and Directus. WordPress can also run headless through the REST API, and WordPress powers 39.7% of all websites according to W3Techs. Finally, budget matters: a business website from VirtuoLab has an indication of €2,000 to €8,000. A headless setup adds work for the content model and the previews, so a small site with 5 pages often needs no CMS at all. The sections below explain the benefits, the drawbacks, the costs and the five main options.
What is a headless CMS?
A headless CMS is a content management system without a built-in front end, the head which turns content into web pages. The CMS stores content as structured data, such as a blog post with a title, a summary, an author and a body. First, developers define the content types and fields in a content model. Second, editors fill in the fields in an admin interface, without touching code. Finally, the CMS delivers the content as JSON through an API, usually REST or GraphQL, as offered by Strapi. A website built with Next.js, a mobile app or a digital screen then renders the same content in its own way. For example, one product text can feed a website, an app and a screen, so editors update 1 text instead of 3. In practice, a headless CMS separates two jobs in 2026: editors own the content, and developers own the presentation. A decoupled CMS, a related term, usually adds an optional front end next to the API.
How is a headless CMS different from WordPress?
A traditional CMS such as WordPress is a single system which stores content, applies a theme and renders the final HTML pages. Editors see the result almost directly, and plugins add features to both the admin panel and the website. A headless CMS stops at the content: the website is a separate application, often built with React or Next.js. The difference shows up in daily work. In practice, changing the layout of a WordPress page usually means changing the theme or a page builder. With a headless CMS, editors change content and developers change templates in code. WordPress can also run headless. According to the WordPress REST API handbook, the API can bring WordPress content into completely separate applications, so a team keeps the familiar dashboard while Next.js renders the site. Additionally, WordPress runs 39.7% of all websites, according to W3Techs in October 2026. Many editors therefore already know the WordPress dashboard well.
What are the benefits of a headless CMS?
The main benefit of a headless CMS is freedom: the content stays the same while the front end can change. First, developers choose the front-end technology, such as a website with Next.js and a mobile app with React Native. React, the library underneath both, was used by 44.7% of respondents in the Stack Overflow Developer Survey 2025. Second, one source of content can feed several channels. The Content Lake stores content as structured data, ready for delivery to any channel, according to Sanity. Third, performance improves when pages are prerendered. The Next.js documentation describes Incremental Static Regeneration as a way to update static content without rebuilding the entire site. Fourth, security improves, because the admin interface does not run on the public website. Additionally, a redesign becomes cheaper later, because content does not have to be migrated again. For example, a company with a website in 3 languages and a customer app can manage every product text once, in one CMS.
What are the drawbacks of a headless CMS?
The biggest drawback of a headless CMS is extra complexity: two systems instead of one, each with hosting, updates and access control. First, previews need work. Editors expect to see a page before publishing, and a separate front end only shows drafts when the developer builds a preview route. Next.js solves the preview problem with Draft Mode, which lets editors see draft content while other visitors keep the cached page. Second, a headless CMS has no theme marketplace or drag-and-drop page builder by default, so layout changes need a developer. Third, the first build costs more than a WordPress site with a ready-made theme. Finally, hosted CMS services come with a subscription, which can grow with users or usage. In practice, a headless CMS pays off for content-heavy sites, several channels or strict performance targets in 2026. A small business site with 5 pages often works fine without any CMS at all.
Which headless CMS should you choose in 2026?
The best headless CMS is the option which fits the existing stack, the hosting preference and the editors. Five options cover most projects in 2026. First, Strapi is an open-source headless CMS on Node.js, running on an own server or on Strapi Cloud, with MySQL, MariaDB, PostgreSQL or SQLite as database. Second, Sanity combines an open-source, real-time collaborative Studio with the Sanity Content Lake and the GROQ query language. Third, Payload is the Next.js fullstack framework according to Payload's own documentation, and Payload installs into a new or existing Next.js app with MongoDB or Postgres. Fourth, Directus connects to an existing database and provides a REST and GraphQL API on top, under the Monospace Sustainable Core License. Finally, headless WordPress suits teams already working in WordPress. For example, a marketing site with 20 pages in one Next.js codebase points to Payload, while a team with an existing SQL database points to Directus.
How does a headless CMS work with Next.js?
The connection between Next.js and a headless CMS is a four-step flow: model, fetch, refresh and preview. Step 1 is the content model, for example pages, blog posts and FAQ items with fixed fields. Step 2 is fetching: Server Components request the content from the CMS API and render HTML on the server or at build time. Step 3 is refreshing. Pages can revalidate after a set time, or on demand with revalidatePath or revalidateTag after a webhook from the CMS, according to Vercel's Next.js documentation. A site with 300 pages then rebuilds only the page which changed. Finally, step 4 is previewing with Draft Mode: the CMS opens a secret preview URL, and Next.js checks the secret, sets a cookie and shows the draft. VirtuoLab is a software agency in Papendrecht that builds websites with Next.js and connects content sources through APIs. A business website has an indication of €2,000 to €8,000 in 2026, with a fixed price after a free introductory call.
Frequently asked questions
Is WordPress a headless CMS?
WordPress is a traditional CMS by default, because WordPress stores content and also renders the pages with a theme. WordPress can work as a headless CMS through the built-in REST API. Any programming language which can make HTTP requests and interpret JSON can use the API, according to WordPress documentation. In a headless setup, editors keep the WordPress dashboard and Next.js builds the public website. The setup has trade-offs. First, plugins which change the front end, such as page builders, no longer affect the website. Second, two systems need hosting and updates. Finally, the preview button needs a custom preview route. In practice, headless WordPress makes sense when a team already publishes in WordPress, for example a news site with 200 pages, and wants a faster front end in 2026. A new project without WordPress habits often fits better with Sanity, Strapi or Payload, systems designed as headless from the start.
What does a website with a headless CMS cost?
The cost of a website with a headless CMS is the build of the front end plus the setup of the CMS, the content model and the preview. At VirtuoLab, a business website has an indication of €2,000 to €8,000 and a webshop €5,000 to €20,000 in 2026. First, a headless setup adds work for the content model, the preview route and cache refreshes, so the scope decides where a project lands within the ranges. Second, running costs come on top: hosting for the website, plus either hosting for a self-hosted CMS such as Strapi or a subscription for a service hosted by Sanity. Open-source options such as Payload and Strapi have no license fee for the core software. For example, a site with 10 pages and a blog needs a much smaller content model than a multilingual catalogue with 500 products. The exact price follows after a free introductory call.
Can editors still preview pages with a headless CMS?
Yes, and a preview is a standard part of any good headless setup. In Next.js, the preview feature is called Draft Mode. Draft Mode lets editors see how draft content will render without waiting for revalidation, according to Vercel's documentation. Any headless CMS which can open a custom preview URL, such as Sanity, Strapi or Payload, works with Draft Mode. The flow has three parts. First, the CMS opens a preview URL with a shared secret and the path of the page. Second, a Route Handler in Next.js checks the secret, enables Draft Mode by setting a cookie and redirects to the page. Third, Next.js skips the cache for the editor and fetches the latest draft from the CMS, while other visitors keep seeing the published version. In practice, editors trust what appears on screen, so preview setup is an essential part of every headless project in 2026. Additionally, a preview banner with an exit button shows editors which mode is active.
