Headless CMS

What is a headless CMS?

A headless CMS is a content management system that stores and organizes content but does not control how it looks. It serves everything through an API, leaving the presentation layer, the "head," entirely up to you. A traditional CMS like WordPress bundles the content and the website together. A headless one hands you raw content and lets your frontend decide what to do with it.

The term gained traction around 2015 as teams started shipping the same content to more than one place. A website, a mobile app, a smartwatch, a digital sign. With a headless approach, editors manage content once and any number of frontends pull from the same source over an API. This fits naturally with headless architecture and an API-first approach, where the backend is built to be consumed by anything. Contentful, Sanity, Strapi, and Storyblok are common choices. A retailer running a Next.js storefront and a native app that both read product copy from one Contentful space is a textbook case.

The trade-off is that you build the frontend yourself, so there is no theme to install and go. That cost buys flexibility. You are not boxed in by a CMS's assumptions about what a page is.

Headless CMS at Dallonses

We build with a headless CMS when content needs to live in more than one place or when the frontend has to be genuinely custom. Decoupling the two lets editors work in a clean interface while we build the experience in whatever stack the project demands. Our headless web development work tends to start by mapping the content model with the people who will actually maintain it.

An API-first approach changes how a project ages, too. When a client wants a new app or a redesign two years on, the content is already free of its old presentation, so we are not migrating it again. We have helped partners move off monolithic systems and onto headless setups they can grow into.

Content trapped inside one website? Let's set it free.
