What Is a headless CMS? Definition & Guide

A headless CMS is a content management system with no presentation layer ("head"): it stores content and delivers it through APIs to any site, app or device.

The difference from a traditional CMS

In a traditional CMS like WordPress, content and presentation are tied together. In a headless CMS the "head" — the front-end that renders pages — is detached: the CMS only manages the data and delivers it through an API. The site or app that displays it is built separately.

Benefits of the headless approach

• Multi-channel: the same content feeds a website, a mobile app and other channels.
• Performance: the front-end can use modern, fast technology with a framework of your choice.
• Security: separating the layers reduces the attack surface.

When it makes sense

Headless is worthwhile when you publish the same content across several platforms or want maximum technical freedom on the front-end. For a simple brochure site it is often overkill. If you're unsure which approach fits, our web development service weighs the costs and benefits with you.
