A headless CMS separates the content management "backend" — where content is created and stored — from the "frontend" that actually displays it to visitors. Instead of the CMS controlling how content looks, it simply delivers raw content (usually as JSON) through an API, leaving any frontend framework free to display it however it chooses.
Traditional CMS vs. Headless CMS
- Traditional CMS — content and presentation are tightly bundled together
- Headless CMS — content is decoupled entirely from how it's displayed
Why Anyone Chooses This Approach
- Total design freedom — any frontend framework can be used to display the content
- Content can be reused seamlessly across a website, a mobile app, and other platforms
- Often noticeably faster load times, since the frontend can be built for speed independently
- Greater flexibility for developers working with modern frontend frameworks
Headless WordPress as an Example
WordPress can itself be run headlessly, using its content management strengths purely as a backend while a separate framework like React or Next.js builds the actual frontend. It's a powerful setup, but a considerably more technical one — well suited to developers with specific performance or design requirements, and generally unnecessary for a typical small business site.
