Headless CMS explains: Why WordPress has spent (sometimes)

Short: WordPress still runs 40% of the web.

WordPress still runs 40% of the web. But for modern, scalable applications, the "monolith" is often too difficult. The solution: Headless CMS.

Imagine you could manage your content in one place and send it to your website, app, smartwatch and refrigerator at the same time.

This is the promise of Headless.

What does "Headless" mean?

A classic CMS (such as WordPress) has a "head" (the frontend, i.e. the theme) and a "body" (the backend/database) that are permanently growing.

A Headless CMS has no head. It is only the body (database + admin panel). The content is provided via a API (interface).

As a developer, you build your head yourself – with React, Vue, Svelte or whatever you want.
