Introduction

The way we create and deliver content has changed fundamentally. While traditional CMS systems such as WordPress content and presentation are closely linked, a Headless CMS completely separates these two aspects. The result: maximum flexibility for omnichannel strategies.

What is a Headless CMS?

A headless CMS is a content management system that provides only the "backend" – the management and storage of content. Delivery to the end user is done exclusively via APIs. There is no predefined frontend ("Head"), therefore the name "Headless".

Headless CMS are the heart of JAMstack architecture (JavaScript, APIs, Markup). Static site generators such as Next.js, Gatsby or Astro refer content to build time via the content API and generate flash-fast, secure websites.

E-commerce
