Headless, generally speaking, refers to systems that separate the frontend from the backend. The frontend includes the user interface and thus everything you can see on a web page, for example. In contrast, the backend encompasses everything you can’t see and takes place in the background of a web page or, more commonly, a web application. By decoupling these two areas, the system architecture of a headless system is not rigid, but open and offers companies the opportunity to flexibly connect data sources and applications via API interfaces. In the next sections, we will explain the advantages this brings with regard to product content management and the online presence of a business.
