What is a headless CMS and do I need one? — answered by Engineer Saeed Baatiah
A content management system that stores content and serves it through an API without dictating how the site looks. Its benefit is that the same content serves the website, the app, and any other channel without duplication. You need one if you have more than one surface showing the same content, or want full design freedom while keeping editing easy for a non-technical team. For a single simple site, it is added complexity with no clear return.
