Watch Simen Svale, CTO and Founder at Sanity, providing a precise explanation of a Headless CMS, using a gnarly metaphor. What is a Headless CMS? A headless CMS is a content management system that provides a way to author content, but instead of web page rendering, it provides the content as data over an API. A headless CMS works by giving editors an interface for managing content while providing APIs for developers to build applications on top off. Most headless CMSes are offered as a Software as a Service, meaning that your editors will have to log into a web application and that the APIs are hosted in a cloud-based backend. Some headless CMSes will let you host the whole solution on your own server and database (requiring you to do your own scaling and operations). With Sanity you can host the customizable editor interface yourself while getting the advantages of the hosted real-time backend – no-ops and effortless scaling.
