What is Headless CMS?!

From Wikipedia:

"A headless content management system, or headless CMS, is a back-end only content management system (CMS) built from the ground up as a content repository that makes content accessible via a RESTful API for display on any device.

The term “headless” comes from the concept of chopping the “head” (the front end, i.e. the website) off the “body” (the back end, i.e. the content repository)."

Cloud-first (On-prem bleeee)
Content-first
Omni-channel
Content Delivery

Data-driven approach

• No references to "how" it will be rendered
• Simple data types
• Small document types
• Document != page

Display-driven approach

• "Preview" of the data representation
• Complex data types (to simplify content editing)
• Inline editing
• Document == Page

It depends.
