Understanding Contentstack
Contentstack is a CMS backend for your digital properties
Contentstack is a content management system, but a headless one. It provides the infrastructure to create and manage content, but it is not coupled to any single presentation layer, such as websites (which is commonly the case with today’s CMSs).
It is headless, which means it can serve content in a presentation-independent way. It provides REST APIs to deliver content to any channel such as websites, mobile apps, devices, marketing kiosks or any digital platform that displays content.
