About This Constellation ShortList™

A headless CMS is a content aggregation, storage, and management solution that is fully disconnected from any specific presentation layer. Instead, via an API, a headless CMS connects content from a back-end system to pull content into any number of front-end delivery layers. This enables content—along with the workflows, processes, and controls associated with that asset—to be created regardless of programming, development, or the environment language of the end delivery platform or device.

This separation serves several important purposes, chief among them freeing content creators from the confines of delivery destination limitations while also freeing front- end presentation developers from the inefficiency of developing for single-use applications. Because front-end and back-end systems are separated, developers, creators, and builders can update any underlying system as needed and independently of one another. Headless CMS depends on developer resources, so marketing teams should take note that there is no WYSIWYG editor in a headless CMS.

There is a broad market for content management solutions, ranging from traditional website-based systems to decoupled or hybrid solutions and enterprise-wide content solutions. This ShortList narrows the view to headless solutions. The other types of solutions are not inferior to headless solutions...but they are different, and Constellation Research assesses them separately.
