A Headless Content Management System (CMS) is a backend-only platform that manages content without a predefined frontend or presentation layer. Content is stored and delivered via APIs, enabling developers to present it across various channels and devices using different technologies. This approach provides flexibility in design and user experience, allowing for seamless integration with other systems and facilitating omnichannel content delivery.

Headless CMSs are particularly beneficial for organizations aiming to deliver consistent content across multiple platforms while maintaining centralized control over content management.
