What does the term 'headless' refer to in the context of Sitecore development?

The term 'headless' in the context of Sitecore development refers to a model where the front-end is decoupled from the back-end. This architecture allows developers to create a flexible front-end experience while utilizing Sitecore’s powerful back-end capabilities efficiently. In a headless setup, content management and presentation layers operate independently, enabling content to be delivered through various channels, such as web, mobile apps, or even IoT devices, using APIs.

This approach benefits teams that want to use modern front-end technologies or frameworks while still leveraging Sitecore for content management and delivery. It promotes a more agile development process, allowing front-end and back-end developers to work concurrently on their respective tasks without being constrained by one another's timelines or technologies. Thus, 'headless' signifies a shift towards more modular, service-oriented applications in the Sitecore ecosystem.
