Headless Software refers to applications or systems that operate without a graphical user interface (GUI). These programs run in the background and are typically controlled via command-line interfaces, scripts, or APIs. In web development, headless software architectures decouple the backend from the frontend, allowing developers to build custom user interfaces while leveraging the backend's functionalities.

This approach offers greater flexibility, scalability, and the ability to deliver content across various platforms and devices, enhancing user experience and operational efficiency.
