Headless solutions separate the frontend presentation layer of an application from its backend functionality. In simpler terms, the user interface of the software is separated from the logic and data storage behind it. This allows developers to create user interfaces that are decoupled from the backend, which makes the application easier to scale and maintain—meaning developers can use any frontend technology they prefer without being restricted to a specific backend. Headless solutions store content and product data in a backend database or API, while the frontend is responsible for displaying that information to the user.
