Which Pega component is used for user interface design?

The Pega User Interface (UI) Designer is the primary component used for designing user interfaces within the Pega platform. This tool allows developers and designers to create visually appealing and functional interfaces for applications, facilitating user engagement and interaction.

With the UI Designer, users can leverage a variety of design elements such as layout templates, controls, and styling options to ensure that applications are user-friendly and meet business requirements. This component provides a range of visualization tools that enable rapid prototyping, iteration, and testing of interface designs, ultimately enhancing the overall user experience.

Other components mentioned, such as the Pega Process Modeler, are focused on modeling and automating business processes rather than designing user interfaces. The Pega Data Designer is concerned with managing and defining data structures, while the Pega Case Designer is tailored towards defining case types and the lifecycle of cases in an application. Each of these components plays a crucial role in the Pega ecosystem, but when it comes to user interface design specifically, the UI Designer is the most relevant choice.
