A UI prototype is a simplified, interactive representation of a user interface, created to visualize and test the design of a digital product. It focuses on key functionalities, layout, and navigation flow without the full backend or final visual details. Prototypes can range from low-fidelity sketches to high-fidelity digital models with clickable elements. They help designers gather feedback, refine ideas, and ensure the interface meets user needs before development. Prototyping tools like Figma, Adobe XD, or Sketch are commonly used for this purpose.
