What is a prototype in UX?

A prototype in UX is an early, simplified version of a product or interface created to test ideas, concepts, and user interaction with the system. Prototypes help visualize and test the design before development begins, identify issues, and gather feedback.

There are different types of prototypes:

• Low-fidelity — simple sketches or wireframes, often without interactivity.
• High-fidelity — interactive mockups that closely resemble the final product.

For example, a mobile app prototype might include several screens with navigation to test usability and logic.

Using prototypes saves time and resources, improves user experience, and aligns the team and client’s vision.
