Top 8 UI prototyping tools to try in 2023

Discover the list of the UI prototyping tools available on the market. Find out their features and cons, and make an informed decision when building prototypes.

What is UI prototyping?

User Interface (UI) prototyping is an essential step in the design process, allowing designers and developers to create a visual representation of a user interface before it is fully developed. With the help of UI prototyping tools, designers can create a prototype, test its usability, and gather feedback from users, ensuring that the final product meets user expectations and provides a smooth user experience.
