As user interface (UI) design has become an increasingly critical component of product development, the need for efficient prototyping tools has grown. Prototyping allows designers to quickly experiment with design ideas, gather user feedback, and iterate on the UI before investing significant time and resources into full implementation.

Some of the top UI prototyping tools used by designers today include

1. Figma:

   https://www.figma.com

   One of the best tool for designers and Teams. Figma is a powerful design and prototyping tool that allows designers to create high-fidelity interactive prototypes.
   Figma is also developing new features every year by listening to its community, making it really attractive to designer who want to make their workflow faster.
