What is Balsamiq?

Balsamiq is a rapid wireframing tool that helps designers, developers, and product managers quickly prototype user interfaces for websites and desktop/mobile applications. It uses a low-fidelity, hand-drawn style to encourage collaboration and focus on functionality and content rather than visual design details early in the design process. It is commonly used to brainstorm ideas, visualize user flows, and gather feedback on usability before committing to detailed designs.
