Balsamiq is a user interface design tool that allows designers and developers to create wireframes for websites and applications. It focuses on low-fidelity mockups, enabling users to sketch out ideas quickly without getting bogged down in details. This approach helps teams visualize concepts and gather feedback early in the design process. The software features a drag-and-drop interface, making it accessible for users of all skill levels. With a library of pre-made components, Balsamiq streamlines the design process, allowing for rapid prototyping. It is widely used in the tech industry to facilitate collaboration and improve user experience design.
