Balsamiq
Low-fidelity wireframing tool for founders, PMs, developers, students, and senior UX professionals. :) We make work fun!Balsamiq is a solid, independent little software company. We believe that life’s too short for bad software! We started in 2008 as a one-man-shop, and have been growing organically ever since. Balsamiq Wireframes is our small graphical tool to sketch out user interfaces, for websites and web / desktop / mobile applications. We focus on the ideation phase, providing you with a clean tool that lets you get in the flow and stay focussed on structure rather than colors and icons.
