Balsamiq

With a user friendly interface, Balsamiq makes it easy to create low fidelity wireframes. Even people with zero experience in wireframing could jump in and put together ones that look good. Balsamiq encompasses both UI and UX, but really stands out with its low fidelity wireframes. Balsamiq’s nod to the physicality of whiteboarding makes the tool accessible to anyone, no matter their skill level.
