Axure vs Balsamiq Mockups
Create Prototypes of Websites & Apps Without Coding. Axure RP gives you the wireframing, prototyping and specification tools needed to make informed design choices, persuade any skeptics, get your design built to spec... and maybe win a few fans along the way. Choose the Standard edition for prototyping or go Pro to add documentation and collaboration features.
Mockups really shines during the early stages of designing a new interface. Mockups offers the same speed and rough feel as sketching with pencil, with the advantage of the digital medium: drag & drop to resize and rearrange elements, make changes without starting over, and your work is clear enough that you'll make sense of them later.
