Any open source alternatives to balsamiq mockup [closed]
Solution 1:
The best available Open source mock up tool is Pencil. Its available as firefox plugin as well as stand alone.
Another solution, which I personally use is Inkscape, an open source SVG Editor. It is NOT a mock up designer, but we can use it for designing mock ups, using freely available stencil kit, like Yahoo Stencil Kit.
Solution 2:
Mockingbird is free during beta
Firefox's pencil add-on is free forever
