I was looking for a GUI prototyping tool that I could use to draft a new skin for a website and also for an Android application. I knew of Balsamiq but I prefer not to use non-free software when possible. I found Pencil Project, an awesome open source prototyping tool built on top of Mozilla’s XUL runner.
The Pencil Project’s unique mission is to build a free and opensource tool for making diagrams and GUI prototyping that everyone can use.
It seems to be working just fine for my needs. Awesome!
Hello!
If you are seeking for a prototyping product, you can also evaluate:
– Balsamiq (http://balsamiq.com/products/mockups);
– Gliffy (http://www.gliffy.com/);
– MockFlow (http://www.mockflow.com/);
– Mockingbird (https://gomockingbird.com/).
I am almost searching the best (or better, the most useful) of them…but they are all interesting!
Hi Elena, Indeed they’re all interesting but none of them seems to be free as in freedom. Pencil seems to be good enough for my needs.
