Many years ago, I wrote a very simple project management system that did PERT and Gantt charts on Windows 3.1. It was mostly an exercise for me to learn object-oriented programming on Windows, so I just did the basics, nothing fancy. I've noticed that most project management software is either way too complicated or so superficial as to be nearly useless. (Ok, my efforts were definitely in the latter category.)

So a lot of folks I know use Microsoft Project, but few of them seem to be in love with it.So I was interested to learn about an open source alternative called OpenProj from Projity. They offer the software as a desktop version and also as a hosted on-demand version. The software is still beta, and Java source is available on sourceforge. It’s published under the CPAL open source license and runs on Windows, Linux and Mac and is supposed to open existing Microsoft Project files. I haven’t tested it yet, but if others have feedback, please post comments here. Open Source
