Project HQ is an open source web based project management system. It is written in Python and is built on the Pylons framework. Project HQ's goal is to be an easy to use, well featured, open source project management application.
Project Management
Project HQ is based on other systems like Basecamp and activeCollab. By using input from people in the field, it hopes to deliver features and an interface that are both simple and powerful. Project HQ is written with software project management in mind, but could be adapted to other projects.
Open Source
Project HQ is open source software. This means that the source code (the programming instructions the developers write) is open to anyone who wants to look at it. This gives you, the end user, a few freedoms.
From a more developer orientated perspective, it gives you the freedom to inspect the code and make sure that it's not malicious, it gives you the freedom to change it, and it gives you the freedom to "fork" the project and make your own.
From an end user perspective, it gives you the freedom to use the software as you wish, it gives you the freedom to not pay for the software, and it gives you the freedom to make copies of the software and give it to anyone you want.
GNU General Public License
The GNU GPL was specifically chosen because it ensures the above-mentioned freedoms. It specifically states that you're not allowed to charge for the software, and that you have to distribute the source code as well.
