Openproj – Open Source Project Management Solution
http://www.openproj.org/

OpenProj is a free, open source project management solution. OpenProj is a complete replacement of Microsoft Project and other commercial project solutions. A free download of OpenProj is available here. OpenProj is ideal for desktop project management and is available on Linux, Unix, Mac or Windows. It even opens existing Microsoft or Primavera files. OpenProj shares the industry’s most advanced scheduling engine with Project-ON-Demand and has Gantt Charts, Network Diagrams (PERT Charts), WBS and RBS charts, Earned Value costing and more. There is literally no time or effort involved in switching to OpenProj, and your teams can manage projects on any platform for free. Projity worked closely with leaders in the commercial and open source industries in preparation for the release of OpenProj. It is a welcome addition, not only for project management users, but also for users in all software segments.
