OpenProj is an open source project intended as a complete desktop replacement for Microsoft Project; it can open existing native Project or Primavera files. OpenProj runs on the Java Platform, allowing it to run on a variety of different operating systems including Linux, Unix, Mac or Windows.
OpenProj shares the industry’s most advanced scheduling engine with Project-ON-Demand and provides Gantt Charts, Network Diagrams (PERT Charts), WBS and RBS charts.
OpenProj and Project-ON-Demand share the same scheduling engine and many core project management features. The primary differences between Project-ON-Demand and OpenProj are the delivery model and several additional server-side features in Project-ON-Demand. Project-ON-Demand is a hosted SaaS solution delivered on a monthly subscription.
The OpenProj solution has been translated into French, Spanish, German, Portuguese, Swedish, Finnish, Galician, Persian, Russian, Korean and Chinese.
