ProjectLibre is an open source alternative to Microsoft Project. It is compatible with Project 2003, 2007 and 2010 files and runs on Linux, Mac or Wiindows. ProjectLibre is perfect as a compliment to OpenOffice and LibreOffice. Microsoft Project is on 7% of all desktops so this is a significant addition to the open source ecosystem.
ProjectLibre was named open source "Project of the Month" on sourceforge and has received good press coverage. The ProjectLibre solution has been downloaded in 182 countries and is being actively used in all EU countries.
There is a robust community at http://www.projectlibre.org which you can join and also download ProjectLibre. There are currently aproximately 12,000 downloads a week.
The ProjectLibre team has the most domain expertise in the industry with innovations dating back to the mainframe, VAX, DOS and Windows era. The team released the very first web-based project management application.
We are continuing to develop ProjectLibre on the desktop and also a Server/Cloud solution.
Our development budget is in excess of €1M yearly.
