ProjectLibre is a free software project co-founded by Marc O´Brien that aims to compete with the Microsoft monopoly. ProjectLibre already has a new version of modular architecture called OSGI (Open Services Gateway Initiative), a project management software that aims to compete with Microsoft Project (MSP). In other words, it is a suite that offers companies the appropriate tools to manage projects, develop strategic plans, assign resources to tasks, track progress, manipulate budgets and analyze workloads.
ProjectLibre is created in Java, so it can run on various operating systems. It supports Microsoft Project and contains a multitude of project management tools (earned value management, Gantt chart, PERT charts, RBS, WBS, task usage reports, etc.). In the rest of the characteristics it is similar to MS Project.
During an interview, what he comes to say O'Brien, is that free software is maturing a lot in recent times, being considered an effective and interesting alternative to closed software. Marc himself points out that Microsoft became omnipresent in terms of office automation software, which is no longer the case with the arrival of opensource competitors such as OpenOffice and LibreOffice. O'Brien insists that there is still a long way to go, since Microsoft Project is present in 7% of desktop computers and represents revenue for the company of 1.000 million dollars.
