ProjectLibre is a project management software company with both a free open-source desktop and an upcoming Cloud version. The desktop is a free and open-source project management software system intended ultimately as a standalone replacement for Microsoft Project.
ProjectLibre is written in the Java programming language, and will thus theoretically run on any machine for which a fully functioning Java virtual machine (JVM) exists. Currently, ProjectLibre is certified to run on Linux, MacOS, and Microsoft Windows.
