ProjectLibre
ProjectLibre, available for Desktop and Cloud, is an enterprise project management platform that combines professional scheduling, portfolio management, collaboration, risk analysis, and AI-assisted planning. The cloud platform can import Microsoft Project files, including .MPP and .XML schedules, so organizations can continue working without rebuilding existing project plans. Its scheduling capabilities include Gantt charts, critical path analysis, dependencies, calendars, baselines, milestones, resource leveling, and EVM. ProjectLibre AI can create work breakdown structures, tasks, dependencies, resources, durations, and milestones from natural-language project descriptions.
ProjectLibre Desktop is the #1 open-source alternative to Microsoft Project — 8.7M+ downloads, 193+ countries, translated into 31 languages, used at 1,700+ universities.
ProjectLibre Cloud is our SaaS / AI team platform and a strong replacement path as Microsoft Project Online retires Sept 30, 2026.

LibreCAD
LibreCAD is a free Open Source CAD application for Windows, Apple and Linux. Support and documentation are free from our large, dedicated community of users, contributors and developers. LibreCAD started as a project to build CAM capabilities into the community version of QCad for use with a Mechmate CNC router. Since QCad CE was built around the outdated Qt3 library, it had to be ported to Qt4 before additional enhancements. This gave rise to CADuntu. The project was known as CADuntu only for a couple of months before the community decided that the name was inappropriate. After some discussion within the community and research on existing names, CADuntu was renamed to LibreCAD. Porting the rendering engine to Qt4 proved to be a large task, so LibreCAD initially still depended on the Qt3 support library. The Qt4 porting was completed eventually during the development of 2.0.0 series, thanks to our master developer Rallaz, and LibreCAD has become Qt3 free except in the 1.0.0 series.

Libreplan
With LibrePlan you identify the tasks which make up a project and estimate the hours needed to accomplish them. You do it by creating hierarchical structures (WBS) with containers and leafs in a graphical and powerful way. LibrePlan gives you the flexibility to choose the level of the WBS tree at which you create Gantt tasks. You can do coarse or fine-grained planning. Once created the planning tasks you are provided with an interactive interface to create the Gantt chart. Collaborative planning is enforced by allowing to involve actively the workers in the projects by binding them to a type of LibrePlan users, called bound resources. A bound resource is a special worker linked to a user. Workers are the resources planned in the projects and, by becoming bound resources with users associated to them, they can help in the project planning by tracking data.
