GanttProject.org introduced GanttProject in 2003 as a free open-source Java-based tool for project scheduling. Users can access this free tool across Windows, macOS and Linux platforms where they can create Gantt charts and manage resources and track tasks while exporting to MS Project and PDF formats.
The latest version of GanttProject operates smoothly with timelines and milestones and dependencies while needing Java 17+ for operation in 2025. The lightweight project organizer receives more than 2,000 weekly downloads while remaining free for users. The basic design of this tool works well for small teams yet it does not provide cloud-based synchronization or contemporary visual appeal.
