What it does

GanttProject is a free, open-source desktop project-management application. Users can organize task hierarchies, define dependencies and milestones, establish baselines, view Gantt and PERT charts, assess resource loads, and calculate task costs.

The application exports projects to PDF, HTML, and PNG and supports interoperability with Microsoft Project, Excel, and other spreadsheet applications. Collaboration is documented through WebDAV and the commercial GanttProject Cloud service. The repository provides Gradle commands to build and run the application locally; the complete app can be built for Linux and macOS.
