GanttProject is a free, open-source desktop application for project scheduling, built around the Gantt chart view used to plan tasks, milestones and dependencies over time. It also includes resource management, so you can assign people to tasks and see workload, plus a PERT chart view for dependency analysis. It can import and export Microsoft Project files, which makes it a practical free alternative for small teams and individual project managers.
GanttProject vs Microsoft Project
Microsoft Project is a paid, subscription-based tool aimed at enterprise project management, while GanttProject offers the core scheduling workflow — Gantt charts, dependencies, milestones and resource loading — completely free as a desktop application. Its Microsoft Project file compatibility lets teams exchange schedules with organizations that still use MS Project.
