Download GanttProject – Free Open Source Gantt Chart Project Management Tool

GanttProject is a free, open-source project management application that specializes in Gantt chart creation and management. It provides an intuitive visual timeline interface for planning projects, scheduling tasks, assigning resources, and tracking dependencies — all without the cost of commercial project management software like Microsoft Project.

Built in Java, GanttProject runs on Windows, Linux, and macOS and is suitable for project managers, team leads, and students who need to plan and visualize project schedules. Tasks can be organized hierarchically, linked with dependencies, and assigned to team members from a built-in resource pool, with workload charts showing resource utilization over time.

GanttProject supports importing and exporting to Microsoft Project (.mpp) format, and can export charts to PDF, PNG, and CSV for sharing with stakeholders who don’t have the software. It also integrates with Google Project for cloud collaboration.
