## Key features

- **Gantt chart and task scheduling:** Tasks are arranged in a hierarchy with dependencies and milestones and drawn on a Gantt chart, with an option to generate a PERT chart.
- **Resource load chart:** Assign resources to tasks and see how much work each one carries on a separate resource load chart.
- **Baselines and cost calculation:** Save baselines to compare the current plan with an earlier one, and calculate the cost of tasks.
- **Microsoft Project interoperability:** Reads MPX, MPP and XML/MSPDI files produced by Microsoft Project and exports to XML/MSPDI, so plans can be exchanged with Microsoft Project users.
- **Export to PDF, HTML and PNG:** Plans can be exported as PDF, HTML or PNG, and exchanged with Excel and other spreadsheet apps.
- **Optional team collaboration:** Projects can be shared over WebDAV, or through GanttProject Cloud, which adds team access management, project locks, update notifications and a history of recent changes.

## Good for

- Small and medium businesses that want Gantt charts at no cost
- Exchanging schedules with people who use Microsoft Project
- Planning offline on Windows, macOS or Linux

## Worth knowing

- Sharing a project with a team needs WebDAV or GanttProject Cloud, which is billed in euros from prepaid credits with a EUR 10 minimum top-up.
- The vendor says it is not designed to replicate every high-end enterprise feature of Microsoft Project.
- The current stable release, 3.3, came out in January 2024 and was last updated in January 2025; version 3.4 is in beta.
