Free project management app
Practical Gantt chart software for small and medium businesses.
Built for Small and Medium Businesses
GanttProject works best for businesses in construction, architecture, engineering, pharmaceutical, media production, and similar industries.
It is good for educational purposes as well, and it is free to use.
Local-First & Private
No cloud dependence, zero subscriptions. GanttProject runs offline on Windows, macOS, and Linux desktops. Your data stays entirely on your computer.
This said, we have a cloud service too.

Free Microsoft Project Alternative
for Windows, macOS and Linux.
GanttProject reads MPX, MPP and XML/MSPDI files produced by Microsoft Project, and exports to XML/MSPDI format, so exchanging files with those who use Microsoft Project is easy.
- Task scheduling
- Timeline visualization
- Resource allocation
- Cost management
without the steep learning curve. Running locally and offline across Windows, macOS, and Linux, it gets straight to work so you can start planning in minutes.
Trusted Worldwide Since 2003
Oh, and we do collaboration, too.
GanttProject is built offline-first. But what if you need to share schedules and co-edit with your colleagues?
Check out GanttProject Cloud. It’s a completely optional, zero-bloat cloud service that adds team collaboration to GanttProject — whenever you need it.
