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.
Simple & Focused
No enterprise bloatware. Get straight to work with a practical, clutter-free tool. Start planning your first project in minutes — no MBA required.
Free Microsoft Project Alternative
- 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.
- While GanttProject isn't designed to replicate every high-end enterprise feature of MS Project, it delivers all the core capabilities small and medium businesses need — like task scheduling, timeline visualization, and resource allocation — 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.
