The phrase "GanttProject free download" tends to come from someone tasked with scheduling a project who needs Gantt charts today, not a monthly software bill. This guide covers the official installer for Windows, macOS, and Linux, and explains how its file-based project format compares to cloud project tools.
File-Based, Not Cloud-Based Planning
GanttProject saves projects as local files rather than storing them in the cloud, meaning no account signup and no recurring fee, but also no built-in real-time collaboration.
It exports to PDF, image, and MS Project XML formats, so plans can still be shared with teams on paid tools.
Who ends up using GanttProject
Small teams and solo project managers who need a real Gantt chart but don't want a Microsoft Project subscription tend to pick GanttProject.
- Freelance project managers scheduling client deliverables on a clear visual timeline
- Small teams planning construction, event, or software milestones without cloud tool costs
- Students learning project scheduling concepts for coursework or certification prep
Before you install
A couple of things worth knowing about GanttProject before you request the link: it covers Windows, macOS and Linux, so pick the right build for the machine you're setting up. And on pricing, GanttProject is open source, so the installer is free with no trial timer, feature lock, or upsell screen to click past. It's developed and maintained by GanttProject Team.
System requirements
- WindowsWindows 10 or 11 (64-bit); older 7/8.1 builds usually still run but no longer get official support
- macOSa recent macOS release — check the download page for the current minimum version, since Apple Silicon vs Intel builds sometimes differ
- Linuxmost current 64-bit distributions; look for a native .deb/.rpm/AppImage or a package in your distro's own repository
It's a lightweight tool, so there's no serious CPU/RAM/storage requirement beyond what its OS already needs to run comfortably.
Quick steps
- Download the version matching your operating system below
- Install and open the sample project to see the Gantt layout
- Save your project file locally or on a shared drive for teammates
GanttProject: the honest trade-offs
- Full Gantt chart and resource-loading features come with no subscription cost
- Exports to MS Project XML, PDF, and image formats for sharing
- Works entirely offline from local project files with no account needed
- No built-in real-time collaboration, so simultaneous multi-user editing isn't supported
- Interface feels more utilitarian than modern cloud-based planning tools

Keeping GanttProject up to date
Since GanttProject is open source, most Linux distributions keep it current through their own package manager. On Windows/macOS, re-running the installer from the official site (or an updater built into the app, if it has one) gets you the latest release. Sticking to the developer's own distribution channel — which is what this page links to — means you're never stuck on an old build with unpatched bugs just because a mirror site stopped updating its copy.
Features, install steps, alternatives and more detail live on the main GanttProject page.
Frequently asked questions
Can multiple people edit a GanttProject file at once?
Not natively; it's a single-file format best shared via a common drive or version control rather than live co-editing.
Does it work without installing Java separately?
Recent GanttProject releases bundle their own Java runtime, so a separate Java install usually isn't required.
