GanttProject review

GanttProject is desktop software for planning project schedules, resources, costs and timelines. Its main view is a Gantt chart: tasks are laid out on a timeline so teams can plan and track a project’s schedule. The app runs offline on Windows, macOS and Linux, and project data stays on the computer when using the desktop version.

The feature list covers task scheduling, resource allocation and cost management. GanttProject also reads Microsoft Project MPX, MPP and XML/MSPDI files, and exports to XML/MSPDI. That makes it a potential fit for teams exchanging schedules with Microsoft Project users, though the published details do not say how complete file compatibility is.

The desktop app is free, according to the published pricing information. GanttProject Cloud is an optional service for sharing schedules and co-editing with colleagues. Its price is not published, so the free desktop download should not be confused with free team collaboration.

The clearest reason to consider GanttProject is straightforward: the desktop app combines scheduling, resource allocation and cost management without a listed software charge. It works offline on Windows, macOS and Linux, which suits teams that want to keep project data on their own computers rather than depend on a cloud workspace.

• No desktop subscription price: The pricing information lists GanttProject desktop at $0, with task scheduling, resource allocation and cost management included.
• Offline use: The desktop version runs locally, so an internet connection is not required for its listed planning work.
• Microsoft Project file support: It reads MPX, MPP and XML/MSPDI files, and exports to XML/MSPDI. That gives teams specified file formats for moving schedules between tools.
• Optional collaboration: Teams can use GanttProject Cloud to share schedules and co-edit with colleagues. The pricing information says there are no monthly subscriptions and no credit card is required.

That puts GanttProject in a different lane from per-seat project platforms. In one Reddit thread about alternatives to GanttPRO, a commenter pointed people looking only for a timeline toward free GanttProject. That is a user’s comparison, not evidence that it replaces a broader project-management suite.

The main drawback is the gap between the free desktop app and the collaboration option. The pricing information describes Cloud as pay-as-you-go, but does not publish a price, usage rate, or other billing details. There is no monthly subscription, according to that information, but teams cannot calculate a collaboration bill from the published published details.

The feature list is focused on schedules, resources, costs and timelines. It does not specify other project-management functions, so teams should not assume they are included. Cloud is described as the route for sharing and co-editing; the published details do not say whether those functions are available in the offline desktop app.

File support has limits worth checking before switching: GanttProject reads MPX, MPP and XML/MSPDI, but the details do not establish how much data transfers intact. Export is listed for XML/MSPDI, not every format it can read. No user, project, task or storage caps are published in the published pricing information, so we cannot confirm whether Cloud imposes them. The desktop version is the clearer low-cost choice; collaboration costs and limits remain uncertain.

GanttProject’s desktop app is free, according to the published pricing details. It runs offline on Windows, macOS, and Linux and includes task scheduling, resource allocation, and cost management. There is no paid desktop tier or listed add-on to price in.

The cost change comes if your team needs collaboration. GanttProject Cloud supports sharing schedules and co-editing, but its price is not published; the service is pay-as-you-go, with no monthly subscriptions. The pricing details also say no credit card is required. That makes the desktop-to-cloud jump hard to budget: there’s no listed rate to compare with the free app.

Annual billing is not listed, and no add-ons or trial terms are provided. So the desktop price is clear, but cloud costs are not. If you need a confirmed collaboration budget before switching, ask GanttProject for current rates rather than assuming the cloud service will remain free.

GanttProject reads Microsoft Project MPX, MPP, and XML/MSPDI files, and exports to XML/MSPDI, according to the published product details. That gives teams using those formats a documented route for bringing schedules in or taking them elsewhere. The sources do not specify how much cleanup an imported project may need, or whether every detail transfers, so check a representative file before moving a full portfolio.

The desktop app runs offline and keeps project data on your computer. Teams that need to share schedules or co-edit have the optional Cloud service; its price is not published. Moving away may mean exporting to XML/MSPDI, but the published details do not describe a broader migration tool or list other export formats.

We can’t attribute reasons for leaving to Reddit: no Reddit posts or comments were included in the published material. The clear decision point here is whether the free offline workflow and documented file formats fit your team, or whether you need collaboration costs and support terms published upfront.
