Our verdict on GanttProject
GanttProject is a free, open-source desktop project management application for small and medium-sized businesses. It suits teams in construction, architecture, engineering, pharmaceutical, and media production that need structured project schedules without a subscription-based core application. The software runs locally on Windows, macOS, and Linux, and its GPLv3 license supports an open-source distribution model. Its focus is project planning rather than broad, browser-based work management.
Its strongest area is schedule depth. Users can organize tasks into hierarchies, connect dependencies, define milestones and baselines, and generate Gantt charts for timeline planning. PERT chart generation adds another planning view, while resource load charts and task cost calculations extend the application beyond basic date tracking. These features make it suitable for planners who need to model project structure, resource demands, and costs in one desktop workflow. Export to PDF, HTML, and PNG also supports sharing project information with people who do not work in the application.
Platform and ecosystem fit are more focused. GanttProject supports interoperability with Microsoft Project and spreadsheets, including Excel, and offers project collaboration through WebDAV and GanttProject Cloud. Those options provide paths for exchanging schedules and collaborating, but the core product remains a local desktop application, and GanttProject Cloud is a separate optional service. Choose GanttProject when free Gantt scheduling, offline use, open-source licensing, and detailed planning features matter most. Teams seeking a broader collaboration environment or a wider integration surface should consider a product built around those needs instead.
