GanttProject
Free, open-source desktop Gantt chart app for Windows, macOS and Linux
What is GanttProject?
GanttProject is an open-source project scheduling app for Windows, macOS and Linux desktops, aimed at small and medium businesses. It covers task scheduling with dependencies, a Gantt chart, resource allocation and cost calculation, and it reads Microsoft Project files. The app runs offline with data kept on the user's computer, and an optional paid service, GanttProject Cloud, adds team collaboration.
GanttProject has a free plan. Paid plans start at €1 per active team member / month for the optional Cloud service; desktop app is free. See every plan
