What is GanttTool?

GanttTool is an advanced yet completely free project management solution that helps users build polished Gantt charts using PlantUML without signups, limits, or watermarks. It runs entirely within the browser, relying on LocalStorage to auto-save progress so all project data remains private and never leaves the user’s device. The tool includes an intuitive interface for creating tasks, milestones, phases, and dependencies with real-time validation to detect cycles and scheduling conflicts. Its powerful timeline engine allows flexible planning through absolute dates, relative offsets, or chained task dependencies. Users can customize chart appearance by adjusting colors, fonts, and styles, making it useful for reports, presentations, and documentation workflows. GanttTool also supports resource allocation indicators, task notes, and hyperlink attachments to keep project context organized. Projects can be exported as high-quality SVG graphics, copied as PNG images, or downloaded as PlantUML code for further editing or automation. JSON import/export capabilities allow users to manage multiple project files effortlessly. The drag-and-drop system enables rapid task reordering, while non-working day logic enhances schedule accuracy. Altogether, GanttTool offers a surprisingly feature-rich Gantt chart experience that rivals paid tools while remaining free forever.
