What is ProjectLibre?

ProjectLibre provides desktop and cloud project management software for advanced scheduling, portfolio coordination, resource planning, risk analysis, and team collaboration. Organizations can import existing Microsoft Project schedules in .MPP or .XML format, making it easier to transition without rebuilding plans from scratch. The platform supports detailed project controls such as Gantt charts, critical path scheduling, dependencies, constraints, calendars, baselines, milestones, resource leveling, and earned value analysis. ProjectLibre AI converts natural-language prompts in any language into structured project plans containing tasks, durations, dependencies, resources, milestones, and work breakdown structures. ProjectLibre Desktop is a widely adopted open-source replacement for Microsoft Project, with over 8.7 million downloads in more than 193 countries. The software is available in 31 languages and is used by over 1,700 universities around the world. ProjectLibre Cloud is a browser-based SaaS platform that brings AI-assisted planning and collaborative project management to teams. It also provides organizations with a practical migration path as Microsoft Project Online approaches its scheduled retirement on September 30, 2026. Key features: - Advanced scheduling with CPM, dependencies, constraints, calendars, baselines, critical path, and float - Enterprise resource planning with leveling, shared resource pools, RBS, and OBS - Monte Carlo simulations for project risk analysis - DCMA-based schedule quality auditing - Earned value and performance metrics, including SPI, CPI, TCPI, and cost rates - Portfolio and multi-project administration - Role-based permissions for project teams - Real-time, browser-based collaboration - AI Copilot for generating complete project plans from natural-language instructions in any language - Microsoft Project .MPP importing and feature compatibility for smoother migrations - Gantt charts, network diagrams, etc.

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.
