GanttFather vs Microsoft Project
GanttFather is a modern free Gantt + Kanban tool covering core scheduling, dependencies, critical path, and AI agent integration for 4 projects with unlimited users at $0. Microsoft Project is the legacy enterprise standard with deep Microsoft 365 integration and per-seat pricing starting at $10/user/month with no standalone free plan. GanttFather wins on price, onboarding speed, real-time collaboration, browser-only access, and native MCP agent support. Microsoft Project wins on enterprise M365 integrations, advanced auto-leveling, and on-premise deployment via Project Server.

When is Microsoft Project the better choice?
Microsoft Project is the better choice when you're locked into the Microsoft ecosystem and need enterprise features that justify per-seat pricing.
- Your organization mandates Microsoft 365 / SharePoint / Power BI integration.
- You need on-premise deployment via Project Server for compliance reasons.
- You require advanced auto-leveling of resources across hundreds of tasks.
- You manage portfolios with multiple baselines per project.
- You need a language Microsoft supports that GanttFather does not.
- Per-seat licensing is already in your budget.
When is GanttFather the better choice?
GanttFather is the better choice when you want Microsoft Project's core scheduling power without the cost, install friction, or per-seat pricing.
- You're a small team, freelancer, startup, or non-profit and $10/user/month is a non-starter.
- You want browser-based access without installing the desktop client.
- You need real-time multi-user editing without Microsoft 365 co-authoring constraints.
- You want AI agents (Claude, Cursor, Windsurf) to manage tasks via Model Context Protocol natively.
- Your stakeholders want a public read-only link to view the timeline without Microsoft accounts.
- You prefer slot-based pricing over per-seat fees.
Frequently asked questions: GanttFather vs Microsoft Project
Is GanttFather a free alternative to Microsoft Project?
Yes. GanttFather provides the core scheduling features Microsoft Project users rely on — drag-and-drop timeline, all four dependency types with lag/lead, critical path, baseline tracking, and Excel sync — at no cost for 4 projects with unlimited users. Microsoft Project starts at $10/user/month with no free tier.
Can I open .mpp files in GanttFather?
Not directly. GanttFather imports from Excel (.xlsx). The recommended migration path from Microsoft Project: export the .mpp to .xlsx via File → Export → Save Project as File, then import the .xlsx into GanttFather. Tasks, dates, dependencies, and assignees are preserved.
When is Microsoft Project still the right choice?
Microsoft Project remains the right tool for enterprise teams with deep Microsoft 365 integration needs (SharePoint, Power BI, Teams), mandatory on-premise deployment, advanced resource leveling, or government/compliance requirements that mandate Microsoft licensing. For everything else, the per-seat pricing rarely justifies itself.
Does GanttFather support critical path like Microsoft Project?
Yes, with one important difference: critical path is free in GanttFather. Microsoft Project includes it but only at the $10/user/month tier. GanttFather computes critical path automatically across all dependency types and visualizes it directly on the Gantt timeline.
How does AI integration compare?
Microsoft offers M365 Copilot as a paid add-on (~$30/user/month) integrated with Project. GanttFather provides a native Model Context Protocol (MCP) server at no extra cost — any MCP-compatible AI agent (Claude Desktop, Cursor, Windsurf, VS Code) can read tasks, manage dependencies, and update the Gantt programmatically.
