What is GanttProject?

A desktop Gantt tool on a multi-year cadence, tethering itself to its own cloud

GanttProject is a desktop project scheduling application released every one to three years, with occasional build-only tags in between. The most recent feature update, 3.3, added calculated columns driven by SQL expressions in the task table, project-relative week numbers, and a native Apple Silicon package. The intervening tags are packaging work rather than product: restoring Linux and Windows builds, and producing both Intel and Silicon macOS packages.

What is OpenProject?

OpenProject's MCP Server gains write access — AI agents can now create tasks, add comments, and manage relations.

OpenProject 17.8.0 marks the most significant AI integration milestone in the product's history: the MCP Server can now create and update work packages, add comments, and manage relations — moving from a read-only query layer to a write-capable AI agent interface. The same release adds multiple target versions per work package, sprints and milestones to the project timeline, and relation display in the free Community edition. OpenProject 17.7.0 laid the organizational management foundation: departments, work-related user attributes, and individual work schedules for capacity planning.

GanttProject vs OpenProject: editorial side-by-side

G0.0

A desktop Gantt tool on a multi-year cadence, tethering itself to its own cloud

◆ Current state

GanttProject is a desktop project scheduling application released every one to three years, with occasional build-only tags in between. The most recent feature update, 3.3, added calculated columns driven by SQL expressions in the task table, project-relative week numbers, and a native Apple Silicon package. The intervening tags are packaging work rather than product: restoring Linux and Windows builds, and producing both Intel and Silicon macOS packages.

◆ Where it's heading

The through-line since 3.0 is a desktop application acquiring a service tail. GanttProject Cloud arrived in 3.0 alongside a bundled Java runtime and an update channel, 3.1 added a connection toggle and pulled a shared human-resource database from the cloud, and 3.2 rewrote the task table with filtering and non-destructive sorting. By 3.3 the table is programmable through SQL expressions. Each release deepens either the cloud tie or the table, which are the two places a desktop planner can still differentiate — but the cadence means any given year may show only a packaging fix.

◆ Prediction

Expect the next feature release to extend calculated columns or the cloud collaboration surface; on this cadence it is unlikely to arrive quickly, and the entries give no indication of timing.

O6.3

OpenProject's MCP Server gains write access — AI agents can now create tasks, add comments, and manage relations.

◆ Current state

OpenProject 17.8.0 marks the most significant AI integration milestone in the product's history: the MCP Server can now create and update work packages, add comments, and manage relations — moving from a read-only query layer to a write-capable AI agent interface. The same release adds multiple target versions per work package, sprints and milestones to the project timeline, and relation display in the free Community edition. OpenProject 17.7.0 laid the organizational management foundation: departments, work-related user attributes, and individual work schedules for capacity planning.

◆ Where it's heading

The two-track development pattern is clear: broader project management capabilities for enterprises (resource management, capacity planning, PM² methodology support) and a rapidly maturing AI interface through the MCP Server. The progression from read-only MCP to write-capable MCP is a qualitative shift — AI assistants become active project participants rather than passive query tools. The XWiki integration in 17.6.0 shows the platform also extending into enterprise knowledge management.

◆ Prediction

The logical next step is workflow automation via the MCP Server — AI agents that can trigger status transitions, query resource availability from the 17.7.0 capacity data, or auto-assign work packages based on department membership. The data model is in place; the automation layer is the missing piece.
