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 settles into patch work after 17.7 shipped resource management.

17.7.0 was the substantial release — a resource management module with departments and work schedules, pushing OpenProject past task tracking into staffing. The two releases since are patches. 17.7.2 fixes four bugs, among them project-level hourly rates that could not be adjusted and non-working days silently dropped when saved while a reschedule job was running — both in the scheduling and cost areas 17.7 had just expanded.

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 settles into patch work after 17.7 shipped resource management.

◆ Current state

17.7.0 was the substantial release — a resource management module with departments and work schedules, pushing OpenProject past task tracking into staffing. The two releases since are patches. 17.7.2 fixes four bugs, among them project-level hourly rates that could not be adjusted and non-working days silently dropped when saved while a reschedule job was running — both in the scheduling and cost areas 17.7 had just expanded.

◆ Where it's heading

The release rhythm is a feature minor followed by a short tail of patches repairing the surface it just added, and this tail sits squarely in resource-management territory. Rate and non-working-day bugs are the predictable cost of shipping scheduling and cost tracking together. For self-hosted operators the advice does not change between these releases: take the patch.

◆ Prediction

Expect one or two more 17.7.x patches against the resource management surface before 17.8 opens a new feature line.
