GanttProject vs Atlassian
A side-by-side editorial comparison of GanttProject and Atlassian — release velocity, themes, recent moves, and the top alternatives to consider.
GanttProject vs Atlassian: at a glance
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 Atlassian?
In two days Atlassian shipped AI into Trello, opened LLMs to Forge developers, and made Jira dispatch coding agents.
Three substantial releases landed inside 48 hours. Jira Automation can now trigger GitHub Copilot, Cursor or Claude Code as a step in any rule, with conditions deciding when work hands off. The Forge LLMs API went generally available, giving any app developer model access as a platform primitive. Trello got seven AI features at once, extended to every paid user on Standard, Premium and Enterprise. Rovo Search, Chat and Agents can now read documents the user already has access to in Google Drive, SharePoint and OneDrive. The remaining entries are an internal ML engineering write-up and an analyst-report announcement.
GanttProject vs Atlassian: editorial side-by-side
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.

◆ Where it's heading
Atlassian is building the layer beneath other people's agents rather than competing feature-for-feature with them. Automation becomes the dispatcher that decides when a coding agent runs; Forge becomes the place third-party apps get model access without their own inference contracts; Rovo becomes the retrieval surface over documents Atlassian does not host. The Trello release is the consumer-facing counterpart, and shipping it to all paid tiers rather than the top one suggests AI is being treated as table stakes rather than an upsell.
◆ Prediction
Expect the agent-dispatch pattern to spread from Jira Automation to other Atlassian surfaces, and Rovo's connector set to keep widening to systems Atlassian doesn't own.
