Celoxis vs GanttProject: at a glance
What is Celoxis?
Celoxis publishes buyer guides at a pace its changelog never matches.
Celoxis is a project and portfolio management platform, and the crawled feed carries only marketing content: end-to-end PPM guides, a video explainer roundup, a four-part engineering project management series, and vertical buyer guides for film production and renewable energy. Several posts land on the same day. No releases appear in the window.
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.

◆ Current state
Celoxis is a project and portfolio management platform, and the crawled feed carries only marketing content: end-to-end PPM guides, a video explainer roundup, a four-part engineering project management series, and vertical buyer guides for film production and renewable energy. Several posts land on the same day. No releases appear in the window.
◆ Where it's heading
The visible program is vertical and comparison coverage aimed at software-selection searches, including guides that name competitors and place Celoxis among the options. It is a demand-generation strategy running at high cadence; the product's own development is not observable through this feed.
◆ Prediction
Expect the engineering best-practices series to continue and more vertical buyer guides on the same rotation. No product prediction is supportable from these entries.
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.
