GanttProject vs RentRedi
A side-by-side editorial comparison of GanttProject and RentRedi — release velocity, themes, recent moves, and the top alternatives to consider.
GanttProject vs RentRedi: 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 RentRedi?
RentRedi is rebuilding around multi-property operators, with its first model-facing feature at the tenant boundary.
RentRedi ships weekly and the recent window is dense with structural work rather than surface features. Portfolios introduced a grouping primitive that later releases assume, lease editing removed a delete-and-recreate workaround, and documents got a global tab with folders. The AI Maintenance Helper is the product's first model-facing capability, and it sits at intake where tenant-written text enters the system.
GanttProject vs RentRedi: 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.
RentRedi
7.5PM
RentRedi is rebuilding around multi-property operators, with its first model-facing feature at the tenant boundary.
◆ Current state
RentRedi ships weekly and the recent window is dense with structural work rather than surface features. Portfolios introduced a grouping primitive that later releases assume, lease editing removed a delete-and-recreate workaround, and documents got a global tab with folders. The AI Maintenance Helper is the product's first model-facing capability, and it sits at intake where tenant-written text enters the system.
◆ Where it's heading
Two arcs run in parallel. One is operational maturity: the product is closing the gaps that force a growing landlord toward heavier commercial suites — multi-entity grouping, lease lifecycle edits, document organisation, portfolio-level performance. The other is selective use of models at the points where unstructured input arrives. Notification preferences fit the first arc: an account that now spans portfolios, leases and maintenance queues generates more alerts than a single toggle can manage.
◆ Prediction
The most likely next move is extending AI beyond maintenance intake to the other place free text enters the product — applications and tenant messaging — while the portfolio primitive keeps absorbing reporting surfaces.
