GanttProject vs Wakapi
A side-by-side editorial comparison of GanttProject and Wakapi — release velocity, themes, recent moves, and the top alternatives to consider.
GanttProject vs Wakapi: 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 Wakapi?
A critical auth bypass lands in the middle of Wakapi's slow identity rebuild.
Wakapi's recent releases cluster around identity and deployment rather than time tracking itself: OpenID Connect login, then an OIDC-only mode, multiple API keys per user, and a switch from Alpine to a distroless nonroot container image. The 2.17.x line has carried two security fixes now — a responsibly disclosed issue in 2.17.3, and a critical authentication bypass in 2.17.6 caused by a shared cache key namespace. Release notes are mostly bare issue numbers, so several entries state that something changed without saying what.
GanttProject vs Wakapi: 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.
Wakapi
2.5PM
A critical auth bypass lands in the middle of Wakapi's slow identity rebuild.
◆ Current state
Wakapi's recent releases cluster around identity and deployment rather than time tracking itself: OpenID Connect login, then an OIDC-only mode, multiple API keys per user, and a switch from Alpine to a distroless nonroot container image. The 2.17.x line has carried two security fixes now — a responsibly disclosed issue in 2.17.3, and a critical authentication bypass in 2.17.6 caused by a shared cache key namespace. Release notes are mostly bare issue numbers, so several entries state that something changed without saying what.
◆ Where it's heading
The direction is a self-hosted tool making itself deployable somewhere other than one developer's server. External identity providers, an option to disable local login entirely, per-key credentials and a container that runs as a nonroot user are the requirements that come from someone else's security review. The 2.17.6 bypass sits awkwardly against that: a cache keyed without proper namespacing is exactly the class of bug that multi-tenant deployment surfaces, which suggests the auth work is now being exercised harder than the code was written for. Releases have also thinned to roughly one a month from a much faster earlier cadence.
◆ Prediction
The identity and packaging thread is the only sustained one in this feed, so further hardening in that area is the most likely continuation; the sparse release notes make anything more specific guesswork.
