Project planning,
back on your desktop.

JeeGantt is a streamlined, cross-platform desktop project planner — a lightweight alternative to Microsoft Project. Tasks, WBS, dependencies, resources and an interactive Gantt chart, all in a single local file. No account, no cloud.

Everything you need, nothing you don't

A focused feature set, modelled on professional project management tools.

Interactive Gantt

Task and summary bars, milestones, dependency links, critical-path highlighting, progress fill, drag-to-move and a baseline overlay.

WBS task grid

Hierarchical tasks with inline editing, indent/outdent, link/unlink, move up/down with automatic WBS renumbering and hide/show columns.

CPM scheduling engine

Forward/backward passes over a working calendar, four dependency types (FS/SS/FF/SF) with lag, total slack, critical path and cycle detection.

Resources & costs

Assignments, workload, over-allocation detection and cost roll-up, with costs formatted by currency and locale.

Baselines

Capture a planned snapshot and compare start/finish variance directly on the Gantt chart.

PDF reports

Export the Gantt chart, progress reports and resource-workload reports to PDF, with a time axis following the project scale.

Privacy and control

One file. Fully local. No cloud.

Every project lives in a single .jgp file on your machine — atomic saves with a backup, undo/redo and a workspace session. No account to create, nothing to sync, nothing leaves your computer.

  • Single-user, offline-first
  • Atomic save with automatic backup
  • Undo / redo and recent files

Works with the tools you already use

Import and export across the formats your team and clients expect.

Note: no open-source library can write the binary .mpp format. JeeGantt reads .mpp fully and exports the interoperable MS Project XML (MSPDI), which Microsoft Project opens natively.

The same app on Windows, macOS and Linux

No Electron, no web wrapper: JeeGantt is a native desktop app, and your project file opens the same on every OS.
