Gantt chart guides

By Prairie Loom editorial team Verified against the current GanttProject release on GitHub Releases

Step-by-step notes for installing GanttProject, proving a local schedule, importing plans, and comparing with commercial tools. Start with your operating system install article, then read safety and first run before you migrate an old file.

Windows readers should prefer the MSI asset on GitHub Releases. macOS readers can use Homebrew or the matching DMG. Linux readers on Debian-family desktops can install the official deb. Every longer article below links back to those doors so you do not rely on mirror sites.

When you finish an install guide, open the first-run checklist and save a tiny project with real dependencies. Export once for stakeholders who will never open the desktop app. Only then attempt imports from Microsoft Project or spreadsheets.

Install

  • Windows install — Install a gantt chart on Windows with ganttproject-*.msi from GitHub Releases. Prefer MSI over EXE for a local GanttProject schedule.
  • macOS install — Install a gantt chart on macOS with Homebrew cask ganttproject or the silicon/intel DMG from GitHub Releases for local GanttProject work.
  • Linux install — Install a gantt chart on Debian-family Linux with the ganttproject_*-1_all.deb from GitHub Releases for a desktop GanttProject build.

How-to

  • Is it safe — Is this gantt chart software safe? GPL-3.0 GanttProject notes, GitHub Releases downloads, SmartScreen habits, and wrappers to skip.
  • First run — First-run gantt chart checklist: create tasks, link bars, save .gan, export PDF, then consider imports and resources in GanttProject.
  • Windows MSI notes — Why Windows gantt chart installs prefer ganttproject-*.msi over EXE from GitHub Releases tags in this GanttProject guide.
  • Troubleshooting — Fix common gantt chart install and schedule problems: SmartScreen blocks, missing links, bad imports, and update confusion with GanttProject.
  • Update and uninstall — Update or uninstall a gantt chart app from GitHub Releases or Homebrew without losing your GanttProject .gan project files.
  • Export PDF — Export a gantt chart to PDF, HTML, or PNG from GanttProject so stakeholders can read the schedule without installing the desktop app.

Migrate

  • Import MS Project — Import into a gantt chart from Microsoft Project after proving a local file. Expect cleanup on fields and links in GanttProject.

Compare

  • vs spreadsheets — When a desktop gantt chart beats spreadsheet timelines, and when a sheet sketch is enough for early planning work.
