Free Gantt Chart Maker for Linux and Chromebook

Linux and Chromebook users consistently get the worst gantt chart recommendations. Most guides point to MS Project (Windows only), GanttProject (requires Java and can be painful on modern distros), or web tools that look fine until you hit a paywall on export. The cleanest solution runs in your browser right now — any distro, any browser, zero install.

The Linux Gantt Chart Problem

Linux users searching for gantt chart software run into the same dead ends repeatedly:

• GanttProject — free and functional but requires Java (openjdk). On modern Debian/Ubuntu systems the JDK install is straightforward; on Arch, Fedora, or minimal distros it adds complexity. Abandoned-looking UI on HiDPI displays.
• ProjectLibre — similar story. Java-based, .AppImage or package install required. Works but heavy for simple timelines.
• Planner (GNOME) — native GTK app, last updated years ago. Functional for basic gantt charts but not maintained.
• LibreOffice Calc gantt — manual setup using conditional formatting. Takes an hour to configure properly and breaks when you add tasks.

A browser-based tool removes every one of these friction points. Firefox, Chrome, and Chromium are installed on virtually every Linux desktop. No additional packages, no compatibility checking, no snap vs flatpak debate.

Browser Compatibility on Linux and Chrome OS

Linux (tested distros):

• Ubuntu 22.04/24.04 — Firefox and Chrome, confirmed working
• Fedora 39/40 — Firefox (default), confirmed working
• Arch Linux — Firefox and Chromium, confirmed working
• Debian 12 — Firefox ESR, confirmed working
• Pop!_OS — Chrome and Firefox, confirmed working

Chrome OS / Chromebook:

The tool runs natively in Chrome on any Chromebook. No Android app, no Linux container needed. The page loads, you type your project, you export. The PNG downloads directly to your Files app.

Works offline after the initial page load — Chrome caches the necessary assets. If you lose your internet connection mid-session, the render and export functions continue working.

Using Exported Gantt Chart Files on Linux

Both PNG and SVG exports integrate cleanly with the Linux desktop ecosystem:

PNG files:

• Open and edit in GIMP, Eye of GNOME, Gwenview, or any image viewer
• Insert into LibreOffice Impress or Writer directly
• Attach to emails in Thunderbird
• Upload to Confluence, Notion, or any web-based documentation tool

SVG files:

• Edit in Inkscape — the SVG is fully layered and editable
• Open in Firefox or Chrome for a clean full-resolution view
• Import into LibreOffice Draw or Impress (File > Insert > Image)
• Convert to PDF using Inkscape's command line: inkscape input.svg --export-type=pdf -o output.pdf

Chromebook-Specific Workflow

Chromebooks are increasingly popular in education and for lightweight professional use. Most gantt chart tools either require a desktop download or have collaborative features that push you toward a Google Workspace account. The browser gantt tool needs neither.

Student workflow on Chromebook:

1. Open the gantt chart tool in Chrome
2. Type your research project tasks, dissertation timeline, or class project schedule
3. Export PNG
4. Open Google Slides, insert image, drop the PNG on your timeline slide

Business workflow on Chromebook:

1. Open the gantt chart tool
2. Type your project tasks with dependencies
3. Export SVG
4. Open Google Docs, Insert > Image > Upload from computer

No Google Drive sync needed, no third-party Chrome extension, no Android app installation.

Frequently Asked Questions

Is there a native Linux gantt chart app that is still maintained?

GanttProject is the most maintained free native option (requires Java). ProjectLibre is another. Both are functional but require installation. A browser-based tool is faster to use for simple timelines and requires no installation on any Linux distro.

Does this gantt chart tool work on Chromebook without Linux (Crostini)?

Yes — it runs natively in the Chrome browser on Chrome OS. No Linux container, no Android app, no developer mode required.

Can I use this tool on a Raspberry Pi running Linux?

Yes, if you have Chromium or Firefox installed (both available on Raspberry Pi OS). Performance may be slower on Pi 3 models; Pi 4 and 5 handle it without issue.
