Free Gantt Chart Maker

Free online Gantt chart maker

Plan a project on a clear timeline without installing anything. Group work into phases, set start and end dates for each task, add milestones for key deadlines and track progress as the plan moves. It works for product launches, software releases, construction schedules, event plans and team roadmaps.

Your plan stays on your device. The tool autosaves to your browser and lets you download the whole plan as a JSON file, so you control where it lives and who gets a copy.

Gantt Chart Maker FAQs

Common questions about planning with this tool.

Is this Gantt chart maker free?

Yes. You can create, edit and save as many project plans as you like. There is no account, no sign-up and no usage limit.

Where is my project data stored?

In your own browser. The chart autosaves to local storage on your device and is not uploaded to a server. Clearing your browser data removes the draft, so use Save project to keep a copy.

How do I back up or share my plan?

Click Save project to download a JSON file. Send that file to a teammate, or open it later with Open project on any device. Opening a file replaces the plan currently in the workspace.

How do I start over?

Click Reset to return to the blank sample project. A confirmation appears first, and an Undo button is available right after the reset.

How do I add a milestone or mark a task as a delay risk?

Use the calendar icon on a phase row to add a milestone. For a delay risk or progress, hover over a task, click its dates and use the Progress slider and the Delay risk switch.

Can I export the chart as an image or PDF?

Image and PDF export are not built in yet. For now, take a screenshot or use your browser's print option. The JSON file is the full, editable copy of your plan.
