# Gantt chart maker — project timeline, no upload

> Free Gantt chart maker: plan tasks, sections, and dependencies in Mermaid and render a project timeline. Everything runs locally — export SVG, PNG, or PDF.

Plan tasks, sections, and dependencies in Mermaid and render a Gantt timeline for your project. It all runs locally, and you can export SVG, PNG, or PDF.

A Gantt chart turns a plan into a picture of what happens when. Writing it in Mermaid keeps the plan as text you can version and paste into a doc, while dependencies mean shifting one task ripples through the timeline instead of forcing manual redraws.

Sections keep larger plans legible by grouping tasks into phases, and status markers make the same chart useful as a living status report, not just an initial plan.

Brainstorm the plan first as a Mind map, break work into steps with a Flowchart, or drop into the Playground for other diagram types.

## How to

1. **Set the dates.** Choose the date format and title for the plan.
2. **Add sections & tasks.** Group tasks into sections with start dates or dependencies.
3. **Mark progress.** Flag tasks as done, active, or scheduled.
4. **Export.** Download the timeline as SVG, PNG, or PDF.

## FAQ

### How do I make a Gantt chart without a project tool?

Describe tasks in Mermaid's gantt syntax with durations or dependencies (after des1, 4d) and it draws the timeline — no subscription project app required.

### Can tasks depend on each other?

Yes. Chain tasks with 'after' so a task starts when its predecessor ends, and the timeline shifts automatically when you change a duration.

### Can I show status like done or in-progress?

Yes — mark tasks done or active and they render with distinct styling, giving a quick read on where the project stands.

### Is my project plan uploaded?

No. The chart renders in your browser, so your schedule and task names stay private.
