A Gantt chart lays project tasks on a calendar: each bar is a task with a start and a duration, rows group into workstreams, and dependencies chain bars so a slip is visible downstream. It answers the two questions every plan gets asked — what happens when, and what is waiting on what.
Common use cases
Design, build, launch — put each workstream in a section and let dependencies show the critical path to the date that matters.
A text-based timeline lives in the repo next to the work — update a date in one line instead of dragging bars in a planning tool.
Export a clean SVG or PNG of the current plan for the deck — the presentation-ready layout means no screenshotting a cluttered tool.

Frequently asked questions
How do I make a Gantt chart online for free?
Type your plan as text in the editor above — a section per workstream, a line per task with a start date or an after dependency. The timeline renders live and exports to SVG or PNG without signup.
How do I make one task start after another finishes?
Give the first task an id, then start the second with after that id: Frontend: fe, after visual, 10d. Chains of after dependencies are how the critical path shows up visually.
Do I have to set exact dates for every task?
No — only anchor tasks need dates. Everything else can hang off them with after dependencies and durations (5d, 2w). Shift the anchor date and the whole dependent chain moves with it.
Can I use this instead of a project management tool?
For planning snapshots, yes — it is a diagram, not a tracker: no assignees, progress syncing, or notifications. Its strength is that the plan is text — it diffs in version control and updates in seconds for the next status deck.
Can I generate the chart from AI output?
Yes. Ask any AI assistant for "a Mermaid gantt chart of …", paste the code here, and it renders with a beautified layout. A command-line tool and editor plugins let agents and scripts export charts directly.
Is this Gantt chart maker really free?
Yes. Anonymous use covers live preview, beautify, and SVG/PNG export with a small watermark; a free account removes the watermark. Per-month export quotas are listed on the pricing page.
