How the syntax works

Every Gantt chart starts with a keyword, and the lines below describe hierarchy and relationships through indentation and symbols. The canvas updates as you type.

Frequently asked questions

Do I need an account to make a Gantt chart?

No. Every feature is free and open, you can start the moment the page loads, and exports are unlimited.

What formats can a Gantt chart be exported to?

PNG and SVG. SVG is a vector format, so it stays sharp at any zoom level and works well in documents and slide decks.

How do I share a Gantt chart with someone?

The share button produces a link with the diagram code embedded directly in it. Whoever opens it sees the same diagram, with no login required.
