Online Gantt
Free Gantt Chart Maker
Plan a project on a timeline with dependencies, progress, and drag-to-reschedule, all from a table you already have.
A Gantt chart shows tasks as bars across time, so you can see what happens when and what depends on what. In ZenBuild the Gantt is a view of a table built from your start and due date columns, so the same records also drive your grid and board.
Bars from your dates
Two date columns, a start and a due, place each task on a day, week, month, or quarter axis.
Dependencies and progress
Link tasks to draw dependency arrows, and fill each bar by a percent or status column.
Drag to reschedule
Drag a bar to move a task or drag its edges to change its duration; the dates update automatically.
Free, in the browser
The Gantt view is available on every plan with nothing to install.

Frequently asked questions
Is the Gantt chart maker free?
Yes. The Gantt view is built in and available on every plan, including the free Starter plan, subject to your table and record limits.
What do I need to make a Gantt chart?
A table with two date columns: a start date and an end or due date. Every row with both becomes a bar on the timeline.
Can I show dependencies between tasks?
Yes. Add a link column pointing each task at its predecessors and select it as the Dependencies field to draw arrows.
Can I track progress?
Yes. Choose a percent-format number or a status select as the progress source, and each bar fills to show how complete the task is.
