A Gantt chart that lives on your machine

No project-management account required. Add tasks with start and end dates, assign owners, set how far along each one is, and the chart auto-scales to fit your whole project — with week or month gridlines and a line marking today. Reorder tasks by dragging, switch the time scale, then export a high-resolution PNG for a deck or a JSON file you can re-import later. Everything stays in your browser.
