About Le Gantt
What is Le Gantt?
Le Gantt turns a Trello board or a Basecamp project into a Gantt chart. The Trello power-up is free to use. The Basecamp chart has a 14-day free trial.
What Le Gantt does
The Trello power-up makes a visual timeline with drag-and-drop task dependencies, and dates can be scheduled on that timeline. The page says it stays 100% Trello-native, with no account and no external database. The Basecamp chart syncs both ways: dates changed on the chart write back to Basecamp. Move one task and every dependent date shifts forward. A critical path, milestones, baselines, progress, weekends and holidays, bulk move, custom columns, assignees, and date constraints are listed.
Who Le Gantt is for
Someone who already keeps tasks in Trello or Basecamp and wants those tasks on a timeline, including dependencies, milestones, and a deadline.
How Le Gantt works
Add Le Gantt to Trello or to Basecamp. Drag dependencies, then schedule dates on the timeline. Move one task and every dependent date shifts forward. Pin a task to a hard date, must start on or start no earlier than, and auto-scheduling works around that pin. Skip weekends and holidays so a task does not start or finish on a day off. Freeze the plan with baselines and compare it against where the work stands. Overdue tasks turn red and due-soon tasks turn amber.
