The free Gantt chart maker
Type your tasks, how long they take and what they wait for, and the Gantt chart schedules itself. No dragging bars, no signup, no software to install.
GanttCharts.app is the free, no-signup Gantt chart maker. Type your tasks one per row, with how many working days each takes and what it waits for, and the Gantt chart schedules itself: dates, dependencies, milestones and the critical path are worked out automatically, so changing one task moves every task after it. Downloads come with a free QueryChart account, and cloud save, sharing, and version history live in QueryChart, the platform it is built on.
How it works
One row per task. Columns set the task's name, its duration in working days, what it depends on, a fixed start date if it has one, its progress, and its owner. Change a duration and every task after it moves; a duration of 0 is a milestone. Paste a task list from Excel or Google Sheets and the plan assembles itself. Your work saves in your browser; a free QueryChart account downloads it as a PNG.

- GlossaryThe scheduling words behind a Gantt chart, defined: finish-to-start and the other dependency types, lag and lead, float (slack) and working days.
- Glossary: Dependency typesThe four Gantt chart dependency types explained with examples: finish-to-start (FS), start-to-start (SS), finish-to-finish (FF) and start-to-finish (SF).
- Glossary: Lag and leadLag is a wait between two linked tasks; lead is an overlap. What each means in a Gantt chart, with examples, and how to write them on a dependency.
- Glossary: Float (slack)Float, also called slack, is how far a task can slip before it delays the project's end. Total float, free float, zero float and the critical path, with an example.
- Glossary: Working daysWhy a five-day task takes a calendar week: Gantt chart durations count working days, not calendar days. How weekends, start dates and lags are counted.
