About Gantt Chart Generator

Create Gantt charts for project planning with tasks, dependencies, and duration. Part of the DevTools Surf developer suite. Browse more tools in the Diagrams & Workflows collection.

Use Cases

• Visualize sprint timelines and feature delivery dates for stakeholder status updates.
• Map out a product launch sequence with dependencies between marketing, engineering, and ops tasks.
• Create a resource allocation view showing which team members are assigned across overlapping tasks.
• Generate a quarterly roadmap visual for board presentations.

Tips

• Define task dependencies before setting dates — the chart auto-adjusts successors when a predecessor's end date shifts.
• Use milestones (zero-duration tasks) to mark deliverable dates that external stakeholders track.
• Export to PNG at 2x resolution for presentations to keep text crisp on high-DPI displays.

Fun Facts

• The Gantt chart was developed by Henry Gantt around 1910-1915 and was used extensively in World War I to manage munitions production at US Army arsenals.
• The first software Gantt chart tool was MacProject, released by Apple in 1984 — it was bundled with the original Macintosh and cost $195.
• Despite being over 100 years old, the Gantt chart remains the dominant project visualization format; a 2019 PMI survey found 78% of project managers used Gantt charts regularly.

FAQ

Does it support task dependencies?

Yes — finish-to-start, start-to-start, and finish-to-finish dependency types are supported. Changing a predecessor automatically shifts dependent tasks.

Can I assign resources to tasks?

Each task accepts a assignee name and color-coded resource lane. This produces a resource-loaded Gantt that highlights over-allocation visually.

What export formats are available?

PNG, SVG, and JSON (for re-importing later). The JSON export preserves all task data, dependencies, and date offsets.
