Create a Gantt chart from a task list — no account or API key needed. YOU author the plan: list the tasks in execution order with realistic working-day durations and dependencies (0-based positions of earlier tasks; use { task, type, lag } for start-to-start/finish-to-finish links or lag). Milestones have duration 0. LoopGantt schedules it with its critical-path engine and returns a picture of the chart, the dates, the critical path and a link where the user can view, export (PNG/PDF) and save the chart. Always show the user the link.

Compute a schedule without storing anything: dates, critical path, float and project end for a task list (same input shape as create_gantt; name optional). Use it to answer "what is the critical path?", "when would this finish?", "how much slack does X have?". Use create_gantt when the user wants a chart they can open.

List LoopGantt's industry project templates with task counts and typical durations. Pick one, fetch it with get_template, adapt it, then create_gantt.

Get one industry template by slug: its task list with durations, ready to adapt and pass to create_gantt.
