# Gantt Chart Pro Limits
Gantt Chart Pro works in two tiers: a Free plan with everything a small project needs, and a Premium plan that removes the size caps and unlocks the advanced features. Here is exactly what each plan allows.
Gantt Chart Pro runs inside Microsoft Teams. Add it as a tab in a channel or chat. It is not offered as a standalone web or desktop app.

When you reach a Free limit or select a Premium-only feature, Gantt Chart Pro shows an upgrade prompt instead of blocking you silently. Your existing data is never removed.
# What the Free limits mean in practice
- 5 main tasks: once your chart has 5 top-level tasks, adding a 6th prompts you to upgrade.
- 1 subtask per task: each task can have a single subtask on the Free plan. Premium removes this cap.
- 3 participants per task: trying to assign a 4th participant to a task shows the message "Only 3 participants can be added in the free version".
- No colors, milestones, filter, or export: these features are visible, but selecting them prompts you to upgrade to Premium.
# Common questions
# What happens when I hit a limit?
You are shown an upgrade prompt. Your existing data is never lost. You simply cannot add beyond the Free cap or use a Premium-only feature until you upgrade.
# Does every teammate need Premium?
No. Only users who need Premium capabilities require a license. Others can keep using the tab within the Free limits. For details, see do all channel users need a license.
# Where do I upgrade?
From the Teams-Pro Admin Center (opens new window), where you can purchase, manage seats, and start a trial.
