Free Gantt chart online
Most "free Gantt" tools cap critical path and baselines at the paid tier. Onplana's free plan ships the full Gantt — critical path, four dependency types with lag, saved baselines, native .mpp import. Unlimited projects, no time limit, no credit card.
What's actually free
Most "free Gantt" tools have a long list of "Pro features" that turn out to be the things you actually need. Onplana's free plan is honest.
- Interactive Gantt chart with drag-and-drop scheduling
- Automatic critical path computation and highlighting
- All four dependency types: Finish-to-Start, Start-to-Start, Finish-to-Finish, Start-to-Finish
- Lag and lead values in days, hours, or percentage
- Saved baselines with shadow overlay on the Gantt
- Native .mpp import (no XML conversion intermediate, no Project Desktop license needed)
- Microsoft Project XML (MSPDI) import
- Unlimited projects
- Up to 5 members
- No time limit, no credit card, no trial expiry
When you'll outgrow the free plan
More than 5 members? You'll move to STARTER ($7/seat/mo) or PRO ($12/seat/mo). Need AI features (plan generation, risk detection)? PRO. Need formal stage-gate governance or audit-grade compliance? ENTERPRISE. The Gantt itself stays the same on every plan — you upgrade for capacity and capabilities, not for a basic Gantt feature you should never have been gated out of.
