GanttPM vs OnlineGantt
OnlineGantt: Zero-friction, browser-based Gantt charting
OnlineGantt makes it fast to open a browser and start dragging bars — no signup required. But it edits dependencies through a dialog rather than letting you drag-to-connect on the canvas, and it has no critical path calculation at all, so you never actually know which delays matter. GanttPM keeps the zero-friction local start but adds a real CPM engine and five synced views underneath it.

Who is each best for?

Start Free →Very simple, single-timeline projects where dependency editing via a dialog and no critical path calculation are acceptable trade-offs for minimal setup.
OnlineGantt's free tier is local-file-only; its cloud tier runs $4–5/user/month after a 7-day trial. GanttPM is free to use locally with no account, and $9.99/month flat for cloud sync and collaboration — not priced per user.
