Real project management, not just bars on a timeline.
GanttPM runs a true CPM engine under the hood (forward/backward pass scheduling, slack calculation, and automatic cascade rescheduling), surfaced through five views of the same project data.
Same data. Whichever view fits the conversation.
Switch views instantly. A change in one shows up everywhere else, immediately.
Gantt
True critical-path scheduling with drag-to-reschedule, dependencies, and automatic cascade updates.
List
A dense, spreadsheet-like view of every task, field, and WBS level, built for fast bulk edits.
Kanban
Drag tasks across status columns when you want to think in workflow, not dates.
Calendar
See what is due, day by day and week by week, without opening the full timeline.
Resources
A workload heatmap that shows overallocation before it becomes a problem.
Built for real project management
Real critical-path scheduling
A true CPM engine with forward/backward pass, slack calculation, and automatic cascade rescheduling. FS, SS, FF, and SF dependencies with lag.
Import Microsoft Project files
Bring in .xml (MSPDI) files with tasks, WBS hierarchy, dependencies, resources, and assignments intact, no re-entry required.
AI project plan generation
Type a plain-language description of your project and let AI generate a real task list: titles, dates, milestones, and dependencies, ready to refine in the Gantt chart.
Resource planning built in
Assign people with allocation percentages and see workload as a heatmap, so overallocation is visible before it is a problem.
Baselines for tracking drift
Snapshot a plan as a baseline and compare it against the live schedule to see exactly where things moved.
Comments, attachments & activity
Discuss work directly on a task, attach files up to 25MB, and see a full audit trail for the project.
Live-updating collaboration
See what teammates are working on as they work. Selection and changes refresh automatically every few seconds.
Shareable read-only links
Send a link to stakeholders who need visibility without needing an account.
Organizations, roles & audit log
Invite teammates, assign roles, and review a full change history, down to before/after field values.
Undo/redo & flexible export
Full undo/redo history, plus export to CSV, Excel, JSON, PNG, and PDF, including a shareable chart snapshot.
Local-first with cloud sync
Work offline against a local database, then sync to the cloud when you are back online.
Where GanttPM runs today
Web app
Fully functional, including cloud sync and live collaboration. This is the recommended way to use GanttPM with a team today.
Desktop & mobile
Same UI, currently best for local/offline use. Cloud sync and sign-in on these platforms are still being finished.
