MS Project Gantt Is Dead — What Now?

For years, “Gantt chart” and “Microsoft Project” were almost interchangeable.

The workflow is simple: create tasks, connect dependencies, check the critical path, assign resources, and export the plan for the next meeting.

Not anymore.....

Microsoft retired Project for the web and moved its capabilities into Microsoft Planner. Project Online is also scheduled to retire on September 30, 2026.

To be honest: the Microsoft Project desktop app is not disappearing. But Microsoft’s cloud project-management strategy is shifting to Planner—and that gives product teams a reason to reconsider where scheduling should live.

The Gantt is moving into the product

Multiple of our customers still ask the same questions:

• When should work start and finish?


• Which task is blocking another?


• What happens if a task slips?


• Which deadline is at risk?


• Who is overallocated?

And they expect those answers inside the software they already use: an ERP, construction platform, manufacturing system, product-roadmap tool, logistics application, or internal operations dashboard.

For these products, sending users to a separate planning tool creates friction and splits the source of truth. The better option may be to embed planning directly into the application.

A real Gantt is more than task bars?

Drawing a colored bar on a timeline is easy. Building a schedule users can trust is much harder.

If Task B depends on Task A, the system needs to calculate what happens when Task A moves. If a task can only start after a permit date, the constraint must be respected. If a resource is assigned to two tasks at once, the system should report the conflict—or resolve it predictably.

A serious scheduling component therefore needs more than drag and drop. At minimum, look for:

• task hierarchy and summary rows;


• milestones;


• dependencies with lead and lag;


• working calendars and holidays;


• constraints and deadlines;


• manual and automatic scheduling;


• resource allocation;


• critical path and slack;


• clear diagnostics when rules conflict.

The last point matters. Silent date changes quickly destroy trust. Users need to understand not only that a task moved, but why it moved.

Don’t lose the table

Our business applications do not start as Gantt charts. They start as tables.

Those contain custom columns, editors, validation, permissions, filters, keyboard workflows, status badges, and business-specific data. We could just use another model and component to build Gantt but....

A better approach is simple:

Keep the table. Add scheduling intelligence and a timeline on top.

That is the idea behind RevoGrid Gantt. The existing data grid handles the table experience—rendering, virtualization, editing, selection, and keyboard interaction. The Gantt layer adds task bars, dependencies, calendars, resources, baselines, critical path, and scheduling rules.

Users can work with familiar rows and columns while gaining a visual project plan. Developers keep control of their data model instead of rebuilding the workflow around a standalone project-management tool.

What should you do now?

Before choosing a replacement for Microsoft Project, start with your actual workflow:

1. List the scheduling concepts your users depend on: tasks, dependencies, calendars, resources, baselines, constraints, actuals, and custom fields.


2. Decide where the source of truth should live—your backend, an ERP, Dataverse, or another system.


3. Preserve the existing table experience, including editors, validation, permissions, and keyboard behavior.


4. Treat scheduling conflicts as part of the product UX, not as hidden engine errors.


5. Introduce complexity gradually: tasks first, then dependencies, calendars, critical path, and resource planning.

The Gantt is not dead. The silo is.

Microsoft Project shaped how a generation thinks about project scheduling. But the future of Gantt is not limited to standalone planning software.

Some teams will move to Planner. Others will choose a complete Gantt suite. And many product teams will bring scheduling into the applications where work already happens.

For that last group, the direction is clear:

Keep the grid. Add the timeline. Preserve the context.
