One path determines the date. FlexiGantt makes that path visible.

Milestones as first-class citizens in the plan

  • Define the milestones you commit to
  • See what contributes to each milestone date
  • Protect each milestone with a buffer
  • See how much delay you can afford

Plan against the consequence

When the plan changes, the answer changes with it

  1. Record the commitment as a baseline
  2. Run the project in weekly iterations and track actual dates
  3. Monitor commitments and milestones: forecast, remaining buffer, and status against the baseline
FlexiGantt Milestones view: a table compares each milestone's forecast with the baseline (UAT Completed, Release Readiness Gate, and Beta Release are 7 days late; Go Live is 1 day late), and a Fever chart below plots buffer consumed against work complete, with the late milestones in the red zone and Go Live in the green zone after its deadline moved and it gained 10 days of buffer
Three milestones slipped 7 days against the baseline. The Fever chart puts them in the red zone: buffer is going faster than the work. Go Live stays green because its deadline moved and gained 10 days of buffer.

From schedule to steering deck

Report from the plan you work in

  1. Switch to the Roadmap view
  2. Select the phases and milestones your audience needs
  3. Export the slide as editable PowerPoint: native shapes that take your deck’s template

Or ask your AI assistant to export the roadmap through the local MCP server.

FlexiGantt Roadmap view: the Roadmap items panel shows 12 of 22 items, with workstream summaries and milestones checked and detail tasks unchecked; the slide shows only the checked items: the workstreams, UAT Testing, Beta testing, and the UAT Completed, Release Readiness Gate, Beta Release, and Go Live milestones
Uncheck the detail. The slide keeps the workstreams and milestones the steering committee asks about.

Built for delivery planning

Answer the question behind the date

Critical path and float

See the chain of work determining your finish date—and how long other tasks can move without delaying it.

Deadline buffer

See how many working days remain before each committed milestone is at risk, and watch that margin change as the schedule moves.

Dependency gates

Model approvals, vendor deliveries, environment readiness, and other gates that depend on several prerequisites. See which prerequisite is holding each gate back.

Stale forecasts, flagged

When progress has not been updated, affected tasks are marked stale. The warning carries through to every milestone that depends on them, so an outdated forecast cannot look healthy.

Change log and undo

Every edit is recorded in plain language. Review what changed and undo any edit when you need to.

Editable PowerPoint export

Export the schedule as an editable roadmap slide. Apply your company template, adjust the layout, and present it without rebuilding the plan in PowerPoint.

Local MCP integration

Connect a compatible MCP client to FlexiGantt locally to inspect schedules, trace dependencies, analyze milestone dates, and export results.

For the people carrying the commitment

Make the next status update precise

Delivery or Engineering Lead

Coordinates a launch across several teams, vendors, or workstreams and needs a reliable answer when someone asks, “If this slips by a week, does Go Live move?”

Independent Project Manager

Runs delivery across clients and needs a portable project plan that works offline and does not depend on access to client systems.

Program or Workstream Lead

Coordinates major activities and dependencies across a program or workstream and needs to see how changes affect committed milestones and the overall Go Live date.

Plan the date. See the path.
