How to show a critical path in Jira (free)
Jira does not ship a critical path. The built-in board and Basic Roadmap show issues and a loose timeline, but neither calculates the critical path — the chain of tasks where any slip pushes your deadline. The good news: you can add it to Jira Cloud for free in a couple of minutes. Here's how, and how to actually use it.
What the critical path is (and why it matters)
The critical path is the longest sequence of dependent tasks through your project. Its length sets your earliest possible finish date. Tasks on the critical path have zero slack: if one runs late, the whole project runs late. Tasks off the critical path have float — they can slip a little without moving the deadline. Knowing which is which tells you exactly where to focus when things get tight. This is the classic Critical Path Method (CPM), the same idea behind MS Project and Primavera.
Why Jira doesn't have it natively
Jira is built around the agile board, where commitments live at the sprint level rather than on a dependency-linked timeline. A critical path needs dated tasks with dependencies between them — a Gantt model Jira doesn't provide out of the box. That's why critical path lives in Marketplace Gantt apps.
How to add a critical path to Jira (step by step)
- Install a free Gantt app with CPM. Open the GanttBoard listing and click Get it now (you need Jira admin). It's a Forge app, so nothing leaves your tenant.
- Open a project → the GanttBoard tab. Issues with start and due dates appear on the timeline immediately.
- Link your tasks. Hover a bar, grab one of the two dots, and drag to a dot on another bar to create a dependency. All four types (FS, SS, FF, SF) are supported, with lag.
- Turn on Critical path. Click the Critical path button in the toolbar. GanttBoard highlights the longest dependency chain automatically.
How to read it
Once it's on, the highlighted bars are your schedule-critical work — protect those dates first. If you want to know how a slip ripples through the plan, use auto-scheduling to cascade dates along the dependencies. And to track whether you're drifting from the original plan, save a baseline and compare. For the full walkthrough see the critical path feature page, or our 2-minute Gantt setup guide.
The short version
Jira has no critical path on its own, but adding one is free and fast: install a Forge Gantt app, link your tasks, and toggle the critical path. Five minutes from "I wish Jira showed this" to "I can see exactly what's protecting my deadline."
