Key highlights of the appMermaid diagrams on any Jira issue — 26 diagram types, live preview, and one-click templates

26 Diagram Types, One Panel

From flowcharts and sequence diagrams to C4 architecture, Gantt charts, and Kanban boards — every diagram type you need is one click away via the Quick Templates panel.

Live Preview as You Type

The fullscreen editor renders your diagram in real time. Adjust code, switch themes, or tweak colors and see the result immediately — no save required to preview your changes.

Diagrams Stored on the Issue

Each diagram is saved directly to the Jira issue and loads instantly for every viewer. Dark mode is handled automatically, so diagrams always look right regardless of the user's Jira theme.

More details

Mermaid+ Diagrams brings visual communication into your Jira workflow. Open the issue panel, click Create Diagram, and a fullscreen editor appears with a live preview on the left, 26 quick-start templates in the middle, and a code editor with settings on the right. Every keystroke updates the preview instantly.

Choose from flowcharts, sequence diagrams, Gantt charts, state machines, ER diagrams, C4 architecture, Kanban boards, mindmaps, and 18 more types. Customize node colors, border colors, fonts, and themes to match your team's style. Diagrams load instantly on the issue — the editor is only loaded when you need changes.

Diagrams are stored on the issue and visible to anyone who can view it. Only users with Edit Issues permission can create or modify them. Dark mode is fully supported — diagrams adapt automatically when Jira's theme changes.

Ideal for engineering teams, architects, and project managers who need to communicate complex ideas visually without leaving Jira.
