Excalidraw Mermaid Diagrams for Jira

Excalidraw Mermaid Diagrams for Jira embeds a full Excalidraw whiteboard directly into Jira issues, project pages, and a dedicated global page for your whole site. Sketch flowcharts, architecture diagrams, and freehand notes using Excalidraw's hand-drawn style — shapes, arrows, freehand drawing, shape libraries, dark mode, zoom, pan, and undo/redo.

Alongside your sketches, write Mermaid syntax to generate flowcharts and diagrams in the same scene, rendered locally in your browser with no external Mermaid service call. Save a diagram as a scene and attach that same scene to any number of Jira issues or projects, so you build a diagram once and reuse it everywhere it applies.

The global page gives everyone on the instance one place to browse and manage every saved scene. Diagrams and scenes are stored using Atlassian Forge storage — nothing is sent to an external server, and no separate diagramming account or tool is required.
