Excalidraw Nomnoml Diagrams for Jira

Combine freeform Excalidraw whiteboards with Nomnoml UML diagrams directly inside Jira issues, project pages, and global pages. Type Nomnoml's lightweight text syntax and the rendered diagram drops straight onto your Excalidraw canvas — no manual shape-dragging required — then sketch around it with Excalidraw's normal hand-drawn tools.

Save a whiteboard as a scene once, globally or scoped to a project, and attach that same scene to any issue so diagrams stay consistent across your team instead of being rebuilt each time. Built-in Excalidraw shape libraries are bundled with the app itself, so browsing them makes no external API calls.

Canvas data, attached scenes, and diagram content are all stored using Atlassian Forge's own storage APIs, so nothing leaves your Jira instance. Note: editing is one person at a time per scene (save/load), not live multi-user co-editing.
