Mermaid Diagrams for Jira

Mermaid diagrams on every Jira issue: paste Mermaid or use the live editor, in your own colours

Draw Mermaid diagrams right on your Jira issues. Any mermaid code block in the description or a comment is drawn automatically, and a live editor lets anyone who can edit the issue add flowcharts, sequence diagrams, state machines and more. Diagrams are stored on the issue itself, so nothing leaves Atlassian.
