What it does
Mermaid Diagrams adds text-based diagram creation to Confluence using Mermaid.js notation. It supports flowcharts, sequence and class diagrams, entity-relationship and state diagrams, Gantt charts, pie charts, and user journeys. A live rendering appears before saving and reports parsing errors. The app provides starting examples, follows Confluence's light and dark themes, and renders in the browser without sending diagram data to a third-party server.
