CloudScript Mermaid Diagrams for Confluence

Mermaid diagrams as a Confluence macro: write the diagram as text, and the page renders it. Flowcharts, sequence, class, ER, state, Gantt and swimlane diagrams are all supported, with Mermaid 12 as the default engine and Mermaid 11 still available.

Every macro pins its own Mermaid version. Diagrams saved before an engine update keep rendering exactly as they did; new diagrams start on the latest version, and you move older ones across one at a time when you choose.

Each diagram can set its theme (Neo, Redux, Mermaid's built-ins and their dark variants), look (Classic, Hand-drawn or Neo) and layout engine (Mermaid's default or ELK, for dense flowcharts) from the macro editor or in front matter.

The app is built on Forge and is badged Runs on Atlassian: diagram source and rendering stay inside your Confluence site, with no external servers and a single read scope. Diagrams render for anonymous and unlicensed viewers, so public documentation keeps working.
