Diagrams re-render instantly when readers switch Confluence themes. No white boxes on dark pages — ever.
Large diagrams are actually readable: zoom controls, one-click fullscreen, and retina-quality PNG/SVG export.
See your diagram update as you type, with starter templates for the six most-used diagram types.
Coming from the legacy Stratus mermaid app? Our built-in tool scans your site and converts every diagram automatically.
Diagram source is stored inside your pages — in your exports, history and copies. Uninstall us and it's still there.
Rendering happens entirely inside Atlassian's infrastructure. No external servers ever see your diagrams.
