More details

Diagram Lens - Mermaid charts for Confluence helps teams keep architecture, process, and system diagrams close to the Confluence pages where decisions happen.

Paste Mermaid source, preview it live, save it as a Confluence macro, and inspect large diagrams with tools designed for real documentation work: wide view, pan and zoom, fit/reset controls, in-diagram search, minimap navigation, layout presets, dark mode, and export options.

Diagram Lens is built for teams that prefer text-based diagrams but need a better reading experience than a plain code block or static image.

Release date: Jul 9th 2026
Summary: Free Confluence macro for Mermaid editing, search, navigation, and export.

PNG, PDF, and clipboard export are best effort and may depend on browser support, Forge iframe permissions, and diagram size. SVG export is the primary reliable diagram export path.
