What it does
Merfluence adds a /mermaid macro for writing Mermaid diagram code on Confluence pages. Its editor includes highlighting, templates, error messages, and a preview with pan and zoom controls. It accepts .mmd files, Markdown files, and Mermaid.Live Editor links, then can export diagrams as SVG or PNG. Rendering takes place in the browser, and the diagram source remains in the Confluence page.
