Key highlights of the appWrite Mermaid, get a rendered diagram in Confluence

Write diagrams as code inside Confluence

A live editor with syntax highlighting, starter templates, and a preview that updates as you type. Supports every major Mermaid diagram type.

Private by design

No scopes, no external network, no backend. Drop in a .mmd or Markdown file and it's read in your browser and it is never opened or uploaded anywhere.

Interactive on every page

Readers get a crisp, theme-matched diagram with pan, zoom, fullscreen, and one-click SVG/PNG export plus the exact Mermaid version rendered.

More details

Merfluence renders Mermaid diagrams on any Confluence page entirely in your browser. Type /mermaid, write a diagram as code, and get a clean, themeable SVG.

See it live. Every diagram type, rendered for real, no login needed: Merfluence demo space

Private by design. No backend, no data-access permissions. Diagram source lives in the page and renders in the reader's browser. Nothing is sent to us or anyone else.

Built for authors. A live editor with Confluence-themed syntax highlighting, 18 starter templates, inline errors, and a pan/zoom preview. Drag in a .mmd or Markdown file, or paste a Mermaid.Live Editor link. Export as SVG or PNG, with or without a background.

Accessible. Full keyboard pan, zoom, and fullscreen; every diagram carries a text alternative for screen readers. Accessibility statement and VPAT published.

Fast and stable. Diagrams are cached in the macro and render lazily as they scroll into view; pin a Mermaid major per diagram so upgrades never break it.

Version information

Version 2.42.0•for Confluence Cloud

Release date: Aug 13th 2026
Summary: Mermaid syntax highlighting, PNG background choice, and better diagram sizing
Details: New
• Syntax highlighting in the editor — Mermaid source is colored by diagram type, using Confluence design tokens so it reads well in light and dark mode.
• Choose your PNG background — export with the page background, or fully transparent to composite onto a surface you control.
• Exports are named after the diagram and when you saved them (deploy-pipeline-20260808-143205.png), so downloads sort by date instead of piling up as "diagram (2).png".
Fixed
• Wide diagrams, and their PNG exports, now size from the diagram itself rather than the column, so they are no longer squeezed to a default width.
• Mindmap labels are centered inside their nodes.
• Keep full width applies instantly, with no re-render.
• SVG exports carry the diagram's real dimensions, so other tools open them at the right size.
• The zoom buttons name the Ctrl/⌘ + scroll shortcut.
