Mermaid Diagram for Confluence
Mermaid diagrams in Confluence, with a live preview, templates, page trees and your own colour themes
Write Mermaid and see the diagram as you type: flowcharts, sequence, class, state, ER, Gantt, mind maps and more. Map a Confluence page tree in one click, link any box to a page, and style every diagram with your own colour themes, in light and dark mode. Everything runs on Atlassian Forge, so your diagrams never leave Atlassian.

Usage and search
Admins see every page that contains a diagram, and Confluence search finds diagrams by their text
What changes for your team
- Keep diagrams as text next to the docs they explain, so anyone can edit them without a drawing tool
- See the diagram as you type, and start from one of 12 templates instead of a blank page
- Map a section of your Confluence space as a diagram, where every box opens its page
- Turn any box in a flowchart into a link to a Confluence page with a right-click
- Give every diagram on the site your brand colours, with a matching dark-mode version
- Keep everything inside Atlassian: the app runs on Forge and sends nothing to Yamuno
