Key highlights of the appAuto-render Mermaid diagrams in Jira issues and comments - flowcharts, sequence diagrams, ERDs and 20+ more
Auto-render
Paste a Mermaid code block into any issue description or comment. Diagrams appear in the issue's Mermaid Diagrams section automatically, with a count badge, and refresh when you save.
Full-screen view + dark mode
Open any diagram full-screen with zoom and pan to read every detail, plus one-click copy or download as SVG or PNG. Dark or light mode for the images follow your chosen Jira theme.
Eleven diagram styles
Eleven designed styles — clean, hand-drawn, blueprint, chalkboard and more — each with bundled fonts, each covering every diagram type. Switch per diagram, or lock a style into the source.
More details
Mermaid Diagrams brings diagrams-as-code to Jira.
Add a Mermaid code block to any issue description or comment and it auto-renders as an interactive diagram — no setup, no manual triggers.
Works with Rovo: ask Rovo to draft a diagram, paste the code block, and it renders.
Open any diagram full-screen with zoom and pan, export it as SVG or PNG with the diagram's font embedded, or scan a QR code to open it on your phone.
Supports flowcharts, sequence/class/state diagrams (UML), ERDs, Gantt, pie charts, git graphs, mindmaps, kanban, architecture, treemap, sankey, radar and more — every diagram type in Mermaid 11.16. V4, an optional styling upgrade, adds designed styles with bundled fonts, right-angle connectors, and copy style as code.
Version 3 remains free forever; updating to v4 starts a subscription — $0 for teams of 10 or under. Runs on Atlassian: 100% client-side, read-only permissions, no external calls, no analytics; SOC 2 Type II and GDPR inherited from Forge.
