Key highlights of the appMermaid diagrams on any Jira issue — 26 diagram types, live preview, and one-click templates
26 Diagram Types, One Panel
From flowcharts and sequence diagrams to C4 architecture, Gantt charts, and Kanban boards — every diagram type you need is one click away via the Quick Templates panel.
UML & Architecture Diagrams
The fullscreen editor renders your diagram in real time. Adjust code, switch themes, or tweak colors and see the result immediately — no save required to preview your changes.
Gantt Charts & Live Preview
Each diagram is saved directly to the Jira issue and loads instantly for every viewer. Dark mode is handled automatically, so diagrams always look right regardless of the user's Jira theme.
