Diagram Apps for Jira — Which Diagramming Tool Should Your Team Use?
· 7 min read
Every engineering team needs diagrams in Jira — architecture decisions on epics, bug reproduction flows on tickets, wireframes on stories. But Jira has no built-in diagramming. You either paste screenshots from external tools or install a marketplace app.
We built two diagram apps for Jira: Mermaid+ Diagrams for Jira for text-based diagrams using Mermaid syntax (flowcharts, sequence diagrams, ER models, C4 architecture), and Excalidraw Diagrams + Whiteboards for Jira for freeform drawing with 229 built-in shape libraries. In this post we compare both against every alternative on the Atlassian Marketplace.
