Versatile Mermaid Renderer for Jira

What does this do?

It allows you to use the Mermaid Markdown syntax to create technical diagrams directly in your Jira issues. The app adds a panel to Jira issues that is easily shown and hidden by a button at the top of the page.

Adding Diagrams to your Jira issues

Once your Jira administrator has installed the app it will place a “Mermaid Diagrams” button on the issue toolbar. Clicking that button shows the Mermaid Diagrams panel and you can add diagrams by clicking the “Add Diagram” button.

Read on to discover all the options available…


Enter Mermaid Markdown into the editor

And have it create an image in your issue. The editor looks like this and allows you to preview what the image will look like.

The app generates fully scalable SVG images.


Specify a URL

You can alternatively specify a link to some Mermaid Markdown via a URL. This could be to Github, Bitbucket, or anywhere else on the internet as long as it is a publicly accessible URL (NB: If using a code repository like Github, ensure you provide the link to the raw content).


Start with a template

Use one of the supplied templates to generate your diagrams. It’s always easier to start with a structure already in place and then edit it so we make that easy for you!

The common diagram types are covered:

  • Activity Diagram
  • Sequence Diagram
  • Class Diagram
  • and more – see the screenshot

Manage your diagrams

There’s a little menu to manage each diagram – click the 3 dots in the top right of each diagram’s display.

This allows you to:

  • Move the diagram up or down (if you’ve added more than one diagram to the Jira issue)
  • View it in a fully zoomable popup
  • Edit the diagram
  • Remove the diagram
