Atlassian Mermaid Viewer is a Chrome extension designed to enhance the visualization of Mermaid diagrams in Confluence and Jira. By automatically detecting Mermaid syntax, it transforms raw code blocks into interactive SVG diagrams, eliminating the need for manual rendering or external tools. Users can seamlessly navigate between pages without losing diagram integrity, thanks to its support for Confluence’s single-page application architecture. The extension provides quick actions for users to open diagrams in the Mermaid Live Editor or copy the source code with ease.

Supporting a wide variety of diagram types such as flowcharts, sequence diagrams, and Gantt charts, the extension ensures that node labels and diagram sizes are rendered correctly, addressing common CSS conflicts in Confluence. It operates entirely within the browser, safeguarding user privacy by not transmitting any data to external servers. This tool is particularly beneficial for software engineers and technical writers who frequently document complex workflows and architectures.
