Reliable Mermaid diagrams for Confluence

Better Diagrams saves the rendered diagram alongside its source so readers see the artifact the author saved—even when live rendering would be unreliable.

The user problem

Why this exists

Technical documentation loses trust when a saved diagram disappears, changes unexpectedly, or cannot be recovered or exported reliably.

Mermaid diagrams missing or changing after publication
Diagram source becoming difficult to recover
Unreliable PDF and Word exports
Recovering earlier saved revisions
Dependence on remote rendering services

Evidence and testing

Tested on a real Confluence Cloud site. PDF and Word exports were verified by inspecting the downloaded files, not merely checking that a download occurred.

Engineering coverage: the implemented product covers 18 of 20 validated complaints inside its declared product boundary. This measures implemented acceptance coverage—not demand, revenue, adoption, or willingness to pay.

Privacy and security

Diagram rendering is performed locally without sending Mermaid source to a remote rendering service.

The saved source and artifact remain within the Confluence product boundary. Marketplace disclosure and Atlassian platform controls govern installation and data access.
