We built Diagram Lens because Mermaid diagrams in Confluence are great right up until an architecture map or workflow grows past the width of the page then you're stuck scrolling sideways or exporting to another tool just to read your own documentation. Diagram Lens keeps the Mermaid source editable right inside Confluence and adds a proper reader for the big stuff: pan/zoom/fit controls, in-diagram search with highlighting, and a minimap so you never lose your place in a sprawling diagram. When you need to hand a diagram off, you can export the source, sanitized SVG, or (best-effort) PNG/PDF straight from the page. A few things we cared about for this launch: No external diagram account to manage everything renders client-side inside Forge Custom UI No vendor-hosted backend, no external analytics, no AI service, no remote Mermaid renderer the current manifest declares no external egress Diagram config lives in Atlassian's own Forge hosted storage. It's free, and it's intentionally scoped: this is a source-first diagram reader/editor, not a drag-and-drop diagramming tool or an AI diagram generator. Would love to hear from anyone who lives in Confluence docs especially if you've got a diagram that's outgrown its page. What's missing for your workflow?
