Mermaid Chart for Confluence

The generated diagrams are tiny and blurry, and therefore useless. I can not get the app to work in Firefox.

The diagram stored and previewed is not really visible nor deemed useable if its a slighly complicated diagram, even with Extra Large bring selected.

I agree with other reviewers that this tool is merely "okay". The UI itself is fine, but it only stores very small PNG images that simply aren't readable for all but the simplest of diagrams. This would be completely fixed if they stored diagrams as SVGs, or at least as larger PNGs. The "extra large" size is still ~800x600px -- way too small. Update: Changed score from 3/5 to 1/5. We installed this app when it offered "offline" diagram support -- no login required. The maintainers then performed a "bait-and-switch". They updated the app to require a login, effectively preventing us from using this app. It is now useless, and we need to replace our existing usage with alternatives. Judging by this behavior, it wouldn't surprise me if they eventually drop their free tier for Mermaid accounts.

Is it correct that it is not possible to view a diagram i full screen view what it is integreated on a page?

It now renders diagrams without cloud subscription so that's nice, but any larger graphs unreadable as it doesn't use full width of the page.
