Show HN: GUI for editing Mermaid class diagrams

Nice! I love how mermaid keeps getting better!

For sequence-diagrams, nothing beats https://sequencediagram.org/ (I am not connected with them in any way, just a happy user)

Yes! You can use this in the free mermaid playground: https://www.mermaidchart.com/play

That's pretty cool. Wish PlantUML community would have something like it.

Thanks, I uploaded it!

I spent some time playing around with this recently and loved it at first. I also realized ChatGPT is pretty good at generating Mermaid diagrams (didn't try your own AI features).

However after getting into it some I ran into some significant frustrations. After creating a medium-complexity diagram, I was excited to see the Whiteboard feature to drag things around / improve the layout manually. But it really started breaking, it just wouldn't let me organize/drag things where I wanted, and I couldn't get things to not overlap. I also wished more diagram types supported Whiteboard (I noticed some didn't).

Also I some confusion between the capabilities of mermaidchart.com and mermaid.live. Are these competitors? Variations of similar apps. I was confused. Also "Playground" vs "Live Editor" is confusing.

Overall glad this exists and hope it continues to improve.
