I’ve been using Mermaid for diagrams — flowcharts, sequence diagrams, and system design.
But most editors I tried had a few problems:
cluttered UI
slow live preview
or requiring login for basic usage
So I decided to build a small tool for myself — something simple and fast.
🚀 What I built
It’s called Marmady — a minimal Mermaid live editor focused on speed and usability.
✨ Features
⚡ Live preview while typing
📤 Export as SVG / PNG / PDF
🎨 Clean, distraction-free UI
🔓 No login required
The idea was to remove friction and make diagramming feel instant.
🧠 What I focused on
Instead of adding more features, I focused on:
performance
simplicity
clean design
I wanted it to open fast and just work.
🛠️ Challenges
A few things were tricky while building:
keeping live preview fast
handling export formats properly
maintaining UI simplicity without limiting usability
📈 What’s next
I’m still improving it and adding features based on feedback.
Some ideas:
more themes
better diagram templates
keyboard shortcuts
🙌 Feedback welcome
If you use Mermaid or create diagrams often, I’d love to hear your thoughts.
What’s the most annoying part of your current workflow?
