Is this Mermaid editor completely free?

Do I need an account or to install anything?

No. Open the page and start editing. It works on desktop and modern mobile browsers.

Which Mermaid diagram types are supported?

All core types: flowchart, sequenceDiagram, classDiagram, erDiagram, gantt, mindmap, pie, state, gitGraph, and more. The editor uses the latest Mermaid renderer.

Can I use diagrams I make here in my own documentation?

Absolutely. Export SVG or PNG and drop them into READMEs, Notion, Confluence, Google Docs, or any Markdown file.

How do shareable links work?

The entire diagram is encoded in the URL query parameter. Bookmark it, email it, or paste it anywhere. No server storage involved.

How is this different from mermaid.live?

This editor is lightweight, focused, and built by the Moxie Docs team. It emphasizes fast exports, clean URLs, and privacy with zero tracking on the tool itself. Great when you want something simple and embeddable in a dev workflow.
