MermaidCreator vs Mermaid Live Editor

Both render Mermaid free in your browser. The difference is what happens when you need to do more than render: edit visually, generate with AI, save, and share.

Mermaid Live Editor (mermaid.live) is the official Mermaid playground, and it's genuinely good — instant, free, and always up to date with the latest Mermaid release. MermaidCreatoruses the same Mermaid syntax but wraps it in a full editor: a drag-and-drop canvas that writes the code for you, Claude-powered AI that drafts and repairs diagrams, cloud saves with version history, and hosted share links. Here's the honest breakdown.

Frequently asked questions

Is MermaidCreator an alternative to Mermaid Live Editor?
Yes. Both are free in-browser Mermaid editors with a live preview. Mermaid Live Editor (mermaid.live) is the official playground and is excellent for quick one-off renders; MermaidCreator adds a visual drag-and-drop canvas, AI generation and repair, cloud-saved diagrams with version history, hosted share links, and a template gallery on top of the same Mermaid syntax.
Can I move my diagrams from mermaid.live to MermaidCreator?
Yes — a Mermaid diagram is just text. Copy the code from Mermaid Live Editor, paste it into the MermaidCreator editor (or the free converter tools), and keep working. Nothing is locked in either direction.
Is MermaidCreator free?
Yes. The visual and code editors, live preview, PNG/SVG export, share links, and up to 10 saved diagrams are free, including 5 AI generations per month. Pro ($9/month) adds unlimited AI generations, unlimited diagrams, full version history, and PDF export.
When is Mermaid Live Editor the better choice?
When you just need to render a snippet once and move on, mermaid.live is perfect — it's the official tool, always current with the newest Mermaid release, with zero product around it. MermaidCreator earns its place when you edit diagrams repeatedly, want AI to draft them, or need to save and share them.
