MD-VisMD-Vis vs Mermaid Live Editor
These tools solve different problems. The Mermaid Live Editor is the best place to craft a single diagram; MD-Vis is for whole documents that happen to contain diagrams.
The Mermaid Live Editor is the official playground for Mermaid: paste diagram code, tweak the theme and configuration, and export the diagram as SVG or PNG. It is excellent for perfecting one diagram. MD-Vis is a full Markdown editor — text, tables, code and multiple diagrams (Mermaid and Excalidraw) — that exports the entire document to PDF, Word, PowerPoint or PNG.

When the Mermaid Live Editor is the better choice
- You only need to build or fine-tune a single Mermaid diagram.
- You want fine-grained Mermaid theme/config controls and an export to SVG.
- You want a shareable link to that specific diagram.
When MD-Vis is the better choice
- You are writing a document — notes, a report, a spec — that includes one or more diagrams.
- You need to export the whole thing to PDF, Word or PowerPoint.
- You want Excalidraw whiteboards in the same document.
The two pair well: design a diagram in the Mermaid Live Editor if you need its controls, then drop the Mermaid code into MD-Vis to assemble and export the full document. See the Mermaid flowchart syntax guide to get started.
