Why selected
Clever architecture (Go+WASM), high practical value for terminal/plain-text scenarios, and from reputable blogger Simon Willison.
AI commentary
「If you need to embed flowcharts in plain text or a terminal, this tool is a perfect pick. It reminds me of early ASCII UI days, but now with modern WebAssembly making it happen offline in the browser. Definitely worth a try for developers who love simplicity and low dependencies.」
Quick overview
Simon Willison released an open-source tool, mermaid-ascii, that converts Mermaid diagram syntax into ASCII and Unicode box-drawing art entirely in the browser via a Go library compiled to WebAssembly. It supports flowcharts with labeled edges, subgraphs, and is ideal for embedding diagrams in plain-text contexts or terminals.
- Client-side rendering via Go-compiled WebAssembly
- Supports flowcharts, subgraphs, labeled edges
- Outputs pure ASCII and Unicode box-drawing art
- No backend or network requests; works offline

Tool: Mermaid to ASCII art (mermaid-ascii)
After building the Mermaid to ASCII tool based on Grok Build's Rust code I learned that there's an older, more fully-featured Go library called AlexanderGrooff/mermaid-ascii that implements a similar pattern, so I had Claude Fable 5 compile that one to WebAssembly as well so I could compare the two.
This one includes support for colors!
