WASM Tool to Convert Mermaid to ASCII
Simon Willison · rss · 2026-07-16
The author has compiled a Mermaid to ASCII conversion tool into a WebAssembly version that runs directly in the browser, making it easier to compare different implementations.
They initially built the Mermaid-to-ASCII tool based on Rust code from Grok Build. Later, discovering a more mature Go version (AlexanderGrooff/mermaid-ascii), they used Claude Fable 5 to compile it into WASM as well.
This newer version also includes support for color rendering.
