I've set up an online demo using Wasmer for local execution, so everyone can try easily! (try typing `cowsay hello`):

https://ghostty-web.wasmer.app/

How to try it locally:

  npx @ghostty-web/demo@next # The preferred way
  # OR 
  wasmer run wasmer/ghostty-web

  -> Go to http://localhost:8080/

Source code: https://github.com/wasmerio/webassembly.sh (updated from xterm into ghostty-web without any issue!)
