It's been brought to my attention that it works, so I thought I'd share:

A web version of VSCode integrated with github works in Wayfarer (with some caveats). To run, sign in into github, go to your favourite repository and press . (dot). This will forward you to fe https://github.dev/jacadcaps/gamepadlib.

Hint: for editing to work, you need to use a Safari user agent.

I tried VScode web with previous versions of wayfarer and it worked.

Vscode is a great editor but is slow in my 2ghz g5.
I imagine is all those js running in the background.

Anyway, its great that wayfarer has the compability level to can run vscode.
