Gitlab is using Monaco for this. An open sourced online editor brought to you by none other than Microsoft. (https://github.com/Microsoft/monaco-editor) I couldn't dig it up now but I recall seeing that Microsoft started this project as an online code editor for Azure, later using it in VSCode. So it would not be surprising if they bring this to github some time in the future.

I'm well aware of monaco.

I doubt something like what gitlab is building will come to github. Maybe a quick edit editor, but nothing more.

Gitlab is going to integrate this to gitlab's CICD infra.

If github gets one, it'll be a shitty typo fixer, that's it.

It still is "alive" somewhere in Azure but MS scrapped it really and focused making the best possible Desktop Editor. You wont see a web editor form them soon.
