Godot web (ik it's a bad idea)

some of my friends that are helping me with a game, can’t open the editor, but for some reason they can’t use the “mobile” option when opening a new project in godot web, and another thing, is it possible to use git with godot web?

It may be that they are using a computer without a gpu that does not support vulkan as godot likes. They might be able to use command line argument --rendering-device opengl3 or the 4.4 dev3 build to automatically fallback to opengl.

The web editor, and web-exported games only support the compatibility (opengl) renderer. It might be possible to use git in the web editor through some wasm/javascript version of git, but it sounds extremely cumbersome.
