I feel comfortable with web technologies, and a large part of this project was using Monaco Editor as a powerful diff viewer, so I'll stay with my current stack. I'd be happy to make a pure web app, but I don't think it's possible with something like a Git client, since it needs to call system commands. Maybe there are some hacks available for local apps, but why would that be better than just using Electron. Yeah, it takes some space, but what is this compared to, for example, any modern computer game.
