Have you had much success with VS Code's multiplayer extensions? I've found them buggy to the point of useless, but maybe things have improved. Zed, on the otherhand, is developed by people who understand pair programming, which is my priority.
No not much experience there since multiplayer editing has never really been a part of my personal workflow (mostly a lot of screensharing), but I can definitely see that being useful for people that use it regularly.
Not the OP but I tried hard, looking for an easy pair programming solution. Worked decently a couple of times and inexplicably failed most of the time.
This is why I'm excited to try Zed. I regularly "pair" via Pop, but keybindings and lag make it hard to switch seats, so we basically decide at the beginning of the session who is going to hog the keyboard, and that's a crippling dynamic.
