I’ve been using GoTTY (https://github.com/yudai/gotty) to do the same thing, combined with ngrok or Cloudflare tunnels to get a publically accessible URL. To enable multiplayer mode, just need screen/tmux.
Nice trick! Many people have mentioned that tmux lets you share terminals, though worth noting that it takes a bit of setup, doesn’t render correctly when you have different screen sizes, and requires stitching together a lot of other tools to work over a browser.
Personally I think being able to arrange and resize terminals adds a lot to the collaboration feeling, as well as seeing people’s cursors. I encourage you to give it a try! (it takes less than a second to install, and then you just run “sshx”)
