Wezterm terminal supports multiplexing from the box: https://wezfurlong.org/wezterm/multiplexing.HTML

Also, there is Hyper terminal, and standalone protocol to implement multiplexing https://www.reddit.com/r/commandline/comments/q5mj11/htm_a_c...

If you know other options, please share.

I work in windows, but at home I use macos, so I stick to wezterm. I use it with single config for both platforms (config is written in Lua)
