I also hate how tmux uses alt mode and can never remember all the shortcuts, copy paste is a PITA and just today I had to look up how to dump the scrollback buffer to a file. Named sessions without window management makes a lot more sense these days. Similarly, I'm not a fan of all the ANSI escape codes that CC uses to jump the cursor around and rewrite the display to look like a GUI. I prefer a TUI that doesn't mutate rows after writing them, that's what alt mode is for. CC often clears whatever was in the scrollback buffer before you opened it, it hides bracketed paste, and goes crazy sometimes when content overflows the window and I have to resize the terminal or get blasted with a wall of glitching characters--extra annoying if I'm working from a low bandwidth link. I develop my own agent framework and code agent, and while some features aren't as polished as CC, one of my explicit goals is to preserve the traditional CLI feel, like the python REPL (that's what it's based around). I'll give zmx a try tonight :)

I think people familiar with tmux/screen and tailscale or how to setup their own VPN might have.

Based on my experience many people don't know this is a thing you can do.

I'm still doing this. Is there a better setup? It's already very convenient and secure.

I always setup my terminals to open a tmux session by default (or attach to any existing one). For example, in my ~/.config/alacritty/alacritty.toml:

    [terminal.shell]
    args = ["-l", "-c", "tmux attach || tmux"]
    program = "/opt/homebrew/bin/zsh"

tmux supports tabs so you can have multiple Claude Code sessions running concurrently. You do need to learn a few tmux keyboard shortcuts to use it effectively (e.g. opening/closing/switching tab).

Sorry didn't answer "how important is mosh?"

Depends- how good is your signal? Mosh has a great property that it buffers everything locally so there's no lag even if your connection sucks.

On ssh, every keystroke is a roundtrip

"tmux ls" shows you all the open tmux sessions

Could even use cc to check in on and/or "send-keys"

What wasn't working about mosh? Just install mosh and use mosh to connect

I recommend Eternal Terminal instead of mosh for this.

It's this.

Don't have a Dropbox moment ;) [1]

Ease of setup is the biggest reason. I use this setup as well, but there are other UX niceties that would be a lot better with a dedicated mobile app: push notifications when Claude needs your input (I use a hook for this that connects to Pushover, but that's another service and extra setup), voice input, autocorrect that's right for this context, etc.
