CodeGrid vs. tmux

tmux is a battle-tested terminal multiplexer: persistent sessions, splits, and full keyboard control, scriptable to the hilt. CodeGrid is a native macOS app built specifically for running many AI coding agents at once — a visual 2D canvas instead of stacked splits, with awareness of what each agent is doing. Both run your real CLIs; they solve different halves of the problem.

If you live in the terminal and love scripting, tmux is hard to beat. If you're orchestrating a dozen AI agents and want to see and steer all of them at a glance, that's exactly what CodeGrid is for — and you can still run tmux inside a CodeGrid pane.
