I switched to herdr this year after a decade of using tmux, and I haven't looked back since. Herdr is wonderful, not only because of th coding agent integrations, but also because it uses libghostty under the hood. So no terminal-emulator-inside-another-terminal-emulator shenanigans.

If you prefer GUIs, I can recommend herdr-gpui which connects to a herdr daemon. It has a bunch of goodies like remote phone pairing, and a built-in browser integration to send screenshots and notes to coding agents.
