Mitchell Hashimoto (@mitchellh) demoed the Superlogical Rex multiplexer CLI: everything in the GUI is scriptable, plus more—create sessions, run commands, split panes, move focus, simulate key/mouse input, and wait on scripts. A streaming event system lets any client hook in, and a terminal API returns running-process JSON for editors and agentic coding tools.

Key Takeaways

  • ✓Rex CLI matches and exceeds the GUI: sessions, commands, splits, focus, and input simulation are scriptable.
  • ✓Streaming events can be subscribed by any client or script.
  • ✓Terminal API returns running-process JSON for editors and coding agents.
