run-kit
run-kit is an agent-agnostic remote console for your tmux — every session and pane as a live terminal, in a sidebar, from your desk or your phone (mobile-friendly over Tailscale). It never wraps what’s in the pane: a pane is equally an AI coding agent, a dev server, a REPL, or an ssh session. run-kit riff spawns each parallel workspace in its own git worktree; run-kit serve opens the dashboard that watches them all. Because it exposes your tmux rather than any one agent’s protocol, it outlives whatever coding agent you’re running this month.

How it fits
Section titled “How it fits”run-kit is the window onto everything else: it watches the agent sessions running in your wt worktrees, so a whole fan-out of parallel changes lives on one screen. Pair it with tu to keep the running cost of those sessions in view.
