Real multi-window, on iPad and Vision Pro.

Every attached session is its own window: floating spatial windows you place around the room on Vision Pro, real scenes in Stage Manager and Split View on iPad. Merge windows into tabs and split them back out; the SSH connection, buffer, and scrollback move with the tab. Detach, and the wall still shows it running. On Vision Pro, an optional Glass appearance smokes the chassis so the room shows through.

Run herdr? First‑class, per host.

tmux is the default, not a requirement. Each host picks its backend — tmux, herdr 0.7.5+, or both at once — and herdr sessions get the whole app: a live tile with workspaces on its spine, attach in its own window, merge and split, file drops, agent chips and history.

• Both backends, one deckMachine runs both? Each refresh quietly notices; the host’s rail offers herdr’s sessions with the extra checking cost stated, and its tiles join in a lighter chassis.
• New sessions where you sayTick tmux, herdr, or both, and choose which one new sessions run on — a choice New Session, Shortcuts, the Host widget, and Add Host → BIND all carry.
• Its own controlsAn HRDR shortcut panel for splits, tabs, and workspaces, a New Tab in Workspace action, and herdr’s own pane menu one long-press away.

Watch over Claude Code, from anywhere.

Multiplex spots Claude Code, Codex, and Pi in every pane, right on the wall.

• One-tap command chipsStop, clear, compact, model and thinking switches follow the foreground agent, even in a plain SSH shell.
• Custom commands that travelPer host and per agent, multiline if you like, synced to your other devices with the host.
• Alerts when it needs youPROA finished turn, a question, a permission prompt: get notified instead of babysitting — and an optional per-host keep-alive keeps watch for a while after you switch away.
• Prompt history with jumpPROEvery prompt from Claude Code's own session file, one tap to jump the transcript back to it.

Add a host from its own terminal.

Run mpx bind on the machine. It offers itself with a QR code right in the terminal and an announcement on your local network; scan it or type the PIN, the machine confirms on its own screen, and it lands on the wall.

• No secrets typed, none pastedMultiplex generates a fresh ed25519 key per host and sends only the public half; the private key never leaves your device.
• Reversible by nameThe enrolled key is labeled in authorized_keys, so mpx unbind removes exactly what bind added — nothing else.
• One small CLIPrebuilt for macOS and Linux: Homebrew, a one-line installer, or a checksummed download — the install guide covers all three.
