Termdeck vs tmux
tmux keeps a session alive so your agent survives a dropped SSH pipe. Termdeck does that for Claude Code, Codex, and Grok, then adds what a terminal multiplexer can’t: per-tool approvals, rendered diffs, push to your phone, and one board across every machine. Detach from the terminal, reattach from any device, no forked session. Miss the grid? The Terminals view shows every chat as a pane: tmux energy, zero setup.

| Two-writer safety | Manual | Lock prevents forked sessions |
| The pane grid | The whole point | Terminals view: every chat as a pane, every machine in one grid |
Keep tmux for your shells. Use Termdeck for your agents. It complements the terminal, it doesn’t replace it.
FAQ
You can, and the session survives a dropped connection. But tmux only holds a terminal, so you still get raw approval prompts, plain-text diffs, and no way to be paged when a run blocks. Termdeck keeps the session alive and adds the approval UI, diffs, and push on top. See the Claude Code web UI.
No. Keep tmux for shells and servers. Termdeck is the layer for coding agents: it streams Claude Code, Codex, and Grok to the browser, survives refreshes, and lets you take over from any device.
Yes. Close the terminal client and drive the same session from the web or your phone. A live-registry lock stops two writers from forking it, so takeover is safe.
Yes. Every machine and session shows up in one sidebar and a fleet board, with an attention badge on the runs waiting for you, so no cycling through panes.
Yes. The Terminals view renders every chat as a pane in one tmux-style grid: every machine, every engine, one screen. You keep the layout you love and gain approvals, diffs, and push.
