Cmux Remote is a private remote-control client for the cmux terminal multiplexer running on your own computer. Connect over your Tailscale network — your traffic never touches a third-party relay.
WHAT IT IS
Cmux (https://cmux.com) is a modern terminal multiplexer with native splits, workspaces, and rich integrations for AI agents like Claude Code, Codex, omx, and Cursor. Cmux Remote mirrors the cmux surface you choose, lets you type into it, send keys,
manage workspaces, upload photos and documents, preview images, and receive notifications — all from this mobile app.
WHO IT IS FOR
- Developers who run long-lived agents such as Claude Code, Codex, and omx and want to check or control them away from their desk
- People who access their own development machine remotely and want a focused terminal experience
- Anyone already using Tailscale and looking for a private way to reach their terminal
HOW IT WORKS
1. Install the open-source cmux-relay binary on the computer that runs cmux.
2. Make sure that computer is connected to Tailscale.
3. Open this app, enter the computer’s Tailscale hostname, and tap Connect.
4. Your cmux workspaces appear. Select a surface and start working.
The relay communicates directly with cmux through its local Unix socket. This app communicates with the relay over a WireGuard-encrypted Tailscale tunnel. Nothing leaves your private network.
FEATURES

- Connected computer battery status when provided by the relay
- Pinch-to-zoom terminal font sizing

- Adds an Option + Down Arrow shortcut next to Option + Up Arrow.
- In Claude Code's fullscreen view, it can jump back to the latest output. Add "alt+down": "scroll:bottom" to the Scroll context in ~/.claude/keybindings.json on your Mac.
