## What is Cmux Remote?

Cmux Remote is a private remote-control client for the cmux terminal multiplexer running on your own computer. Connect through your Tailscale network so your terminal traffic stays between your own devices and does not pass through any developer-controlled server.

WHAT IT IS

Cmux is a modern terminal multiplexer with workspaces, split surfaces, and integrations for AI coding tools such as Claude Code, Codex, omx, and Cursor. Cmux Remote mirrors the cmux surface you choose, lets you type into it, send keys, switch workspaces, and receive local notifications from a mobile device.

WHO IT IS FOR

This app is for developers who keep long-running coding agents, builds, servers, terminals, or command-line tools active on a personal development machine and want a simple way to check progress or send quick input while away from the desk. It is also useful for people who already use SSH or Tailscale to reach their own computer and want a more focused remote terminal control experience.

HOW IT WORKS

First, install the open-source cmux-relay helper on the computer that runs cmux. Then connect that computer and this device to the same Tailscale tailnet. Open Cmux Remote, enter the computer's Tailscale hostname and relay port, and connect. Your cmux workspaces appear in the app. Choose a surface and start interacting with it.

The relay talks directly to cmux through its local Unix socket. Cmux Remote talks to the relay through a WireGuard-encrypted Tailscale tunnel. There is no hosted backend for terminal data, no analytics pipeline, and no external relay service controlled by the app developer.

FEATURES

Live cmux surface mirroring with ANSI color support.
Korean and CJK character width handling.
Keyboard accessory controls for Esc, Enter, Tab, arrow keys, and Ctrl combinations.
Mouse passthrough support for compatible terminal UIs such as Textual, Bubble Tea, and fzf.
Local notifications for cmux events without an external notification server in version 1.0.
Workspace and surface switching with compact controls.
Pinch-to-zoom terminal font sizing.
Automatic scroll-to-bottom behavior when changing surfaces.
Demo Mode with populated sample data so you can try the interface before setting up a relay.

PRIVACY

Cmux Remote does not include analytics, advertising, or third-party SDK tracking. The bearer token issued by your relay is stored only in secure credential storage on your device. Terminal content and control messages are exchanged only between your device and your own relay over your Tailscale network.

Source code and privacy details are available at:
https://github.com/NewTurn2017/cmux-remote

REQUIREMENTS

A personal computer running cmux 0.64 or later.
The open-source cmux-relay helper installed on that computer.
Both devices connected to the same Tailscale tailnet.
A compatible mobile operating system version for this app.

Cmux Remote is open source under the MIT license. Issues and pull requests are welcome.

### 5/5 — flawless cmux remote access

*2026-07-29*

works great! thank you for making this.

### 4/5 — Clever app, I like it. Please add:

*2026-06-18*

Would be great to be able to highlight and copy terminal text- right now you have to screenshot. Also- something is weird with double dashes, making it hard to prompt from the app. It’s a clever little app, these features would make a big difference!

### 5/5 — Does not work with current version of cmux relay.

## Version history (last 5 releases)

### 1.0.9 — 2026-08-03

cmux Remote 1.0.9 introduces a native tablet workspace designed for wide terminal sessions.

   - Uses the full tablet window instead of phone compatibility framing.
   - Reorganizes command input, utility actions, and shortcuts into a compact two-row landscape deck.
   - Keeps the terminal full-width and gives terminal text a more readable default size on larger screens.
   - Provides large touch targets, system text scaling, keyboard focus, Return-key submission, and visible status feedback.
   - Keeps shortcut keys usable even while a sent or error message is displayed.
   - Preserves the existing phone layout and interaction behavior.
   - Supports all four tablet orientations, including during multitasking.

### 1.0.8 — 2026-07-23

Cmux Remote 1.0.8 focuses on mobile terminal input polish, keyboard shortcuts, quieter notifications, and refreshed App Store copy.

- Adds LIVE input mode for immediate per-character terminal input, so English typing and quick key edits can be sent without pressing Enter or Submit.
- Protects Korean/Hangul IME input by keeping composed Korean text out of LIVE immediate-send mode, preventing jamo from being split while typing.
- Adds a dedicated Ctrl-C shortcut to the terminal keyboard bar for interrupting commands while coding.
- Removes the bottom gap under the terminal input panel so the composer sits flush with the bottom edge when the software keyboard is hidden.
- Adds five terminal rows of extra bottom scroll room, making it possible to pull terminal content above the input panel when the bottom rows would otherwise be covered.
- Adds native Inbox push delivery for cmux events and Claude/Codex-style "needs input" prompts, with APNs-backed routing and regression coverage.
- Adds a Settings control to reduce notification noise — only events that need your input raise an iOS banner, while everything still lands in the Inbox with unread badges.
- Fixes overlapping Korean/CJK text in the terminal mirror, so wide Hangul glyphs no longer bleed into neighboring columns on wide panes.
- Stops iOS smart punctuation from turning "--" into an em dash in the command composer, so CLI flags reach the terminal verbatim.
- Refreshes all five App Store screenshots to match the latest workspace, terminal, keyboard, Inbox, and settings screens.
