dotMux easy SSH with tmux

Remote tmux windows become native tabs; panes become native views — full-screen on iPhone, true side-by-side splits on iPad. Real SSH keys, Secure Enclave, Face ID.

Stop fighting tmux on a touchscreen.

dotMux speaks tmux control mode natively and rebuilds your remote workspace as real iOS UI — the way iTerm2 does on the Mac. Your remote tmux windows and panes become native tabs and views you drive entirely by touch.

NATIVE tmux, NOT raw text

• Remote tmux windows become native tabs.
• Every pane becomes a native view — focused full-screen on iPhone, true side-by-side splits on iPad.
• Split, resize, and close panes right from the app — pane menu, long-press, or keyboard shortcuts.
• Switch windows and panes by tapping or swiping, not by hunting for a prefix key.
• Select and copy text with native handles; tap links in the terminal to open them.
• If a host has no tmux, dotMux falls back gracefully to a plain terminal.

REAL SSH, DONE RIGHT

• Password and public-key authentication.
• Import your ed25519 keys by paste or from Files — passphrase-protected keys included.
• Or generate a key that lives in the Secure Enclave: non-exportable, signing happens in-chip, the private key never leaves the device.
• Connect directly from your device to your own servers. No middleman, no developer backend.

PICK UP WHERE YOU LEFT OFF

• The session picker lists every tmux session on the host and marks the ones already attached.
• Switch sessions in place, or create named ones on the fly.
• iOS suspended the app? Long-running jobs keep running on the server. When you come back, dotMux re-attaches to your tmux session and your tabs and panes rebuild themselves.

A KEYBOARD BUILT FOR TERMINALS

• A helper bar above the keyboard with the keys terminals actually need: Esc, Ctrl, Tab and more.
• Fully customizable: add, remove, and reorder keys — F-keys, Ctrl combos, arrows, even your own text snippets.
• A multi-line composer for drafting long commands and agent prompts, sent in one go.
• A drag-pad arrow joystick with press-and-hold repeat for cursor movement and shell history.
• Sticky modifiers, and a hide-to-floating-dock control when you want the screen back.
• Paste images from your clipboard — dotMux uploads them to the host and pastes the path (built for Claude Code).
• Native iOS 26 styling that respects your system tint.

MAKE IT YOURS

• Terminal fonts: JetBrains Mono, Fira Code, Hack, IBM Plex Mono and more.
• Color themes with live preview: Dracula, Nord, Solarized, Gruvbox, Tokyo Night, Catppuccin and others.
• Pinch to zoom with a live cols × rows readout; keep the screen awake while connected.

SECURITY THAT STAYS ON YOUR DEVICE

• Face ID app-lock, plus a second Face ID gate per credential, with a short configurable grace period.
• Credentials live in the Keychain and Secure Enclave, bound to this device — never synced to iCloud, never sent anywhere.
• A privacy cover hides the terminal in the app switcher.
• dotMux collects no data. No analytics, no tracking, no ads, no account, no sign-up.

MADE FOR iPad TOO

• One universal app for iPhone and iPad.
• Open hosts side by side in multiple windows; built for hardware keyboard and trackpad.

PRICING

• Free: save and connect to one host, fully featured.
• Unlimited Hosts: a one-time $1.99 purchase to save as many servers as you like. No subscription. Restore Purchases supported.

Note: RSA keys are not supported (modern OpenSSH disables the SHA-1 ssh-rsa signature). Use ed25519 or a Secure Enclave key.
