iTmux vs ShellDiver

itmux is a fast, modern SSH terminal built around tmux. Connect to your servers, attach to real tmux sessions that keep running when you disconnect, and pick up exactly where you left off — from iPhone, iPad, or Mac. Unlike a plain SSH client, itmux speaks tmux natively. It uses tmux control mode to show your sessions, windows, and panes as first-class UI, so switching context is a tap instead of a memorized shortcut. KEY FEATURES • Native tmux integration — attach to and create sessions, switch windows, and split or navigate panes without typing prefix keys. • Persistent sessions — your work keeps running on the server; reconnect any time and everything is still there. • Flexible SSH auth — connect with a password, an on-device SSH key, or your SSH agent. A key pair is generated and stored securely in the Keychain; only the public key ever leaves your device. • Fast, full-color terminal — a responsive renderer with true-color support and a touch-friendly key bar for Esc, Ctrl, arrows, and other keys phones don't have. • Tabs and windows — keep multiple sessions in tabs; on Mac, tear a tab off into its own window. • Remote file browser & editor — browse the server's filesystem and edit files in a built-in editor, without leaving the app. • Host-side notes — keep quick notes stored on the server alongside your work. • Built-in VNC viewer — open a remote desktop in a standalone window over your SSH tunnel. • Voice dictation — hold to speak a command straight into the terminal (iOS). • 14 languages — the whole interface localizes and switches instantly. BUILT FOR iPHONE, iPAD, AND MAC itmux is a universal app. The iPad layout gives you a proper sidebar and large terminal; the Mac app adds tear-off tabs and native window management. Your connections and SSH key live on-device, in the Keychain. PRIVACY FIRST No account required. Your hosts, passwords, and keys stay on your device and are used only to make your own connections — never sent to us. The contents of your sessions, files, and notes are never transmitted to our servers. See the privacy policy for details. Great for developers, sysadmins, and anyone who lives in the terminal and wants their tmux sessions in their pocket. Questions or feedback? Email hswillg@gmail.com — we read every message.

With software, free is usually a question rather than an answer. Here it is arithmetic: no server of ours, no accounts, no analytics — nothing for a subscription to pay for. Sync, startup commands, port forwarding: all of it is in the app. WHERE YOUR KEYS LIVE In your device's keychain. ShellDiver has no account and no sign-in — there is simply nowhere on our side for anything of yours to sit. An Ed25519 key either travels with you through iCloud Keychain, end-to-end encrypted, or stays on this device behind Face ID. A Secure Enclave key is created inside the security chip. It cannot be read out — not even by ShellDiver — never leaves the device, and will ask for Face ID on every sign-in if you want it to. THE VAULT Instead of iCloud you can take syncing into your own hands: an encrypted file in a place you choose. A USB stick, a cloud folder, or your own WebDAV server, so Nextcloud, ownCloud, a Synology, an Apache with mod_dav. It works across different Apple IDs and carries the secrets with it: saved server passwords and private keys. Only your devices encrypt and decrypt. Whoever runs the storage location sees nothing but unreadable files. You add a second device with a QR code, without typing your passphrase there. THE TERMINAL It does not hang up because you looked somewhere else for a minute: the connection belongs to the session, not to the screen. The running build and the half-typed line are still there when you come back. Up to 20 sessions as tabs, terminals and files mixed. Real xterm emulation: colour, UTF-8, resizing that works — htop, vim and colourful logs look the way you expect. Plus search through the scrollback, your choice of monospaced font including Nerd Fonts, and five colour schemes. On iPhone there is a row above the keyboard with esc, ctrl, tab, arrows and a paste key, because a phone has no ⌘V. When the link drops, ShellDiver notices through keepalives and rebuilds it by itself. This is SSH, not Mosh: the new shell starts fresh. SIGNING IN WITHOUT GUESSING ShellDiver asks the server which methods it offers and works through whatever it holds credentials for. That covers publickey followed by keyboard-interactive — 2FA after the key — and equally a server that only offers keyboard-interactive while the host is saved as "password". One-time codes are never pre-filled and never stored. You confirm a host key once, by its fingerprint. Every connection after that checks it, and a key that has changed is refused rather than waved through. THROUGH A JUMP HOST When a server is only open on the inside, you give it a jump host — OpenSSH's ProxyJump. The jump host then forwards nothing but encrypted bytes and cannot read along; both sign-ins are signed on this device. So your key does not have to sit on the machine in between, and a Secure Enclave key works here too. FILES AND TUNNELS The SFTP browser downloads and uploads, whole folders included, renames, and deletes recursively. Local port forwarding brings a database or an admin interface onto this device. It listens on 127.0.0.1 only and cannot be reached from outside; each rule holds its own connection, so a tunnel does not fall with a terminal. WHAT YOU ALREADY HAVE Your ~/.ssh/config is imported, with each IdentityFile matched against the keys you have and any ProxyJump resolved; so is known_hosts, hashed entries as far as they can be matched. Keys come in as Ed25519, RSA or ECDSA — from the OpenSSH container, from PuTTY's .ppk (v2 and v3), and from the PEM family. A passphrase on the file is used once during import and not kept. Snippets are also the buttons above the keyboard — global or bound to one host, with a confirmation step if you want one. One per host runs by itself as soon as the shell is open. The backup is a JSON file you can read — secrets sit inside an encrypted block under a passphrase you choose. Without it nobody gets at them, us included.
