Terminalko vs ShellDiver

Terminalko is a fast, focused SSH terminal for iPhone and iPad. Connect to your VPS, Raspberry Pi or any Linux box, run a real shell, get work done without a laptop. Free to use, no account: add a server and you are at a prompt in a minute. [ A real terminal ] A true xterm-256color PTY with ANSI colors, scrollback and a keyboard aware layout. htop, vim and tmux behave exactly like they should. [ SSH, Mosh and Telnet ] SSH with password or key auth, jump hosts through a bastion in one hop. Mosh survives Wi-Fi to cellular switches, IP changes and long sleeps. Your prompt is still there hours later. Telnet for legacy gear: switches, routers, the odd BBS. [ Edit files over SFTP ] Open the config, fix the wrong line, save it back in place. Sizes, permissions and dates on every row. Upload, download, rename, delete, new folder. [ SSH keys, Secure Enclave included ] Generate an Ed25519 key on device and copy its authorized_keys line, ready to deploy. Paste an existing OpenSSH key. Or make one in the Secure Enclave, where the private half cannot leave the chip. A different key per server. Secrets live in the iOS Keychain. [ Dropped connections reconnect ] Connection Keeper retries a dropped session with a visible overlay and a cancel button. Lock the phone, tmux keeps working server side, the session re-attaches when you return. [ Themes and fonts ] Fifteen built in themes, plus an editor for your own: all 16 ANSI slots, text, background, cursor and selection, live preview. Twenty monospace faces bundled, nothing to download. [ Maximum Privacy and Security ] No tracking, no ads, no spying. Face ID, Touch ID, Optic ID or your passcode, with a grace period you choose, and masks it in the app switcher. No analytics, no ads, no accounts, no telemetry. The app talks to your servers and to nothing else. [ Want more? Unlock Terminalko Pro - one time purchase ] Most of Terminalko is free: every protocol, keys, jump hosts, themes, and the SFTP browser with full read access. Pro is a single payment (no subscription because we hate them). Pro adds the SFTP editor, the theme editor, the extra fonts and unlimited saved servers. [ Our mission ] Make the best terminal and SFTP app there is. Every version came from someone saying what was missing. If something is missing for you, say so. [ Requirements ] iOS or iPadOS 17 or later. Built for developers, sysadmins and homelab tinkerers. Check a server from the couch, SSH into a Pi from bed, restart a service from the train.

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.
