Termcorp vs ShellDiver

Termcorp turns your iPhone and iPad into a window onto the coding agents running on your Mac. Your work lives in tmux, not in the app. Termcorp opens an SSH connection to your Mac (or any server), attaches a persistent tmux session, and mirrors the terminal. Close the app, lose the network, lock your phone - nothing stops. Reopen it, and you're right back where your agent left off. Built for developers and vibe coders who run AI agents in the terminal. WHY TERMCORP - Persistent sessions: your agent runs inside tmux on the Mac. The app is just a viewer; the work never stops. - Session recovery: open the same session on another device; it switches over, resizes, and the other view detaches. - Voice dictation: speak your prompt; it goes straight to the terminal. No copy-paste. - Attachments: photos, screenshots, PDFs and files land in your project, with the path inserted for you. - Built for touch: esc / ctrl / arrow key bar, swipe to scroll history, a keyboard you can tuck away. - Encrypted SSH: connection keys are stored in the iOS Keychain, never in the clear. The app has no servers and collects nothing. WORKS WITH ANY CLI Termcorp is a terminal. It drives whatever runs in it - Claude Code, OpenAI Codex, Gemini CLI, Aider, or a plain shell. FREE ON MAC Termcorp for Mac is a free companion app: a local terminal for your desktop. Termcorp for iPhone adds the mobility - pilot your agents from anywhere.

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.
