SuperDuper Terminal vs pmosh

SuperDuper Terminal is a small, fast SSH client for iPhone, built for the way people actually work with a remote box from a phone: check on a long-running job, restart a service, answer a prompt from an agent that is still running. WHAT IT DOES • Full SSH terminal with a real PTY — colours, cursor keys, everything a shell expects • tmux sessions by default, so closing the app or losing signal does not kill your work; reconnect and you are exactly where you left off • Multiple servers and multiple live sessions, switchable from a tab strip • A keyboard row built for the command line: Esc, Ctrl, Tab, arrows, pipe and slash — the keys iOS hides from you • Ed25519, ECDSA and RSA keys generated on device and stored in the Keychain, protected by Face ID • Port forwarding for the times you need a remote port on your phone KEYS STAY ON THE DEVICE Private keys are generated on the iPhone and kept in the Keychain, guarded by Face ID or your passcode. They are never uploaded, never synced to us, and there is no account to create. The app talks to your servers and to nobody else — there is no analytics SDK and no backend of ours in the path. BUILT FOR WORKING WITH CODING AGENTS If you run Claude Code or a similar agent on a VPS, the terminal keeps the session alive under tmux and gives you a one-tap way to answer it from your phone. The accessory row includes shortcuts for the keys those tools ask for most. Open source: github.com/fortunto2/swift-terminal

pmosh is an SSH terminal for iPhone and iPad that attaches to a tmux session on your own server using tmux's control mode, so the terminal you see on your phone is the same session running on your machine. It's built for developers who run tmux, shells, and command-line tools — including agentic coding tools like Claude Code — on servers or machines they already own and administer. pmosh doesn't provide any of that for you; it's a client that connects to infrastructure you already have. pmosh only connects to servers you configure. On first launch it generates an ed25519 SSH keypair on your device, stored in the iOS Keychain, and shows you the public key so you can add it to authorized_keys on your own server. You type in your host and username; nothing is pre-filled or bundled. There is no server component, no bundled credentials, and no third-party service in between. Features: - Attaches to a remote tmux session over SSH using tmux's control mode (tmux -CC), so output and session state stay in sync with the server - On-device ed25519 key generation — a unique keypair per install, kept in the iOS Keychain - On-screen keyboard toolbar with the keys terminal work needs but the iOS keyboard doesn't have: Esc, Ctrl, arrows, and tmux copy-mode scrolling - Works with an external hardware keyboard if you use one - Multiple tabs, each its own tmux session - No accounts, no sign-in, no subscriptions Privacy: pmosh does not collect analytics or usage data, and does not talk to any server other than the one you enter in setup. There is no account system and no data is sent to the developer or any third party. The only network connection the app makes is the SSH connection to your own server. Requirements: pmosh needs an SSH server you control, reachable from your device, with tmux installed on it. It is not a hosting service and does not include a server — you connect it to a server you already run.
