SuperDuper Terminal vs Bolt SSH

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
