A full terminal, an SFTP browser, and your saved hosts on iPhone. No monthly fee, no account, and no server of ours in the middle.
Ctrl, Esc, Tab, the arrows and Ctrl+C sit above the keyboard, so you can interrupt a process, leave vim, and complete a path — the things you opened a terminal to do.
Every new host's key fingerprint is shown before you connect — and flagged in red if it ever changes.
Credentials are stored in the iOS Keychain, never on a server we run — because we don't run one. There is no account to create and nothing to sign in to.
Three saved hosts free. The terminal, SFTP, saved scripts and key generation aren't gated at all — the one purchase only lifts the host limit, and there's no subscription behind it.
Termius is about $120 a year. Blink is $19.99 a year, and no longer sells a perpetual licence at all. Malvek is $14.99, once — and there's no account to create, because there's no server behind it.
