SigilTTY is a fast, native SSH client and terminal for iPhone, iPad, and Mac. Connect to your servers, run
commands, transfer files over SFTP, and open secure tunnels — with everything synced across your devices
through iCloud.
Built on a GPU-accelerated terminal (powered by Ghostty) and the battle-tested libssh2 engine, SigilTTY
feels instant and looks sharp on every screen.
CONNECT YOUR WAY
• SSH with password or private-key authentication
• Telnet for legacy devices and equipment

A REAL TERMINAL
• Native, GPU-accelerated rendering — smooth even under heavy output
• Multiple sessions with tabs
• Beautiful, iTerm2-compatible color themes
• Command snippets you can send with a single tap
FILES & TUNNELS
• Full SFTP file browser — upload, download, rename, delete
• Background transfers that never block your terminal
• Local (-L) and remote (-R) port forwarding
• SSH agent forwarding — the app answers the agent protocol itself, with no extra setup
SECURITY FIRST
• Credentials live in the Keychain, never in plain text
• Optional Face ID / Touch ID protection for private keys
• Trust-on-first-use host key verification warns you the moment a server's identity changes
• Key Handoff: hand a private key to another device over your local network, end-to-end encrypted and
confirmed with a verification code — the key never leaves your LAN
• No ads. No analytics. No tracking.
SYNCS EVERYWHERE
• Your servers, folders, snippets, and keys sync securely with iCloud
• Start on your Mac, pick up on your iPhone
