gterm: Ghostty SSH

A real terminal in your pocket. Ghostty's GPU engine, native SSH, on-device keys, and an AI assistant that writes the commands for you.

gterm is a real terminal for iOS. It renders with Ghostty's GPU engine for true xterm/VT emulation, connects straight to your servers over SSH, keeps your keys on device, and ships an AI command assistant that writes the commands for you.

It's the same renderer and VT parser as the Ghostty desktop app. iOS can't fork/exec a local shell, so gterm drives the terminal straight from the SSH stream through a custom passthru IO backend added to libghostty — giving you a real terminal in a sandboxed iOS surface.

GPU-RENDERED TERMINAL Real xterm/VT emulation via Ghostty's libghostty, drawn on Metal. Colors, ligatures, and reflow that feel native — not a web shim.

SSH-NATIVE Connects with swift-nio-ssh — password and public-key auth, a PTY shell, live window resizing, and trust-on-first-use host-key verification.

KEYS STAY ON DEVICE Import Ed25519 / ECDSA private keys into the iOS Keychain — device-only, never synced. Pick one or more keys to try per host.

SHELL-GRADE KEYBOARD A custom accessory keyboard with the keys iOS forgets — Esc, Ctrl, Alt, Tab, arrows, and sticky modifiers for real TUI navigation.

AI COMMAND ASSISTANT Describe what you want in plain English. The AI reads your recent commands and visible screen, proposes a command, and shows it to you for review before it runs.

AI AUTO-COMPLETION As you type, suggestions surface above the keyboard — from your history and from your provider. Bring your own key; it's stored masked in the Keychain.
