AgenTTY is a fast, Ghostty-based SSH client for iPhone, purpose-built for power users of agentic AI coding TUIs such as Codex CLI and Claude Code. Unlike a typical iOS SSH client, AgenTTY is built around what actually matters when you run long-lived coding-agent sessions from your phone: staying connected, knowing the moment an agent needs you, and getting back into your session in seconds. FEATURES - Native iOS notifications when work finishes or an agent needs input - Paste screenshots and images directly into supported workflows from your phone - Persistent tmux sessions with quick reconnect - Resilient connections that survive network changes, backgrounding, and roaming between Wi-Fi and cellular - Long-press the spacebar for a fast shell quick switcher - AI-generated shell titles plus live folder and git-branch context - A custom keyboard built for terminal work, with familiar shortcuts and modifier slide-chords - Full support for iPad hardware keyboards - Whisper-based dictation for hands-free prompting on the go BUILT FOR LONG-RUNNING SESSIONS AgenTTY is especially good for Codex, Claude Code, tmux, and similar terminal-native AI workflows. Keep work alive in persistent shells, jump back in when an agent needs attention, and move quickly between sessions while you are away from your desk. NATIVE PERFORMANCE Built on an ultra-fast Ghostty core, AgenTTY delivers native-feeling performance and smooth terminal rendering on iPhone, even during heavy output and real CLI use. EASY HOST SETUP Run one `npx` helper command on the host, then scan its QR code or enter the short code in the app. AgenTTY reuses or creates a device SSH key automatically, keeps the private key local on your iPhone, and finishes the setup for you. REAL SSH ON IPHONE Even if you do not use AI coding agents at all, AgenTTY still stands on its own as a serious SSH client. Connect to your own machines with public-key authentication, host-key verification, persistent sessions, and a terminal that feels fast, responsive, and native on iPhone. SECURITY BY DEFAULT Generate Ed25519 keys on-device. Private keys stay in the iOS Keychain. Host keys are pinned with trust-on-first-use protection. AgenTTY includes a one-week free trial. After the trial, a one-time in-app purchase unlocks lifetime access. AgenTTY is an independent app and is not affiliated with OpenAI or Anthropic.
