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.

Hermex is a native iPhone and iPad client for your self-hosted Hermes agent. Connect to a reachable Hermes Web UI server, or enable the optional Bot Mode beta to connect directly to a Hermes agent host. Open existing sessions, start conversations, and follow streamed responses, tools, and reasoning as they arrive. Queue, steer, or stop an active run. Review file edits as diffs, browse workspace files, send photos and files, and dictate messages. Manage Kanban boards and cards, browse Tasks, Skills, Memory, and Usage, and choose models, profiles, and reasoning settings. Bot Mode adds a Bots inbox, Desktop sections, reactions, quick replies, approvals, questions, and group rooms. Live Activities keep working runs visible on the Lock Screen and Dynamic Island. Optional notifications let you know when work finishes or needs your attention. The share extension stages content from other apps for you to review and send. Agent execution happens on your configured server, not on the iPhone. Your server owns your conversations, tools, and workspace. Recent sessions and messages may be cached locally for read-only offline viewing; clear that cache from Settings. There is no Hermex-hosted agent backend, tracking, or analytics service. Optional push notifications use an open-source, self-hostable relay. Message previews are encrypted on your Hermes host and decrypted on your iPhone; the relay handles device tokens, notification metadata, and ciphertext, never message text, server URLs, or Hermes server credentials. Push is off until enabled. Hermex has no in-app account creation or in-app purchases. You need your own reachable Hermes server. Not affiliated with Nous Research.

Verdict

The call

The clearest difference is in-app purchases: Hermex at none against AgenTTY's 1. Hermex also leads on rating (4.7 vs 4.3) and ratings volume (135 vs 4). AgenTTY's advantage is update cadence (daily vs weekly) and review sentiment (100% vs 85%). On price, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Hermex holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: Hermex has 135 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 100% of AgenTTY's written reviews are positive against 85% of Hermex's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

AgenTTY ships an update daily, Hermex weekly. The most recent releases landed on September 25, 2026 and October 9, 2026 respectively.
