Cortex Relay vs Hermit SSH

Run Claude Code (or Codex and any other AI agent) from your iPhone. Cortex Relay gives you two ways to work with Claude Code on a remote machine — a friendly chat UI and a full-blown SSH terminal. Pick the right tool for the moment. THE CHAT Speak or type a prompt. Claude Code runs on your server, and the response streams back as a clean conversation with tool activity, cost breakdowns, and one-tap shortcuts for common tasks like committing, reviewing branches, or checking status. Upload photos from your camera roll and Claude can see them too. THE TERMINAL A real SSH terminal session. Cortex Relay renders the full CLI experience — interactive permission prompts, slash commands, MCP integrations, vim, git, whatever you need. Seven color themes from Nord to Dracula, pinch to resize, and a shortcut bar for /compact, /clear, /model, /status, and /cost. VOICE INPUT On-device speech recognition powered by OpenAI's Whisper. Pick a model size (tiny, base, small) and language (English or multilingual). Runs entirely on your phone — no server round-trip, works offline. Apple's built-in speech engine is available by default too. SESSIONS THAT SURVIVE Every terminal session runs inside tmux. Background the app, lose WiFi, switch to a call — your session keeps running on the server. Come back and everything is exactly where you left off. No reconnect dance. NOTIFICATIONS Get a push when Claude finishes a long task or needs your approval. The chat sends these automatically. For terminal sessions, drop a one-line webhook into your project's CLAUDE.md and Claude does the rest. SECURE BY DEFAULT Generate ed25519 SSH keys directly in the app or import your existing ones. Keys live in the iOS Keychain, optionally locked behind Face ID or Touch ID. Password auth is supported too, with the same biometric protection. Your credentials never leave the device. ORGANIZED Create named servers with saved directories. Spin up Chat or Terminal connections to any project on any machine. Each connection remembers its own dictation preferences. One server, many projects, zero re-entering credentials. YOUR TERMINAL, YOUR WAY Navy, Homebrew, Nord, Dracula, Solarized Dark, One Dark, Pure Black — pick a theme, see it applied instantly. Pinch to zoom the font size. It sticks between sessions. WHAT STAYS ON YOUR PHONE - SSH keys and passwords in iOS Keychain with biometric lock - Whisper speech recognition runs on-device only - No credentials sent to our servers - Push relay handles notification delivery — nothing else

Hermit is a focused SSH client built for developers who work with AI coding assistants on remote machines. Connect to your dev server, attach to tmux sessions, and interact using configurable soft keys and voice input. Unlike general-purpose terminal apps, Hermit is designed around a specific workflow: you have an AI CLI tool running in a tmux session on a remote machine, and you want to monitor and interact with it from your phone. Five soft keys — 1, 2, Enter, Escape, and a microphone — give you everything you need to approve tool calls, reject changes, send commands, and dictate instructions. KEY FEATURES * SSH connections with ed25519 private key authentication * Automatic tmux session attach on connect * Configurable soft key ribbon bar optimized for AI coding workflows * Voice input with iOS dictation — speak your instructions, proofread, and send * xterm.js terminal rendering with proper color and escape code support * Automatic iCloud Drive sync — your hosts and sessions available on all devices * Dark mode interface designed for terminal use * Private keys stored securely in the iOS Keychain BUILT FOR AI CODING WORKFLOWS The default soft keys map directly to common AI CLI approval patterns: 1 — Accept (approve tool calls and edits) 2 — Reject Enter — Confirm multi-line input Escape — Cancel or interrupt Mic — Open voice input for longer instructions OPEN SOURCE Hermit is open source so you can review exactly what runs on your device and how your SSH credentials are handled. No analytics, no tracking, no data collection.
