Your AI coding agents are already running on your Mac. Port22 doesn't launch, wrap, or replace them — it attaches to what's there and puts every session on your phone, including a permission prompt you can answer in a tap. Start Claude Code, Codex, or OpenCode in whatever terminal you like. Nothing about your setup changes. Port22 just gives you the whole fleet from anywhere. HOW IT WORKS 1. Install the free Port22 agent on your Mac — it's a menu-bar app, no configuration. 2. Pair your phone by typing a six-character code. No account, no sign-up. 3. Your sessions appear. Start them however you already do. MISSION CONTROL FOR YOUR FLEET See every session at a glance: which agent is working, which one is blocked on you, which one is done. No log tailing, no raw error strings — just states a human can read. WHEN AN AGENT IS BLOCKED Your phone tells you the moment an agent needs permission. Open Port22 and every option the agent actually offered is there as a real button — never a guessed keystroke, never an inferred choice. Answer it and the agent carries on. THE REAL CONVERSATION Read the full transcript exactly as it happened — prose, tool calls, diffs. Send a new prompt. Answer a multiple-choice question with real buttons instead of guessed keystrokes. Nothing is truncated. WORKS OFF YOUR NETWORK On your network it connects directly over your LAN. Off it, it fails over automatically to an encrypted relay, and you keep working from anywhere. Taurine, our keep-awake mode, stops your Mac napping mid-run so a long job survives the walk to the coffee shop. END-TO-END ENCRYPTED Your Mac and your iPhone verify each other's identity when they connect, then talk over an AES-256-GCM encrypted channel that the relay in between cannot read. There is no account and no sign-up — pairing is a code you type once. FREE FOREVER One Mac and two sessions, with every feature unlocked. Not a trial and not a crippled tier: off-network access, permission approvals, Taurine, and the full conversation are all included. The two sessions you're using stay free. PORT22 UNLIMITED Unlimited Macs and unlimited sessions, so you can drive the whole fleet at once. An annual subscription that renews automatically until cancelled. Pricing is shown in the app. REQUIRES THE MAC AGENT Port22 needs the free Port22 companion app running on your Mac. Download it at tryport22.com.
