Ajar

Stop carrying your laptop around half-closed. Your Mac's terminal, from your phone.

In TestFlight — App Store release coming soon

The problem

You kick off a long task — Claude Code, Cursor, Codex, a build, a migration — and now you're tethered to the desk. So you carry the MacBook to the couch with the lid at 45 degrees, because if it sleeps, the session dies. Ajar is the app for that moment: leave the session ajar, walk away, and get it back on your phone.

Features

Plain SSH — connects straight to your Mac or server with your existing key. No account, no server to run, no cloud in the middle.
Real terminal — interactive PTY, scrollback, text selection, paste, hardware keyboards, and Esc/Ctrl/Tab/arrow controls.
tmux-native — discover, create, and reattach to sessions. Each host remembers its session, so coming back is one tap.
Find your Mac — nearby hosts show up on the local network; use a .local name and it follows you between Wi-Fi networks.
Keys stay yours — paste an Ed25519 or RSA key; keep it in memory, or save it on this iPhone behind Face ID, never in iCloud.
Host trust — first-use fingerprint approval, strict saved fingerprints, and an explicit review when a server's identity changes.
Completion alerts (Pro) — get a push when a shell command or agent turn finishes, even with Ajar in the background. Tap it to land back in the session.

Why plain SSH

Most "control your coding agent from your phone" apps want you to run their server on your machine and route your sessions through their UI. Ajar is a terminal. It works with whatever is already running — tmux, your shell, your agents — and the only thing it ever installs on the Mac is a small, reviewed helper for alerts, and only if you turn Pro alerts on. Your code and your keys never pass through a third party.

Pricing

The terminal is free: SSH, tmux, saved hosts, protected keys. Ajar Pro adds completion alerts for $2.99/month or $19.99/year, with a 7-day free trial.
