SSH clients exist, but they all need key setup, port forwarding, or a public IP.</p> <p>I wanted something I could set up in 30 seconds.</p> <h2> How it works </h2> <ol> <li> <code>brew install termonmac</code> on your Mac</li> <li>Open the iOS app and scan the QR code</li> <li>You're in — full terminal, E2E encrypted</li> </ol> <p>That's it. No SSH keys, no port forwarding, no public IP needed.</p> <h2> What makes it different </h2> <ul> <li> <strong>Zero setup</strong> — QR code pairing, no configuration</li> <li> <strong>Remote Xcode build</strong> — build, archive, and upload to App Store from your phone</li> <li> <strong>E2E encrypted</strong> — Curve25519 + AES-256-GCM. The relay server only forwards ciphertext and cannot read your terminal content</li> <li> <strong>Auto-reconnect</strong> — network switches, subway tunnels, device sleep — your session stays alive with terminal history replay</li> </ul> <h2> Tech stack </h2> <ul> <li>iOS: SwiftUI + SwiftTerm</li> <li>Mac Agent: Swift CLI with forkpty()</li> <li>Relay: Cloudflare Workers + Durable Objects (WebSocket hibernation)</li> <li>Crypto: Apple CryptoKit (Curve25519, HKDF-SHA256, AES-GCM)</li> </ul> <h2> Pricing </h2> <p>Free with optional Pro ($0.99/mo) and Premium ($2.99/mo) upgrades.</p> <p><a href="https://apps.apple.com/us/app/termonmac/id6759218342" rel="noopener noreferrer">App Store</a> | <a href="https://termonmac.com" rel="noopener noreferrer">Website</a></p> <p>Would love to hear your feedback!</p> showdev swift terminal ios
