Loopback: Tunnel Browser

Loopback is an iOS app that lets you securely access private web services via SSH local port forwarding, all inside a built‑in browser sandbox. Add servers, save bookmarks, and open your intranet apps in one tap. SSH tunnel: password or private key (Ed25519 / RSA) authentication. Built‑in WebView shares the same sandboxed network with the SSH tunnel. Bookmarks: save frequent services as cards with custom icon, color, path, and timeout (3–30s). Multi‑port forwarding: main port + additional ports for frontend/backend split apps. Keychain-secured credentials for passwords and private keys. Auto-disconnect on timeout/background; keep-alive heartbeats for stability. Backup & restore: export/import servers, bookmarks, and SSH keys (passwords obfuscated). Dark Mode support. Usage: add a server → create bookmarks → tap to connect → browse via localhost. Privacy: all data stored locally on-device; no analytics, no tracking, no cloud sync.
