tunlr

SSH terminal in your pocket. Full xterm-256color emulation, biometric-protected keys, and on-device voice dictation. No accounts, no tracking — everything stays on your device.

tunlr is built for developers, sysadmins, and DevOps engineers who need real terminal access on iPhone and iPad.


— TERMINAL —

Full PTY terminal emulation powered by SwiftTerm. xterm-256color support. Configurable scrollback buffer up to 50,000 lines. Optional Metal GPU-accelerated rendering. Works in portrait and landscape on both iPhone and iPad.


— AUTHENTICATION —

Three ways to authenticate, all protected by Face ID or Touch ID:

Secure Enclave keys — generate a P-256 ECDSA key that never leaves your device's Secure Enclave. The private key is inaccessible even to the app itself.

Imported keys — bring your own Ed25519, ECDSA, or RSA keys. Stored in the iOS Keychain with biometric protection.

Passwords — stored in the Keychain, never in plain text.


— HOST VERIFICATION —

Trust-on-first-use (TOFU) host key verification. tunlr saves the server fingerprint on first connection and warns you if it ever changes. Import fingerprints by scanning a QR code to skip the initial trust step.


— VOICE INPUT —

Dictate terminal commands with on-device speech recognition powered by WhisperKit. All audio processing happens on your device — nothing is sent to any server.


— KEYBOARD TOOLBAR —

Customizable keyboard toolbar with sticky modifier keys. Shortcut packs for Shell, Tmux, Vim, and Claude Code workflows. Save your own favorites.


— CONNECTIONS —

Save server profiles with hostname, port, username, and authentication method. Connect with a single tap. Auto-reconnect restores your session when you return to the app, with configurable keepalive intervals.


— APPEARANCE —

14 color themes: Default Dark, Solarized Dark, Solarized Light, Dracula, Nord, Monokai, One Dark, GitHub Light, Gruvbox Light, Catppuccin Mocha, Tokyo Night, Rosé Pine, Synthwave, and Kanagawa. Four monospace fonts and adjustable font size.


— PRIVACY —

No accounts. No analytics. No tracking. No data collection. Everything runs on your device. SSH connections go directly to your servers — tunlr never contacts any third-party service.
