SSH terminal in your pocket. Full xterm-256color emulation, biometric-protected keys, tmux session attach, and on-device voice dictation. No accounts, no tracking β€” everything stays on your device. tunlr is built for developers, sysadmins, and DevOps engineers who need real terminal access on iPhone and iPad. β€” TERMINAL β€” 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. β€” TMUX SESSIONS β€” Pick up right where you left off. After connecting, tunlr lists the tmux sessions running on the server: attach to one, start a new one, or set a connection to always open the same session. When you return to the app, tunlr reconnects and re-attaches to the same session. Experimental support for zmx and agterm sessions. β€” AUTHENTICATION β€” Three ways to authenticate, all protected by Face ID or Touch ID: Secure Enclave keys β€” 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 β€” bring your own Ed25519, ECDSA, or RSA keys. Stored in the iOS Keychain with biometric protection. Passwords β€” stored in the Keychain, never in plain text. β€” HOST VERIFICATION β€” Trust-on-first-use (TOFU) host key verification. tunlr saves the server fingerprint on first connection and warns you if it ever changes.

All audio processing happens on your device β€” nothing is sent to any server. β€” KEYBOARD TOOLBAR β€” Customizable keyboard toolbar with sticky modifier keys. Shortcut packs for Shell, Tmux, Vim, and Claude Code workflows. Save your own favorites. β€” CONNECTIONS β€” Save server profiles with hostname, port, username, and authentication method.
