tunlr vs Conduit

SSH terminal in your pocket. Full xterm-256color emulation, biometric-protected keys, tmux session attach, 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. — TMUX SESSIONS — 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. — 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 — 24 color themes, dark and light: Default Dark, Solarized Dark, Solarized Light, Dracula, Nord, Monokai, One Dark, One Light, GitHub Dark, GitHub Light, Gruvbox Dark, Gruvbox Light, Catppuccin Mocha, Catppuccin Latte, Tokyo Night, Tokyo Night Day, Rosé Pine, Rosé Pine Dawn, Everforest Dark, Ayu Mirage, Night Owl, Tomorrow Night, 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.

Conduit is a local-first SSH, Mosh, and SFTP client for iPhone. It is built for people who need to reach real machines from a phone without creating an account, syncing credentials through a service, or paying a subscription just to open a shell. Use Conduit to connect to your own servers, workstations, homelab machines, VPS instances, and development environments from a mobile terminal. Features: • SSH terminal sessions • Password, private key, and hardware security key (FIDO2) authentication • Hardware security key auth over NFC, tested with YubiKey • SSH agent forwarding to reach further hosts from a machine you connect to • Per-host tmux integration with auto attach/create, start directories, prefix key selection, action shortcuts, and scrollback mode. • Experimental Mosh roaming for unreliable mobile networks • SFTP file browsing and export • Saved machine profiles with tags and search • Local credential and trusted host key storage • Trusted host key prompts and key management • Optional app lock with device authentication • Tabbed terminal workspace • Mobile-friendly modifier, navigation, and function keys • Fullscreen terminal mode • Built-in terminal themes With SSH agent forwarding, a host you connect to can use your key to authenticate onward to other machines, without copying private keys to the server. Forwarded hardware keys stay protected: every onward signature still requires your PIN and a physical tap. Conduit does not require a Conduit account and does not use a Conduit sync service. Saved connection profiles, credentials, and trusted host keys are stored on your device using platform secure storage. Conduit is free and open-source software licensed under the Apache License 2.0. Source code is available at github.com/gwitko/Conduit. Mosh requires mosh-server on the remote host and reachable UDP ports. Predictive echo is marked as experimental.
