Conduit: SSH, Mosh & SFTP
Grzegorz Witkowski
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.
