Conduit

A local-first SSH, Mosh, and SFTP client for Android and iOS.

Conduit is for reaching real machines from your phone without signing into<br>anything. Hosts, keys, and trusted fingerprints stay on the device - no account,<br>no cloud sync, no subscription. Open a normal SSH shell, or a Mosh session that<br>rides out Wi-Fi drops and cellular handoffs instead of dying with them. Sessions<br>live in tabs, with on-screen modifier, arrow, and function keys for the things a<br>phone keyboard doesn't have.

There's an SFTP browser for moving files around, host-key trust you manage<br>yourself, an optional device-auth app lock, and a stack of built-in terminal<br>themes (Catppuccin, Tokyo Night, Gruvbox, Nord, and the usual suspects).

Mosh runs on dart_mosh, a clean-room<br>Dart implementation of the protocol, and the terminal is<br>conduit_vt, a fork of xterm.dart.

Features

SSH terminal sessions with saved machine profiles and tabbed workspaces.

Mosh sessions for roaming across Wi-Fi drops and network changes.

SFTP browser for navigating, downloading, uploading, renaming, and deleting files.

OpenSSH private key, password, and hardware security key authentication.

OpenSSH FIDO security-key auth for ed25519-sk and ecdsa-sk credentials,<br>tested with YubiKey and designed for CTAP-compatible keys.

Android hardware-key auth over USB or NFC; iOS hardware-key auth over NFC.

Trusted host key management with explicit fingerprint review.

On-screen terminal controls for modifiers, arrows, function keys, and common shell input.

Optional device-auth app lock for protecting saved machines and credentials.

Built-in terminal themes, font sizing, palette choices, and appearance controls.

Local-first storage: no account, no cloud sync, no subscription.
