Tessera - SSH Terminal

A fast, keyboard-first SSH, Mosh, and tmux terminal for iPhone and iPad.

Tessera is a fast, keyboard-first SSH, Mosh, and tmux terminal for iPhone and iPad. It connects directly to servers you own or control — no middleman, no account, no tracking.

MOVE BETWEEN YOUR DEVICES • Hand off a live session: start on iPad, pick it up on iPhone, then double-tap to take back control. The session keeps running either way. • Your focused session appears in the App Switcher and Dock on your other devices. • Nearby Setup copies your hosts, keys, and preferences to a new device directly over the local network — you choose exactly what to copy, both devices confirm a matching code, and each grant needs Face ID. • Or don't sync at all: choose whether sessions follow you or stay on each device.

STAY CONNECTED • First-class tmux integration: auto-attach on connect, so a dropped connection never loses your work. • Native tmux windows as tabs, with real panes. • Mosh keeps your session alive across Wi-Fi ↔ cellular roaming and sleep/wake — pick up exactly where you left off. • Session restore brings your saved hosts and layout back after relaunch.

BUILT FOR TOUCH AND KEYBOARD • First-class hardware-keyboard support: shortcuts, a key legend (⌘ hold), and careful handling of modifier keys for real terminal work. • A configurable swipe pad puts arrows, Esc, Ctrl and your own macros in the thumb zone. • Mouse and trackpad support, including scrolling that works. • Find-in-terminal, themes, and adjustable fonts and appearance. • Optional on-device dictation straight into the terminal.

FILES, PORTS, AND JUMP HOSTS • A remote file panel that tracks your shell's current directory, over SSH and mosh alike — with native iOS sharing to move files and images in and out. • Local port forwarding with a live tunnels overview. • Jump hosts for servers you can only reach through a bastion.

PRIVATE BY DEFAULT • Tessera has no servers, no analytics, and collects no data. Connections go directly from your iOS devices to your machines.

SECURITY YOU EXPECT • Keys are generated and stored in the iOS Keychain; Secure Enclave–backed keys never leave your device and can require Face ID to use. • Host-key verification with a persistent known-hosts store. • App lock with Face ID / passcode on launch, background return, and idle timeout.

OPEN SOURCE • Tessera is free software (GPL-3.0). The full source code is available at github.com/bambouville/tessera.

Tessera requires servers you provide — it is a client, not a hosting service. Mosh and tmux features require mosh/tmux installed on the server.
