Tessera docs

Tessera is an SSH, Mosh, and tmux terminal for iPad — fast, keyboard-first, and private by design. It connects directly to servers you own or control; there is no Tessera backend, no account, and no data collection.

Mosh and tmux features require mosh-server / tmux installed on the server.

What Tessera does

  • SSH and Mosh. Password and key authentication; Mosh keeps your session alive across Wi-Fi ↔ cellular roaming and sleep/wake.
  • tmux integration. Native control mode — auto-attach on connect so a dropped connection never loses your work; windows and panes are real UI.
  • Secure by design. Keys live in the iOS Keychain; Secure Enclave–backed P-256 keys never leave the device and can require Face ID to use. Host-key verification with a persistent known-hosts store, plus an app lock.
  • Local port forwarding to reach services behind your server.
  • Files beside your shell. A remote file panel that tracks your shell's directory, over SSH and mosh alike.
  • Agent center. Watch and answer Claude Code and Codex sessions across all your connections from one page (experimental).
  • Built for iPad. First-class hardware-keyboard support, a configurable swipe pad for the touch screen, Stage Manager / Split View, session restore, find-in-terminal, themes, and optional on-device dictation.
