Features

• AI assistant (multi-backend)
  • Works with any OpenAI-compatible endpoint — OpenAI, Ollama, vLLM, TGI, self-hosted gateways.
  • Knows the connected system (OS / shell / user / cwd) and can attach the focused pane's recent output, so suggestions fit the machine and what you're doing.
  • Extracts commands from responses into cards with a one-click Send to terminal button.
  • Per-tab conversations, saved chat history, and session restore.
• SSH manager
  • Host profiles (name / host / port / user / auth), groups, tags, search and sort, with keyboard navigation (↑/↓ to select, Enter to open).
  • SSH key manager: generate or import keys.
  • TOFU host-key verification with known_hosts — first-contact confirmation and mismatch warnings to guard against man-in-the-middle attacks.
  • Password prompt with optional save to the OS keychain (no plaintext on disk).
• SFTP file browser
  • Dual local ↔ remote panes, upload/download with a progress bar and transfer queue.
  • Remote file search and Unix permission editing.
• Terminal core
  • PTY-backed local shells, rendered with xterm.js (WebGL-accelerated).
  • Tabs, split panes (horizontal / vertical), and detach a tab into a new window (the live session and screen are handed over).
  • Session restore — on restart the previous tabs reopen: layout, local shells in their previous working directory, SSH tabs reconnecting, tmux panes re-attaching.
  • tmux integration — per-host auto-attach on SSH connect, a ⌘K tmux session picker (local or remote, with attach/switch/create), and tab titles that follow the session.
  • Dead-session detection — if the connection drops (e.g. after sleep), the tab says so and Enter reconnects in place (back into tmux when auto-attach is set).
  • Command history search (Ctrl/⌘ + R), inline autocomplete from history (accept with →/End; Tab stays shell completion), and a configurable default start directory for new terminals.
• UI
  • Collapsible left host panel and right AI panel, with draggable widths.
  • 11 UI languages (auto-detected from your OS locale, switchable in Settings).
  • Dark / light themes, configurable font and scrollback.
  • Import/export of hosts, groups, tags, and LLM backends (secrets and API keys stay in the keychain — re-enter keys after importing).

Tech stack

• Backend: Rust + Tauri 2
• Frontend: React 19 + TypeScript + Vite
• Terminal: xterm.js + portable-pty
• SSH/SFTP: russh + russh-sftp
• Secrets: OS keychain via keyring

Getting started

Prerequisites: Rust (stable), Node.js 20+, and platform build dependencies. On Linux you also need libwebkit2gtk-4.1-dev, libgtk-3-dev, and related packages. See the Tauri prerequisites guide.

npm install
npm run tauri dev      # development build with hot reload
npm run tauri build    # production bundle

The first launch shows a short onboarding flow. After that you land on a local shell tab.

Documentation

User guides live in docs/guide/:

• Getting started — install, first run, the workspace layout
• SSH — hosts, keys, host-key verification, saved credentials
• SFTP — the file browser, transfers, permissions
• AI assistant — backends, context, running suggested commands
• Keyboard shortcuts
• Release code signing — for maintainers building signed releases

Design notes are in docs/design/; the dated development log is in docs/work-log/.

Security

• API keys, SSH private keys, and passwords are never stored in plaintext — they live in the OS keychain (Keychain on macOS, Credential Manager on Windows, Secret Service on Linux).
• Host/group/tag export does not include secrets.
• SSH connections verify host keys against known_hosts (trust-on-first-use).
