- Lightweight (80–150 MB RAM): Tauri 2 uses native OS webviews instead of bundling Chromium.
- Direct PTY Streaming: Rust streams raw pseudo-terminal bytes straight to
xterm.jsvia event emitters, avoiding IPC serialization overhead. - Zero-Binary JavaScript Rule: SFTP file transfers run directly between SSH socket and local disk in native Rust (128 KB buffered stream). JS runtime never touches file binaries.
- Virtualized File Explorer: Smooth rendering for directories with thousands of files powered by
@tanstack/react-virtual.
- Bidirectional PTY ↔ SFTP Sync: Terminal working directory and SFTP remote pane stay in sync automatically.
- Multi-Session Tabs: Connect, switch, and monitor multiple SSH hosts simultaneously.
- Resilient Auto-Reconnect: TCP keepalives (15s) and exponential backoff keep connections alive and restore buffers after dropouts.
- Flexible Split Layouts: Switch instantly between full terminal, full SFTP, or resizable dual split.
- Drag-and-Drop: Transfer files between local/remote panes, target folders, or directly from OS file explorer.
- In-App Code Editor: Built-in editor with syntax highlighting for remote and local configuration files.
- Transfer Conflict Resolution: Side-by-side comparison with Overwrite, Overwrite Newer, Size Differs, Auto-Rename, and Skip actions.
- Quick Search & Filter (
Ctrl+F): Real-time multi-token search across current directory contents. - Visual Permissions (chmod): Inspect and adjust octal permissions (
0755,0644) and flag bits visually.
- Encrypted Profile Vault: Host credentials encrypted with PBKDF2-HMAC-SHA256 (100k rounds) + AES-256-GCM (
vault.enc). - Biometrics & 2FA: Native OS passkeys (Windows Hello fingerprint/face/PIN) and RFC 6238 TOTP authenticators.
- Protection Gate: Requires biometric or 2FA setup before saving credentials to disk.
