Connectivity

Built for the way
real networks work.

SSH and Mosh cover every connectivity scenario — from a fast office LAN to a spotty mobile connection on the move. Both are fully free.

  • SSH2 — Full SSH2 protocol, unlimited connections and hosts
  • Mosh — UDP-based, survives IP changes and network drops
  • Multi-tab sessions — Unlimited concurrent connections, Ctrl+T to open
  • Auto-reconnect — Exponential backoff, countdown UI on disconnect
  • Keep-alive — Configurable interval to prevent session timeouts
  • Quick Connect — One-tap connect without saving a host
ssh — [email protected]

Security

Hardware-grade security.
No compromise.

Private keys never leave your device. They're stored in Android Keystore — hardware-backed, inaccessible even if the phone is rooted. No cloud, no exceptions.

  • Ed25519, RSA-4096, ECDSA — Generate, import, or export keys
  • Android Keystore — Hardware TEE lock; keys never exported in plaintext
  • SSH agent forwarding — Bastion host and git push support
  • Host key verification — TOFU with MITM warning on fingerprint change
  • Biometric app lock Pro — Fingerprint or face required to open app

SFTP

A full file manager.
An editor. Not a viewer.

Browse, upload, download, rename, delete — all free. The SFTP inline editor lets you edit config files, dotfiles, and scripts directly on the server without downloading first.

  • SFTP v3 — Browse, upload, download, multi-select, rename, delete
  • Read-only preview — View remote files without downloading
  • Inline editor Pro — Edit on server, 150+ file types, syntax highlighting
  • SHA-256 verification — Automatic checksum check on every transfer
  • Tablet split-pane — Host list and SFTP browser side-by-side on large screens
