Submarine (SSH, SFTP, Terminal)

At a glance:

• One window, many tools per server — terminal, SFTP, tunnels, folder mirror, Docker, live server info, and a per-server command library, all as tabs around the same session
• Watch many servers at once — session split view to tile any two sessions side-by-side, plus a global Wall pinboard for arbitrary terminals across hosts in a grid you control
• Broadcast input — type once, send to N selected sessions simultaneously (Tmux synchronize-panes for cross-server) Native and cross-platform — Windows, macOS, Linux (.deb / .rpm / Arch / AppImage), and Android — same encrypted vault everywhere
• Zero-knowledge cloud sync — profiles are Argon2id + AES-256-GCM sealed on your device before upload; the server (and everyone else) only sees ciphertext. Browser dashboard at api.sinaxhpm.com/account to manage your account and stored profiles
• Docker manager — containers, logs (live tail), stats, prune, and docker exec shells as first-class session tabs
• Import from anywhere — PuTTY .reg, MobaXterm .mxtsessions, OpenSSH config, and Submarine JSON exports all bulk-imported from the Servers page
• Secure by default — TOFU host keys with per-connection nonce binding, strict CSP, minimal Tauri permission ACL, zeroized master key
