Tempest 3 vs Shellter

Tempest is the SSH and Remote Desktop client built for people who actually manage servers. Connect via SSH, SFTP, or Mosh. Forward ports. Transfer files. Manage Kubernetes clusters. Collaborate in real-time. All from your phone, tablet, or Mac — with end-to-end encrypted cloud sync across every device. CORE FEATURES • SSH & Mosh — Reliable connections, even on flaky networks. Mosh keeps your session alive where SSH drops. • SFTP File Manager — Browse, edit, and transfer remote files with a native file manager experience. • Port Forwarding — Set up local and remote SSH tunnels in seconds. • Storm AI (Pro) — An AI agent that plans, executes, and completes terminal tasks for you. Not a chatbot — a copilot that actually runs commands. • Real-Time Collaboration — Invite teammates into your live terminal session. Debug together, resolve faster. • Kubernetes — Sync kubeconfigs, switch clusters, manage pods with AI-assisted workflows. • Post-Quantum Cryptography — One-tap switch to PQC key exchange. Protect your connections against future quantum threats today. • Connection Multiplexing — Reuse TCP connections. New sessions open instantly as additional channels. • Hardware Security Keys — FIDO2 / YubiKey authentication via ed25519-sk and ecdsa-sk. • 1Password Integration — Pull credentials directly from your vault. SECURITY FIRST Zero-knowledge architecture. Your data is end-to-end encrypted before it ever leaves your device. Encryption keys stay on your device — we never see them. Encryption is fully open-sourced for transparency. SYNC EVERYTHING Sessions, keys, snippets, and configurations sync across major OS. Pick up exactly where you left off. PRO UNLOCKS • Background connection persistence • Biometric app lock • Server performance monitoring dashboard • Full Storm AI access • Cloud sync --- Tempest is built by engineers, for engineers.

Shellter is an SSH, SFTP and FTP client that keeps everything on your phone. There is no account to create, nothing syncs, and the app sends no telemetry. It opens connections to the servers you type in, and makes no other network request. That is the whole product. A REAL TERMINAL — An interactive shell rendered with xterm, not a toy console. It follows the keyboard, resizes the remote PTY when you rotate the phone, and keeps 10,000 lines of scrollback FILES WITHOUT A SECOND LOGIN — Browse, upload, download, rename, delete and create folders over SFTP or FTP. Open the file browser from inside a live SSH session and it reuses that connection instead of opening another one. A download never silently overwrites a file you already have. HOST KEYS, PINNED AND CHECKED — The server's host key is pinned the first time you connect and compared on every reconnect. If it does not match, the connection stops BEFORE authentication — your password is never sent to a server that failed the check. WHERE YOUR SECRETS LIVE — Passwords and private keys go into the iOS Keychain, hardware-backed where supported, stored "this device only" so they cannot be restored onto another phone. HONEST ABOUT PROTOCOLS — SSH and SFTP are verified by host-key pinning. FTPS is encrypted but does not verify the certificate. FTP is cleartext. Prefer SFTP.
