About this app

Tempest is a powerful SSH, RDP, VNC, S3, WebDAV, SFTP, FTP, Telnet, Serial, RCON, and Mosh client for Android — built for developers, sysadmins, and DevOps engineers who manage servers on the go.

Whether you need a secure terminal, an SFTP file manager, Remote Desktop Manager, SSH port forwarding, or Kubernetes cluster management, Tempest gives you a complete server administration toolkit in one app.

SSH & MOSH TERMINAL

Connect to any remote server with full SSH2 support. Mosh (Mobile Shell) keeps your session alive on unreliable mobile networks and high-latency connections — no more dropped sessions when switching between Wi-Fi and cellular. Tempest's terminal supports custom fonts, themes, and a developer-friendly function key bar.

SFTP FILE MANAGER

Browse, view, edit, and transfer remote files with a built-in SFTP file manager. Manage your server's filesystem as easily as local files. Supports bookmarks, batch transfers, and a dedicated task manager for large file operations.

SSH PORT FORWARDING & TUNNELS

Set up local and remote port forwarding over encrypted SSH tunnels. Access internal services, databases, and web interfaces securely from your Android device — no VPN required.

STORM AI — YOUR TERMINAL COPILOT

Storm AI is not a chatbot. It's an AI agent (Pro) that plans, runs, and completes terminal tasks for you. Use it to diagnose network issues, craft SQL queries, parse logs, generate commands, and automate server maintenance. Powered by the latest AI models with support for custom model configuration.

REAL-TIME COLLABORATION

Invite teammates into your live terminal session for real-time collaboration. Troubleshoot together, pair on server tasks, and resolve incidents faster — all within the same encrypted session.

KUBERNETES MANAGEMENT

Sync kubeconfigs, manage multiple Kubernetes clusters in isolated tabs, and use AI-assisted workflows to handle pods, deployments, and services. A complete K8s management experience on mobile.

POST-QUANTUM CRYPTOGRAPHY (PQC)

Protect your SSH connections against future quantum computing threats. Tempest supports post-quantum key exchange algorithms — switch between PQC and classic SSH encryption with one tap.

HARDWARE SECURITY KEY AUTHENTICATION

Authenticate with FIDO2 hardware security keys (YubiKey) via NFC. Supports ed25519-sk and ecdsa-sk key types for the highest level of SSH authentication security.

CONNECTION MULTIPLEXING

Reuse existing TCP connections — new SSH sessions open instantly as additional channels on the same connection. Faster, more efficient, fewer handshakes.

END-TO-END ENCRYPTED CLOUD SYNC

Your sessions, keys, snippets, and server configurations are encrypted on your device before syncing to the cloud. Zero-knowledge architecture means your encryption keys never leave your device. Sync securely across Android, iOS, macOS, Windows, and Linux. Open-sourced encryption for full transparency.

Ratings and reviews

If you manage multiple servers and work across different operating systems, Tempest is a must-have. The cross-sync functionality works perfectly, making my terminal setups consistent whether I'm on my phone or my laptop. It’s stable, supports all the major platforms (Android, iPhone, Win, Mac, Linux), and has a very responsive terminal. 5 stars!

This would be a 5 star review, but for 2 points. A: locking mosh behind a paywall is absurd. Literally all the app has to do is send MOsh instead of Ssh. B: it disconnects from the remote server when you turn off your screen. Makes it utterly useless. It's really a shame because it really shines over termius and termux, but those 2 things are total dealbreakers for me

actually the only usable app I could find, easy to use and overall works fine. loving it
