# Pocketmux Docs > Documentation for pmux, the open-source CLI that provides secure remote tmux access from a phone, and the Pocketmux mobile app (iOS and Android). pmux runs on your computer as a transparent tmux proxy; the app connects directly to it over an end-to-end encrypted, peer-to-peer WebRTC DataChannel. The signaling server is zero-knowledge — it never sees terminal content, session metadata, or activity. Key facts: - The pmux CLI, agent, signaling server, and wire protocol are free and open source (MIT): https://github.com/ShiftinBits - The Pocketmux mobile app is a paid companion: no accounts, no ads, no tracking - Authentication uses device-bound Ed25519 keys — no passwords, OAuth, or email - Device pairing uses a one-time QR code and X25519 key exchange; the pairing secret never touches the server - Terminal data is encrypted end-to-end with DTLS; an encrypted TURN relay is used only as fallback - Availability: United States and Canada (App Store and Google Play) - Publisher: ShiftinBits Inc.
