Pocketmux gives you secure, real-time access to your tmux terminal sessions from your device, wherever you are. Whether you're monitoring a long-running build, interacting with an AI coding assistant, or managing a remote server from the couch, Pocketmux keeps your tmux workflow within reach. No VPNs. No open ports. No complicated setup. Just install and setup the free, open-source pmux CLI + Agent on your computer, scan a QR code, and your tmux sessions appear on your phone. - HOW IT WORKS Pocketmux connects your phone directly to your computer using WebRTC peer-to-peer data channels. Terminal data flows between your devices over an encrypted tunnel, the signaling server is just a service which helps your devices find each other. Once connected, the server is out of the picture entirely. 1. Install pmux via Homebrew on your Mac or Linux machine, or WSL 2. Run pmux init to start the background agent 3. Scan the pairing QR code with PocketMux on your phone 4. Access all your tmux sessions instantly Replace tmux with pmux in your workflow. Every tmux command works exactly the same, but now your sessions are accessible from your phone. - PRIVACY BY DESIGN Pocketmux was built from the ground up with a zero-knowledge architecture: * The signaling server NEVER sees your terminal content, session names, commands, or output * All terminal data is end-to-end encrypted with DTLS - Device authentication uses Ed25519 cryptographic key pairs, no passwords, no email accounts, no OAuth - The server stores only the bare minimum needed to facilitate device pairing - The open-source agent and protocol let you verify every claim yourself Your terminal sessions are yours. We don't want to see it, and we built Pocketmux so we can't. - BUILT FOR REAL TERMINAL WORK Not a gimmick or a read-only viewer. A fully interactive terminal client: - Full rendering of colors and cursor positioning, and escape sequences all work correctly - Custom keyboard accessory bar with Ctrl, Alt, Tab, arrow keys, common shortcuts, and customizable inputs optimized for touch - Native session/window/pane navigation, browse your tmux hierarchy as a clean mobile UI, not a compact tiny terminal - One-pane-at-a-time view that makes the most of your screen - Responsive input with minimal latency over direct P2P connections - PERFECT FOR - Checking on long-running builds, deploys, or CI jobs - Answering prompts from AI coding assistants (Claude, Copilot, Cursor) while away from your desk - Tailing logs and monitoring services - Quick SSH hops through your tmux session - Running commands on your home server from anywhere - Any time you think "I wish I could just check my terminal real quick" - OPEN SOURCE CORE The pmux CLI agent, wire protocol, signaling server, and shared libraries are all free and open source under the MIT license. Inspect the code, contribute improvements, or self-host the entire stack. Pocketmux earns your trust through transparency, not promises. - SUBSCRIPTION Pocketmux is available for a subscription fee.
