Mastward

Run Claude Code, Gemini and any CLI on your own computer — from your phone. Pair with a QR code, keep working from anywhere. Your code never leaves your machine.

Mastward turns your phone into a remote control for your own computer's terminal — built for running AI coding agents like Claude Code and Gemini CLI from anywhere.

YOUR COMPUTER, IN YOUR POCKET Start a job on your Mac, walk away, and keep steering it from the couch, the car or the job site. Mastward connects straight to a small engine you install on your own computer. No cloud in the middle, no account to create.

PAIR IN SECONDS Open the engine on your computer, scan the QR code with your phone — you're connected.

MADE FOR AI CODING AGENTS • Launch and switch between Claude Code, Gemini and other CLI tools with one tap • Sessions keep running when you close the app — reconnect and your job is still going • On-screen key bar: Esc, Tab, Ctrl, arrows, and a true EXIT button for stubborn terminal apps

A REAL TERMINAL • Full terminal emulation with scrollback • Scripts library: your commands are captured automatically — save the good ones, re-run them with a tap • Secret masking: passwords and keys are hidden in the stream

PRIVATE BY DESIGN • Everything runs on your own computer — your code and data never touch anyone's servers • No analytics, no tracking, no sign-up • Works over your own network or your own VPN (e.g. Tailscale)

WHAT YOU NEED The free Mastward engine running on your own Mac. Your phone connects to it directly — nothing else in between.
