Claude Code, Codex, Gemini, your local models — run them on your own computer and steer them from your phone, tablet or laptop. Your source code never leaves your infrastructure. No vendor lock-in. No cloud relay. Own it, don't rent it.
The phone-controls-the-agent pattern Anthropic & OpenAI just shipped — but vendor-neutral, and on hardware you own.
Anthropic and OpenAI just proved you want to drive your coding agent from your phone. Mastward does it without locking you to one vendor — or to anyone's cloud.
Claude Code, Codex, Gemini, Aider, your local Ollama models — launch, switch and supervise them all from one place. Not tied to a single vendor's app.
The agent runs on your machine; your repository never touches a vendor's servers. The compliance answer cloud agents can't give.
Connections go device-to-machine over your own network (e.g. Tailscale). There is no server of ours in the path.
No sign-up, no telemetry, nothing phones home. Access is by per-device key you control — revoke a lost device instantly.
Sessions keep running when you close the lid or drop signal — reattach with full scrollback, even after a restart.
The built-in doctor checks everything on first launch and auto-repairs what it safely can. No terminal gymnastics to install.
Every command you run is captured and one-tap reusable — turn anything you do into a saved script.
No subscription. A one-time licence validates offline against a key — it never checks in with us.
No config files, no command line. Download, open, done — the app starts its own engine locally and asks only for the permissions it needs.
Grab the Mac app below and drag it to Applications. First launch starts everything for you.
macOS asks once for the access it needs (local network). The app explains why, in plain words.
Scan a QR to pair a device. If anything's off, the auto-doctor detects and fixes it — you don't touch a terminal.
One web core, every device. Pick your platform.
