Take it with you. Every screen.

One account, three windows onto the same possessed hosts: the companion on your desktop, the app in your pocket, the browser anywhere. The daemon never leaves your machine — these only look in on it.

And the daemon itself

Possess a machine with one line.

The apps are windows; this is the thing they look at. Run one line on the machine you want to possess — never on the phone — and it downloads the matching prebuilt daemon, then starts it for your account. Then the pairing ceremony: consensual, auditable, revocable.

SPAWN D starts with a LaunchAgent or user systemd service, depending on the host.

Where it can run

macOS

Downloads a Darwin build for Apple Silicon or Intel, then starts a LaunchAgent.

Linux

Downloads an x86_64 or arm64 Linux build, then starts user systemd when available.

Windows

Downloads the x86_64 Windows build, then registers SPAWN D as a scheduled task at sign-in.

Remote hosts

SSH into the machine that should run agents, then run the same command there.

Prebuilt-only smoke test

Prove the hosted binary path.

Use this when you want to prove the hosted binary path works and fail instead of building from source.
