There is no download here yet. The Mac app is being built and is not signed or notarised, so macOS would refuse to open it. We would rather have nothing on this page than a file that does not open.
What it will be: a beafk window on the Mac you are sitting at, running your agents on that same Mac — it installs the machine, pairs it, and opens it over loopback, so the Mac itself needs no private network. One universal .dmg for Apple silicon and Intel, with no version to choose.
All of that already works on a Mac without the app, from one line in Terminal. Your first machine walks through it, and Pricing is what it costs.
