Playbeam for the desktop

Your machine. Your subscription.

The studio runs on your own computer — driven by the AI subscription you already pay for, with your files and your terminal in reach.

Builds

Every build here is the same studio. Only the machine changes.

There is nothing here to download yet.

The desktop app is built and it runs. What is missing is a file this page can hand you — either your machine has no build yet, or this server has not been given one.

Builds are cut per machine, and not every machine has one yet — each build below says what it is waiting on.
Windows needs an Authenticode certificate, or SmartScreen warns every person who runs the installer until the download builds a reputation.
This page grows a download button when there is a file behind it, and not before.

Not built yet. The Intel image is currently cut on an Apple silicon Mac, which leaves an Apple silicon binary inside it — so it would install and then fail to start.

Not built yet — the installer has to be produced on Windows. It will also need an Authenticode certificate, without which SmartScreen warns every person who runs it until the download earns a reputation.

You need a computer you can install software on. macOS or Windows. There is no iPhone, iPad or Android build — the app runs a server and drives command-line programs, neither of which a phone will allow.

You can build it yourself today

Clone the repository, run pnpm install, then the command below. It leaves a Playbeam app in apps/desktop/release that you can open straight away — it builds unsigned, which is fine on a machine you own and control.

pnpm --filter @gamestudio/desktop package

First launch

On a Mac it opens like any app. Windows asks once — the installer has no certificate yet.

macOS

Open the disk image and drag Playbeam into Applications.
Open Playbeam. It is notarized, so it opens like any app.

macOS may take a moment to verify the download the first time.

Windows

Click More info.
Click Run anyway.

Before you install

A Mac or a PC: macOS 11 or later, or Windows 10 or later, 64-bit.
An AI subscription, or a key: Sign in to Claude Code, Codex or Antigravity in your terminal and the studio uses that session — no key is typed, seen or stored. Pasting an API key works too.
Nothing else: The studio, its server and its runtime are all inside the app. There is no Node, npm or repository checkout to set up first.

What you get

Who pays for the AI: You do — with the Claude, ChatGPT or Google subscription you already pay for, or your own API key.
What the agent can reach: Your scene, the asset libraries and the running game — plus reading, editing and running files on your own machine.
Getting started: Install it, then sign in to your provider once.

What it does on your machine

The server listens on 127.0.0.1 only. Nothing else on your network can reach it.
The window that renders games is sandboxed, with no privileged bridge into your system.
Links to anywhere else open in your real browser, where you can see the address.
Your projects are stored in your account’s application-data folder, so an update replaces the app and never your work.

Your machine. Your subscription.
