You've played thousands of games.
Time to make one.

Playing, watching, and sharing any game is always free. Building your own runs on a plan, from $20/mo, which is enough to ship a handful of real games a month.

Not at all. Just describe what you want in plain English, like 'make a platformer where I collect coins' or 'create a space shooter with power-ups', and Star handles the rest.

Just a few minutes. Describe your idea, and Star generates a playable game. You can then refine it with follow-up prompts like 'add enemies' or 'make it faster'.

Every game gets a unique URL that works everywhere: Twitter, Discord, iMessage, or any browser. Games work on desktop and mobile with no downloads required.

Claude and ChatGPT write code, and for a single-file prototype they're fine. Star runs everything around the game: multiplayer rooms hosted on our servers, leaderboards, touch and gamepad controls, instant hosting at a shareable link, and exports to itch.io or a Windows .exe. Star's agent has also shipped thousands of games, so it gets gamedev-specific things right (game feel, collision, difficulty) that general tools fumble on the first try.

Keep them. Star does the parts they can't: hosted multiplayer, live leaderboards, mobile-ready controls, and a link your friends can play immediately. Several of our heaviest users run Claude Code daily and still build their games on Star, because the agent is tuned on thousands of real games and the infrastructure is already running.

Yes. Say 'make it multiplayer' and Star hosts the rooms on our servers. No backend setup, no netcode, and the match keeps running when the host closes their tab.

Fast is great for quick games and iterations. Pro builds more complex, polished games with better gameplay and visuals. Ultra is our most capable model, for your most ambitious games. Bigger models draw more of your monthly usage per change, so most creators iterate on Fast and bring in Pro or Ultra for the heavy lifting.
