Common Questions

Yes. Playing and sharing any Star game is free for everyone, and you can start building free with Luna. When you want to keep building, buy a one-time credit pack from $3 or subscribe from $20/month for the best credit rate.
No. Describe what the player does, like 'jump between platforms and collect coins'. Star builds a first version you can play and change with follow-up instructions.
A first version usually takes a few minutes. Bigger ideas can take longer. Play it, then tell Star what to change, like 'add enemies' or 'make it faster'.
Publish your game, then send the link in a message, group chat, or social post. Friends can open it in their browser without installing Star.
No. Anyone can play and share your published games free — no account, no plan. Your friends never pay to play what you build.
Star combines a game editor with hosting, multiplayer rooms, leaderboards, and exports. Build and revise your game here, then send friends a playable link. You can also export to itch.io, Windows, or your own files.
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.
The model picker names them directly. GPT-5.6 Luna is the default — it thinks hard, costs the least per change, and is what free accounts build on. Claude Sonnet is the fastest on small edits; Claude Opus is thorough on bigger builds; Claude Fable is our most capable model, for your most ambitious games; and GPT-5.6 is tuned for code-heavy builds. Bigger models draw more of your monthly usage per change, so most creators iterate on Luna and bring in the Claude models for the heavy lifting.
