About Game Builder Agent
Game Builder Agent exists for one moment: the one where you can explain a game to a friend in a paragraph but have no way to make it. Type that paragraph here and a playable version appears in the emulator preview; keep talking and it grows levels, scores, a leaderboard, ads and a second player; when it is fun, it becomes an Android game on real phones.
Why a prompt instead of an editor
Level editors and sprite sheets are great once a game exists. They are a wall before it does. The thing most people actually have is a mechanic in their head — "hold to charge, release to jump, the gap widens" — and the shortest path from that sentence to a thumb on glass is to let an AI agent write the loop, the controls and the screens, show the result, and change it on request. That is the whole product. The code is real React Native for mobile games and real canvas code for browser games, so there is no ceiling you hit later and nothing to migrate away from.
What we say no to
We do not promise iOS builds, 3D engines or asset marketplaces, because the builder does not do those today. We do not run your games on a separate "lite" engine: the game in the preview is the game in the APK. And we do not show ads to you while you are testing — the preview marks ad slots as simulated until the build on your phone uses your own ids.
How the games are built
Mobile games are React Native apps with a requestAnimationFrame loop, touch controls written for phones, and an optional data layer for scores and levels. Browser games draw on a canvas, accept keyboard and pointer input, and publish to a link. Both can join rooms for online play through the built-in realtime relay.
The people
Game Builder Agent is built and run by a small independent team that also makes the agent behind it. Guides on this site are written from what the builder does, with the prompts we actually typed, and updated when the builder changes.
