a sentence.
Meet GigaEngine. Turn the idea in your head into a playable 2D or 3D game. Right here in Gensprite.
The next chapter of Gensprite
From “what if”
to “one more round.”
You already bring characters to life.
Next, give them a world to play in.

Describe your game.
A dungeon crawler, a tiny racing world, something nobody has played before. Start with the idea in your head.
- 02
Watch it take shape.
An agent brings the art, scenes and game logic together with GigaEngine, and checks that it runs. Watch every step.
- 03
Go from prompt to play.
Play it right in your browser. Then keep building in chat: change the feel, grow the world, and download it.

A few things
to know.
What is GigaEngine?
GigaEngine is our custom game engine, with 2D and 3D rendering, physics, animation, audio and gameplay scripting. In Gensprite an agent uses it to build the game you describe.
What do I get for free?
One game from one prompt, to play in your browser. Sign in with your email, Google or GitHub; no card needed.
How do I keep building it?
Buy any credit pack once. Then you can keep changing your games in chat and make new ones. You pay for what each prompt uses: the agent's model time and the art it makes. There is no fixed price: the agent works until the game is done and stops early only if your credits run out, and a prompt that ends without a playable build costs nothing.
Can I download my game?
Yes, with the Game pack: one purchase that unlocks downloads for every game on your account and comes with credits for more prompts. You get a web build you can upload to itch.io or any web host, and the GigaEngine project itself.
What do I need to play?
A browser with WebGPU: recent Chrome, Edge or Safari on a computer. Games run in a sandboxed frame on the page.
Your imagination. Our engine.
