Questions and answers
What does a player need to run the game?
A browser with WebGPU and multi-threaded WebAssembly. The game opens in a tab, so a player installs nothing.
Do I need to know how to code?
No. You describe the game and the agent writes it. A world is Luau code and data, so you can open anything the agent wrote, read it and change it yourself.
Can other people play what I make?
Yes. Publish it and the world gets its own page, where anyone you share it with can play it in a browser. You choose whether it is public, unlisted or private.
What do credits pay for?
The agent's work. Each turn it takes is charged for the model work it does, and so is generating images and 3D models. Building by hand in the engine costs no credits.
The Free plan includes 200 credits a day, which reset at midnight UTC. Paid plans start at $20 a month and add 4,000 credits a month. See plans and prices
