The 3D game engine where your coding agent builds the game you imagine, and ships it.
Your agent sees, runs, tests and replays the game as it builds. Multiplayer, hosting, accounts, saves and selling are built in, so there is nothing for you to run, and hosting is free. Players open a link and play, and you keep 70 percent of net sales.
The docs
Section titled “The docs”LearnPaste one prompt into your coding agent. It sets up the platform and builds your game with you.
EngineScenes, entities, behaviours, UI and graphics, and the tools that run, read and test a game.
PlatformMultiplayer rooms, publishing, the asset library, templates and the license.
GamesGames built on the platform, each with its mechanics and numbers.
Start with one prompt
Section titled “Start with one prompt”Paste this into Claude Code or Codex. You need Node 24.2 or later:
Let's build a game together on Spawnite. Before we talk about what to make, read this first: https://wiki.spawnite.com/learn/agent-checklist/Your agent sets up the tools, asks what game you want, and shows you a version you can play. Building, publishing and hosting are free. A game made here is published and played on Spawnite.
New here?
Section titled “New here?”Is it right for you?Who Spawnite suits, what it costs, what you keep, and what to use if it does not fit.
How your agent works on your gameYour agent runs the game with no window, reads what happened, and finds the moment you marked with F8.
What works and what is comingWhat a game can use, what the engine does not do, the limits, and what is coming next.
For agentsThe setup as numbered steps an agent follows by itself.
