Made a game in any engine? Publish it on Spawn. Real players try it the day it goes up.
any engine
A web export of your game works: Unity, Godot, Phaser, three.js, Construct, GameMaker, or plain HTML and JavaScript. Players open it from a link, on a computer or a phone, with no install. Its page has Spawn's chat, reviews and likes around it, and it is marked as made outside Spawn.
real players
Spawn checks your game before players see it. Then real players play it the day it is listed. You see how many played, what they said, and how fast your game loads beside a game made on Spawn.
The check plays your game on a computer and on a phone. It checks that the game loads, does not crash, answers its controls, has a real goal, is your own work, and keeps to Spawn's content rules. If it does not pass, the check tells you why. Fix it and send it again.
publish with your coding agent
Copy the prompt and paste it into Claude Code or Codex, in the folder with your game. Your agent makes the web export if your game needs one, uploads it, and publishes it as you. The prompt holds a one-time code that lets your agent publish as you, so keep it to yourself.
the 30-day offer
For 30 days, Spawn pays creators who bring a game they already published somewhere else.
100 slots
$100, once per creator, for the first 100 creators whose game qualifies.
Your game was live on another site (itch.io, Wavedash, CrazyGames, Poki, Newgrounds and others) on or before the day we announce the offer.
It passes Spawn's check.
You prove the other listing is yours: put the code Spawn gives you in its description, or have the same handle there as on Spawn.
We pay within a week of your game qualifying, through Stripe, to a payout account Stripe accepts. Set up payouts on Spawn to receive it.
Claims are open for 30 days from the announcement.
Spawn staff and test accounts are not paid.
make it native
Many creators rebuild their games on Spawn with Savi, the AI you build with in every Spawn game, and she does it well. A native game gets everything Spawn has:
Savi. Tell her what to change, and she changes it while you play.
Multiplayer from the first moment. Anyone who opens your game plays in the same world as everyone there, and you write no networking code.
Phones at Spawn's speed. Your game opens fast on a phone, with touch controls made from its own controls.
Saves on their own. Your players' progress keeps without a save system of yours.
Earning. Spawn's money and payouts work in native games.
Change it while people play. You build in your own copy while players keep the version you published. Each change is a version, and Savi can take the game back to any of them.
Your game keeps its address, its likes, its reviews and its players when it goes native.
what you need
A computer with your game's source: its code and its art (pictures, models and sounds).
A coding agent on that computer, like Claude Code or Codex. It brings your files in.
A game made with three.js, Babylon, Phaser, Unity or Godot can come across, 2D or 3D, as long as you have its source.
In Savi's chat, type /agent. You get a one-time key for this game. It works for ten minutes, so have your coding agent open first.
Paste the key into your coding agent. It joins this game as a builder, so keep the key to yourself. Tell it to bring your game's code and art into the new game as they are.
Ask Savi, or your agent, to build it in Spawn as the same game. Then play it, and tell them what feels different.
what to leave behind
Your multiplayer code. Don't have your agent rebuild it. Every Spawn game is multiplayer on its own, so leave out your game's servers, rooms, lag prediction and player syncing. Spawn carries the players.
Your old engine and libraries. Your game is adapted to Spawn's engine. Don't ask for three.js, Phaser, Godot or another library to come along inside it. A game that brings its own engine can stop working.
Your own servers and database. Spawn runs your game's servers and keeps your players' progress. A game that depends on a server of yours can stop working, and we can't feature it.
How to code it. Tell Savi what the game is and how it plays. She picks how to build it in Spawn.
what comes across
Your game's rules, levels, controls, screens and art. Your pictures, models and sounds come across as they are. Your code is rewritten to run on Spawn's engine.
If something plays differently, tell Savi what you see, and she works on it in the game.
