For developers
Your AI agent publishes the game.One prompt. Nothing to install.
GameArter has a new, much simpler way to publish browser games. One open standard describes everything a game needs.
Your agent reads it and prepares the game. You upload the result and the game gets the GameArter player on its own.
The whole process
From a game folder to a published game
Create the game
Sign up or sign in at studio.gamearter.com and add the game as a new project. That gives you its slug, which the agent will ask for.
Paste one prompt
Your agent reads the standard, writes the texts and the images brief and validates the package.
Upload the folder
Drop the finished folder into your account. Every game is reviewed before it goes live.
Player included
No API key
Nothing to install
Three steps
Let your AI agent publish the game
First version · in testing
GameArter defines everything a game needs for publishing in one standard – texts, images, categories and the build. Your agent reads it, prepares the package and validates it, so you never have to ask about formats.
The publishing standard, its tools and the player are first versions and may still change. Found a bug or have an idea? Let us know via the contact page.
Pick how your agent connects
Both ways give the agent the same standard and the same tools. You only need one.
- 1
Paste the prompt
Open your game folder in Claude Code, Cursor, Codex or any other coding agent and paste the prompt. Nothing to install, the agent needs no login or API key. Create the game in your GameArter account first – the agent will ask you for its slug.
Download the full text of https://www.gamearter.com/api/publishing/standard (for example with curl; in Windows PowerShell use curl.exe) and read the whole file, not a summary. Then prepare the game in this folder for GameArter. Follow the standard exactly and validate the package before you finish.
- 2
The agent prepares the game
It reads the publishing standard, picks categories, writes the texts and images brief and builds the package.
- 3
Upload the folder
The agent validates the manifest, texts and images until everything passes. You drop the finished folder into your GameArter account – the agent never needs your login. Every game is reviewed before it goes live.
GameArter player – works out of the box
Every hosted HTML5 game gets a lightweight player with a small G button. The game runs as usual, the player stays out of its way.
- Works out of the box – no init code, no configuration in the game
- Back, Fullscreen and Powered by GameArter in one small G button
- Isolated in Shadow DOM – no global styles, clicks never reach the game
- Built from modules – ads, analytics and leaderboards will follow, switched on in your dashboard
Most settings will be managed in your dashboard, outside the game. Only some modules, such as ads, will need a call at the right moments in the game.
Optional: choose where the button sits
<div id="gamearter-toolbar"></div>Put it next to your own menu, ideally top left. The player sizes it to 44×44 px and follows it. Without it, the button sits at the screen edge.

Why it is this simple
Designed for agents, safe for you
One standard
A single document says exactly what a game needs: texts, images, categories and the build. Your agent never has to guess a format.
Open tools
Categories and validation work over plain HTTP or as an MCP server. They are public and read-only.
Your login stays yours
The agent needs no password and no token. You upload the finished folder yourself.
Reviewed before live
Every game is checked by GameArter before it is published, so nothing goes out by accident.
