Make your own game

Any web game works: one HTML file, Phaser, Unity or Godot web builds. Publish it, share the link with friends, and send it to the catalog when it is ready.

1. Ask ChatGPT or Claude

Works from your phone. Add AfterPrompt as a custom connector (MCP) with this address, sign in, and allow “Create, publish and list web games”.

https://afterprompt.games/mcp

Then ask for a game, for example:

Make a small web game about paper planes in a single index.html, mobile-friendly, no external scripts. Publish it to AfterPrompt with create_game and publish_version, write its page with update_game_page, add screenshots with capture_screenshots, and give me the link.

2. Use Claude Code or Codex

Install the AfterPrompt plugin. It adds the afterprompt command and a skill that publishes a game folder; the first time, you approve the sign-in in your browser or with a short code on your phone.

/plugin marketplace add inchidev/afterprompt-plugins
/plugin install afterprompt@inchidev

Make a web game in ./my-game and publish it to AfterPrompt with the afterprompt-publish skill, with its page: a short and a full description and screenshots.

3. Upload a built game

Drop the folder with index.html into My games. Unity: build for WebGL with compression Disabled, or with Decompression Fallback. Godot: export for Web with Thread Support off.

Open My games

What a game needs

index.html at the top of the folder, and only relative links inside (game.js, not /game.js).
Everything inside the folder: scripts and fonts from other sites do not load.
Up to 25 MB per file and 100 MB per game.
Optional: load __afterprompt/sdk.js to know who is playing.
Your own work only. The catalog shows games we checked.
