# How do I publish a game I made with Cursor?

Ask Cursor's agent to publish your game on TinyBulb. Because it can run commands, it reads TinyBulb's instructions, packages the game with a cover, an icon and a screenshot, uploads it, and opens a link in your browser where you play the game and publish it with one click. It's free, and there's no account, API key or hosting to set up first.

Say this to your coding agent:

> Publish my game on TinyBulb. The instructions are at https://tinybulb.com/publish.md

## What happens

1. The agent checks the game against TinyBulb's rules and fixes what's needed, such as making the layout work on phones.
2. It uploads the game. If anything doesn't pass, TinyBulb tells it exactly what to fix, and it tries again.
3. Your browser opens on your game's page, exactly as players will see it. Play it, then tap **Publish** and sign in with Google.

The same prompt works in any agent that can run commands, like Claude Code or Codex.

## What kind of game works

Any browser game: HTML and JavaScript, on a canvas or with a library like Phaser, three.js or PixiJS, up to 100 MB. Everything it loads goes in its folder, because games on TinyBulb run without network access.
