How do I publish a game I made with Codex?
Open Codex in your game's folder and ask it to publish the game on TinyBulb. 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
- Codex checks the game against TinyBulb's rules and fixes what's needed, such as making the layout work on phones.
- It uploads the game. Codex runs commands without network access by default, so it asks you to approve the upload.
- If anything doesn't pass, TinyBulb tells Codex exactly what to fix, and it tries again.
- Your browser opens on your game's page, exactly as players will see it. Play it, then tap Publish and sign in with Google.
Your game is then listed on TinyBulb's home page, where players find it, and My games shows its plays, players and play time.
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.
Make it better first
TinyBulb's game skill takes Codex through phone controls, loading screens, game feel and testing at phone sizes before it publishes. Ask Codex to install it with npx skills add https://tinybulb.com.
