Guides / Host a game
Host a game you made with Claude, free
Made a browser game with Claude, ChatGPT, Cursor or another AI tool? Put it online free at yourname.guises.site, so anyone can play it from a link. Works with plain HTML5 canvas games and engines like Phaser, Three.js, PixiJS, Kaboom and p5.js.
Make the game as web files
Ask your AI tool for a game that runs in the browser: an index.html with its JavaScript, images and sounds next to it. Engines like Phaser, Three.js, PixiJS, Kaboom and p5.js work, from a CDN or bundled with Vite. Models, textures, maps and audio files are fine.
Create a free hosting spot
Sign in at guises.ai/app/host and choose a name, like space-run. It becomes space-run.guises.site. Copy the prompt it shows: it holds a private upload key for that site.
Let your agent upload it
Paste the prompt into Claude Code, Cursor, Codex or another coding agent in the game’s folder. It zips the game, uploads it and tells you the link. With no coding agent, zip the folder’s contents and upload it with the curl line in the prompt.
Share it and update it
Send the link to anyone: it plays in the browser, on phones too. To update, ask your agent for the change and to ship it again. Earlier versions can be brought back from the Host page.
Good to know
- Keep it static: high scores saved in the browser work; a server-side leaderboard doesn’t.
- Limits: 25 MB zipped, 900 files, 25 MB per file.
- Never include secret API keys in the game: everything uploaded is public.
- Your game also opens at the shorter yourname.guises.ai, unless you have published a page under that name.
- A live example: games.guises.ai, seven small phone games in one site of 37 files and about 90 KB.
Questions
Is hosting a game really free?
Yes. Every account can host one site free, for as long as you like. Pro hosts up to three.
Which game engines work?
Anything that runs in a browser from static files: plain canvas or WebGL, Phaser, Three.js, PixiJS, Kaboom, p5.js, Babylon.js, and Unity or Godot web builds within the size limits.
Can people play it on their phone?
Yes, if the game handles touch. The link opens in any phone browser.
