Tell your coding agent “Publish my game to cassette.gg”. It shows you a code to approve, writes the store page and uploads the build. The game plays at its own link, cassette.gg/g/your-game, which you can share at once. It joins the store after the automated checks and a review. ### Is there a site for vibe-coded games? cassette.gg publishes them. A vibe-coded game goes through the same automated checks and review as every other game, and sits in the store next to them. ### Are games made with AI allowed? Yes. Your agent says how AI was used in the store details: for code, art, audio, music, voice and text. The store page doesn’t show it. ### I made my game in ChatGPT, Claude, Gemini, Lovable or Replit. How do I put it online? Save the game’s files in a folder, open a coding agent there (Claude Code, GitHub Copilot, Codex, Cursor, Antigravity, OpenCode or Hermes) and tell it “Publish my game to cassette.gg”. An agent does the publishing: there is no upload form. The game has to run in a browser. ### Can I publish a single-file HTML game? Yes. The game can be one index.html. Your agent adds Cassette’s script, makes the screenshots and box art, and uploads it all as one zip, up to 500 MB. ### What does it cost? Nothing to publish or host. If you sell the game, your share of a sale is 90% after tax and payment fees: on a $10 game bought in Spain, $6.98. ### Can I sell my game? Yes, for $0.99 to $200.00 with tax included, in US dollars, or keep it free. Cassette sells it by card through Stripe, charges the tax and handles refunds. A paid game can open with a free demo. You withdraw your balance up to once a month, from $50. ### Does my game get saves, leaderboards and multiplayer? Yes, through one script your agent adds: cloud saves of 10 MiB per player per game, sign-in with email, Google or Apple, and up to 10,000 leaderboards and 10,000 achievements. Multiplayer rooms hold up to 8 players, who join by a five-character code, an invite link or quick match, and you run no server. ### Do I need to write code or install anything? No. Your agent does the work, and there is no package to install. You approve one code in your browser, and from then on the agent’s key publishes to your studio and nothing else. ### Does it work with cloud agents? Yes. Cloud agents publish the same way. Most block unknown sites until told, so add cassette.gg to the agent’s allowed domains. ### Who owns the game? You do. You give Cassette a non-exclusive licence to host, sell and promote it, and keep all rights. ## Made it with a particular tool? - [Publish a game made with Claude Code](https://cassette.gg/made-with-ai/claude-code.md) - [Publish a game made with Codex](https://cassette.gg/made-with-ai/codex.md) - [Publish a game made with Cursor](https://cassette.gg/made-with-ai/cursor.md) - [Publish a game made with ChatGPT](https://cassette.gg/made-with-ai/chatgpt.md) - [Publish a game made with Lovable](https://cassette.gg/made-with-ai/lovable.md) - [Publish a game made with Replit](https://cassette.gg/made-with-ai/replit.md) - [Publish a game made with Bolt](https://cassette.gg/made-with-ai/bolt.md) - [Publish a game made with v0](https://cassette.gg/made-with-ai/v0.md) ## Add to your game - [How do I add leaderboards to my AI game?](https://cassette.gg/how-to/leaderboards.md) - [How do I add usernames and player sign-in to my AI game?](https://cassette.gg/how-to/usernames-and-sign-in.md) - [How do I add achievements or trophies to my AI game?](https://cassette.gg/how-to/achievements.md) - [How do I add cloud saves to my AI game?](https://cassette.gg/how-to/cloud-saves.md) - [How do I add multiplayer to my AI game?](https://cassette.gg/how-to/multiplayer.md) - [How do I sell my AI game?](https://cassette.gg/how-to/sell-your-game.md) - [How do I get paid for my AI game?](https://cassette.gg/how-to/get-paid.md) ## Fix it - [Why doesn’t my AI game save between visits?](https://cassette.gg/fix/game-doesnt-save.md) - [Why is my AI game broken on phones?](https://cassette.gg/fix/broken-on-phones.md) - [Why is there no sound in my AI game on iPhone?](https://cassette.gg/fix/no-sound-on-iphone.md) - [How do I make my AI game go full screen?](https://cassette.gg/fix/no-fullscreen.md) - [How do I give players names in my AI game?](https://cassette.gg/fix/players-need-names.md) - [My AI game is too big to upload.
