Questions and answers
Short answers to what people ask before they connect their AI. Each answer links to the page with the details.
Do I need an API key?#
No. You connect KUMODeck to your AI by signing in in your browser: you sign in, choose what your AI may do and press Allow. Your AI never sees a secret key, and you never paste one into a file or the conversation. If your app needs a key from another service, you type it into a small KUMODeck page, not the conversation. See Deploy a game from Claude Code without API keys.
Is it free?#
No. There is no free tier. You pay KUMODeck's usage fee for the parts you use, at cost, from a prepaid balance, from the first request. An invite code adds $5 of invite credit for usage fees. Prices and worked examples are on Pricing.
Do I need an invite code?#
No. Anyone can sign up. An invite code is optional: it adds credit to your balance. Without one, your balance starts at $0, and creating, publishing and AI features wait until you add funds or enter an invite code. You can enter a code after signing up too, under Billing on the dashboard or with kumodeck billing redeem <code>. See Pricing.
Which AI can I use?#
AI agents that support MCP, such as Claude Code, Codex and Cursor, and the Claude, ChatGPT and Muse apps in a browser. AI agents that run commands can also use the KUMODeck CLI with one pasted line. Start here has the steps for each.
Do I need to know how to code?#
No. You ask your AI in plain words, for example "Put this game online" or "Make it playable online", and it does the work in your project. The pages under Talk to your AI agent list requests you can copy.
Can my AI publish without me?#
It can put a test version online. Putting it on the address everyone can open always waits for you: you press Publish on a KUMODeck page in your browser. Deleting asks you first too. Creating your account and signing in are always done by you.
What happens to my game if I stop paying?#
Usage comes out of your prepaid balance, so nothing runs on money you did not put in. You get a low-balance email first. If the balance reaches $0, everything that is billed pauses, including your game for its players, who see a neutral message without the KUMODeck name. Your dashboard and your data stay reachable, and everything resumes on its own when you top up. Automatic top-up keeps a game from pausing. See Prepaid balance.
What happens if I close my account?#
You delete your projects first, then close the account on the dashboard or with kumodeck account close in your own terminal. It cannot be reopened. The unused part of what you added by card is refunded to that card after the month's usage is final; invite credit is not returned. See Closing your account.
Who owns what I make?#
You do. The apps and games you make, and the code, images and data you upload, belong to you; KUMODeck takes no rights to them. See Terms of service.
What if my game suddenly gets a lot of players?#
There is no free-tier limit that switches it off. It keeps running and is billed at cost from your balance. As an estimate on Pricing, a game with 100,000 plays in a month costs about $1.98 at list price. Turn on automatic top-up so it never pauses.
Can I use my own domain?#
Yes. Your own domain costs $0.11 a month per domain, taken from your prepaid balance; you still pay for the domain where you bought it. See Custom domains.
Will my players see the KUMODeck name?#
No. Hosted apps are served on your app's own address or your own domain, with no KUMODeck branding in front of your users.
Can I host a Unity or Godot game?#
Yes. Export it for the web and put the whole folder online; Unity's compressed builds work without server settings. See Unity games and Godot games.
Where does my game run?#
On Cloudflare. You do not need a Cloudflare account. The limits that come from Cloudflare are listed on Limits.
