Online game maker FAQ
Do I need to download anything to make games?
No. Rosebud runs entirely in your browser — the engine, editor, and asset tools load like a webpage. There is no installer, no SDK, and nothing to update.
Does an online game maker work on a Chromebook or tablet?
Yes. Anything with a modern browser works — Windows, Mac, Linux, Chromebooks, and tablets. Projects are saved in the cloud, so you can switch devices mid-build.
How does it compare to downloadable engines like Unity or Unreal?
You still get the core of a real engine — a code editor, an asset manager, and a live build — plus an AI-first approach to coding if you choose to use it. Creators on Rosebud have produced high-quality games and launched them on Steam and Epic Games, the same way traditional indie devs would with Unity or Unreal, but with the speed that comes from AI assistance.
Do players have to download my game?
No — publishing gives you a link. Anyone who opens it plays instantly in their browser, on desktop or mobile.
Is it really free?
Yes — making and playing games is free. Paid plans add more credits, bigger projects, and commercial rights with 100% of profits yours.
Can I make a game without coding?
Yes. Templates, remixing, and plain-language editing get you to a finished game without writing code. If you do code, the JavaScript is yours to open and edit.
