by Rosebud AI, Inc.
Browser game maker, in Y Combinator's 2019 batch, where you describe a game to an AI designer and get a playable 2D or 3D web game.
Good for a first playable game tonight with no install and no code, especially for students, teachers and game jams. The free 10,000 weekly credits cover only a handful of AI edits, and selling or exporting a game needs a paid plan, so treat the free tier as a test drive.
A prompted game becomes a link that plays on any phone or desktop browser, in 2D or Three.js 3D, with no install at any step.
Remixable public games and a share link that plays anywhere keep creators on the platform, but games and credits stay on Rosebud's hosting until a Pro plan unlocks code download.
Main trade-off
Free and Indie Dev projects cannot leave Rosebud: code download and the Windows export start at the Pro plan.

Free plan (Newbie): 10,000 credits a week in eligible regions. The four paid plans run from Indie Dev at $15 to Scale at $100 a month; every paid plan also grants 10,000 daily refresh credits on top of its monthly pool, and top-ups can be bought from My Plan.
Rosebud AI is a browser-based AI game maker: you describe a game to Rosie, its AI designer, and it writes the code, art and sound for a playable 2D, Three.js 3D or voxel web game that publishes to a shareable link. Its company page counts more than 2.5 million games made.
Rosie, the AI game designer
Asks a few questions about your idea, then writes the game's code, art and sound; each Rosie edit costs roughly 2,000 credits from your balance.
2D, 3D and voxel web games
Builds 2D games, 3D games on the Three.js library and voxel worlds, including RPGs, platformers, visual novels, puzzles and multiplayer games.
Instant publishing by link
Every game publishes to a rosebud.ai address that plays on desktop and mobile browsers with no install, and can also run as a playable post on X.
Built-in asset generators
Makes sprites, sprite animations, 3D models (about 1,000 credits each), 360-degree skyboxes and sound effects inside the same editor.
Remix any public game
Games on Rosebud Play can be copied and changed as a starting point; paid plans can switch remixing off for their own projects.
Code tab and code download
Indie Dev and higher plans can read and edit the generated code in the browser; Pro and higher can download it and export a Windows build for Steam.
Most users expect these and they are not currently supported.

Proprietary
Newbie is free, Indie Dev is $15 a month, 10x Dev $30, Pro $50 and Scale $100, all in US dollars. The paid plans add 100,000, 300,000, 1,000,000 and 2,000,000 monthly credits on top of 10,000 daily refresh credits. The cost that catches people out is the plan you need for selling: commercial rights start at 10x Dev and code download at Pro.
Yes. The free Newbie plan gives 10,000 credits with no card, refilled every week in eligible regions, and you can create, play, remix and share games. An edit turn with Rosie uses about 2,000 credits, so a week's allowance covers roughly five edits. Free games stay public and remixable and carry Rosebud branding.
Rosebud's pricing FAQ says the 10x Dev plan and above include full commercial rights, and Rosebud takes no commission on your earnings. Putting a game on Steam needs the Pro plan or higher, which adds code download and a Windows build export. Free and Indie Dev games stay on Rosebud's hosting.
Yes. Its 3D game maker builds games on Three.js, a widely used JavaScript library for 3D graphics in the browser, and it also makes voxel worlds. The results are web games, so they suit browser play and quick sharing more than a large console-style 3D project.
Its privacy policy, read on 15 November 2026, says Rosebud turns user content and usage data into anonymised datasets that it may license or sell to research partners and frontier AI labs. It states that no data that could identify you is shared, and that there is currently no opt-out. Paying for a plan does not change this.
Rosebud AI turns a plain-English game idea into a playable web game. You chat with Rosie, its AI game designer, which asks a few questions and then writes the code, art and sound. Rosebud AI, Inc. was founded in 2019 by Lisha Li in San Francisco, went through Y Combinator's Summer 2019 batch, and has been run by CEO Vladimir Glazachev since April 2026.
Everything happens in the browser. Games are standard web games: 2D, 3D built on the Three.js library, or voxel worlds, and each one publishes to a rosebud.ai link that plays on a phone or a desktop with nothing to install. Built-in generators make sprites, sprite animations, 3D models, skyboxes and sound, and any public game on Rosebud Play can be remixed as a starting point. People who code can open the generated code in a browser tab and edit it directly. On 15 November 2026 we opened Rosebud Play without an account and played Silver Street, a community-made 3D car game: after a short loading screen it ran in the browser as a third-person drive with a minimap and on-screen gas, brake and steering buttons.
It suits hobbyists, students and teachers who want a playable prototype in an evening, and game-jam entrants who need to test whether an idea is fun before committing to an engine. Writers use it for visual novels and interactive stories.
It is a weaker fit for anyone who wants to keep iterating on the free plan or wants their project kept off AI-training datasets. A buyer who wants a full engine they install and own, with no credit meter on basic editing, is better served by GDevelop, an open-source engine with an AI helper, by Summer Engine for 3D on Steam, or by the engine-plus-AI route in our Godot coding guide. Inside the browser, Playabl is the closest like-for-like rival, Astrocade is the phone-first one, and Nilo builds 3D worlds with friends. For 3D props on their own, dedicated model generators such as Meshy and Tripo are compared in our 3D model generator guide. Developers who would rather write the code themselves can point Claude Code at a web game instead, and Rosebud's agent-publishing page lets such coding agents publish straight to a Rosebud link.
