Rosebud AI

Rosebud AI is a browser-based AI game maker that turns plain-language descriptions into playable 2D, 3D, and voxel games, generating code, art, and sound together in a single flow. The company was founded in 2019 in San Francisco by Lisha Li, who holds a PhD in machine learning from UC Berkeley and previously worked as a principal at Amplify Partners, and went through Y Combinator's Summer 2019 batch backed by investors including Jeff Dean and Adam D'Angelo. Rosebud started as a synthetic media platform generating AI faces for marketing and fashion use cases before pivoting toward interactive game creation, eventually landing on its current "vibe coding" approach to game development, where users describe an idea and iterate by chatting rather than writing code from scratch.

The platform is built on Three.js, letting games run as real WebGL experiences directly in the browser with no downloads, plugins, or installs required, either to build or to play. Users start by describing a game genre, mechanic, or feeling in a single prompt, or choosing from templates spanning visual novels, horror, RPGs, racing, puzzle, and idle/clicker genres, and Rosebud generates a working, playable version they can immediately test and refine through natural language chat ("make the jumps floatier"). Beyond core game logic, the platform generates AI-powered NPCs with memory and responsive dialogue, in-game AI mechanics like adaptive difficulty and procedural quests, and companion tools including PixelVibe for sprite and tileset generation and AI Skyboxes for environment art, all without leaving the same workflow. On paid plans, users can open and directly edit the underlying JavaScript code, giving more technical creators a way to go beyond what pure prompting can produce.

Rosebud reports over 2.5 million games made on the platform, with success stories including solo-developed titles that reached Steam and Epic Games, and a solo-built MMORPG called Legion Hunters. The platform serves hobbyists, students, educators, and indie developers wanting fast, shareable prototypes rather than AAA-scale production, with a dedicated education program used by teachers to teach real game development concepts. Every published game gets a one-click shareable browser link that anyone can play instantly, with an optional remix mode letting other creators build on top of existing published games. Commercial usage rights, letting creators sell what they build with no commission taken by Rosebud, are included starting at the 10x Dev and Pro paid tiers.

Rosebud AI offers a free tier that includes a limited weekly allowance of prompts (reported around 20 prompts per week for continued access to existing projects) for creating and playing games, with no commercial usage rights and no code access. Paid plans sit above the free tier, including a Pro plan (third-party trackers report pricing around $19/month) and a higher "10x Dev" tier, both of which unlock significantly more AI generations, larger and more complex projects, direct access to edit the underlying generated code, and full commercial usage rights, letting creators sell games and assets with 100% of profits retained and no commission taken by Rosebud. Compute-heavy tasks like 3D rendering and complex animations can consume additional "Spark Credits" on top of a subscription for heavier projects. An Enterprise tier exists for organizations needing team management and collaboration features not available on individual plans. Because Rosebud adjusts pricing and credit allowances as its underlying model costs change, the live pricing page under "My Plan" on rosebud.ai is the most reliable source for exact current figures.
