Rosebud AI

Rosebud AI is an AI-powered game creation platform that lets anyone build and deploy playable 3D games and interactive worlds from natural-language prompts, a workflow the company calls "Vibe Coding" — you describe scenes, rules, and behaviors and an AI assistant named "Rosie" writes and applies the underlying JavaScript. The platform runs on a custom engine designed for AI-era game development, featuring deterministic WASM-based physics, native real-time multiplayer, instant link-based sharing, and a built-in "Juice API" for camera effects, particle systems, and spatial audio. Founded in 2019 in San Francisco by CEO Lisha Li (Ph.D. in machine learning, UC Berkeley), Rosebud AI is backed by a16z. As of this enrichment pass the company ships a hosted consumer product and publishes no public developer API, OpenAPI/AsyncAPI specification, SDK packages, MCP server, or developer portal.

Rosebud AI is profiled on the APIs.io network. Tagged areas include Company, Artificial Intelligence, Game Development, Game Creation, and No-Code.
