What is Roblox?
Reimagining the way people come together: explore, create, and share endless unique games.
Roblox is an immersive gaming and creation platform where millions of people explore, create, and share games. Its "Build" feature turns text prompts into playable games directly inside the Roblox mobile app: describe what you want, and Build generates a starting point covering gameplay mechanics, environment, characters, visual style, and sound, which you can iterate on, playtest, and publish. Build is powered by open-source and proprietary Roblox models including the Cube 3D foundation model, shares a back end with Roblox Studio so projects can move from phone to desktop, and is joined by agentic helpers for playtesting, analytics, and experimentation. A free base tier is available, with paid options for power users.
