The Sandbox says more than 12,000 people have applied for access to The Sandbox Studio, although only 30 experienced creators have as yet been admitted to its deliberately restricted alpha program.
Announced in June, The Sandbox Studio is the company’s new AI-powered game development environment, intended to provide creators with more accessible tools for building standalone games and experiences. Its first month has focused on improving the product alongside a small group of developers before access expands toward a public beta.
The selected alpha creators include developers with experience using Roblox, Unity and Unreal Engine, alongside builders already working with AI coding tools such as Cursor, OpenAI Codex and Claude Code.
The Sandbox said limiting access has allowed its team to offer direct support, run small workshops and respond to feedback within days rather than waiting for a longer product development cycle. It now plans to add up to 10 creators each week while preparing a larger beta Game Jam.
The first closed alpha Game Jam started last week. Beyond encouraging creators to make games, the event is designed as a production test for the Studio editor, SDK, asset pipeline and engine APIs.
Early feedback has already informed a series of technical updates. For example, the Studio’s starter templates have meanwhile received updated lighting and post-processing. The revised templates cover first-person shooters, third-person games, side-scrollers, vehicles, virtual reality and free-camera experiences.
Access is also becoming less dependent on GitHub. The new Creator Portal allows approved users to log in with their existing The Sandbox account and download the editor directly. Alpha whitelisting is still required, but The Sandbox says that restriction will be removed when the platform enters beta.
The portal will eventually become the main location for Studio downloads, release notes, technical changelogs and a planned creator marketplace.
Development priorities for the coming months include multiplayer foundations, leaderboard services, new asset and skill collections, expanded genre templates and in-editor support for The Sandbox’s Agent Nova AI assistant. Other work includes voxel-world production tools, compatibility with the C.A.R.S. character rigging system and the integration of The Sandbox account login into games themselves.
The Sandbox is also holding weekly Thursday livestreams on Twitch, where its developers demonstrate Studio features, answer questions and build projects alongside the creator community.
The company has not yet announced a firm date for the public beta, but the combination of weekly alpha admissions and a broader beta Game Jam suggests access will expand incrementally rather than through a single unrestricted launch.
