Build Roblox games and Blender assets with AI that knows both.

A desktop app for Roblox Studio and Blender development. You pick the model, review every proposed change before it lands, and can hand long jobs to Roblox Cloud and Blender Cloud.

Version 0.1 is an early release. Installers are not code-signed yet, so Windows SmartScreen and macOS Gatekeeper will warn (on macOS: right-click the app, then Open). Each release lists SHA-256 checksums.

Four models, one job each

Orbit, Nebula, Solar and Nova are Space Studio configurations built on Anthropic Claude: each has its own instructions, tools and budgets. They are not fine-tuned, and their version numbers are Space Studio's own, not Anthropic's.
