Roblox AI Studio Agent

Roblox AI Studio Agent is an AI agent in the terminal that builds Roblox places in Studio including parts, models, UI, and Luau scripts.

Stud is an open source AI agent running in the terminal to build Roblox places straight into Studio. It creates parts, models, UI, and Luau scripts using either a free local model via Ollama or user-provided keys for Claude, GPT, or Gemini. The tool shows a diff of every change before applying it and executes playtests to check for errors, fixing issues and taking screenshots. It integrates via Studio's built-in Model Context Protocol server and a companion plugin to record changes as single undo steps. Developers use it with Rojo projects or git repositories to follow custom code styles defined in project markdown files. It operates locally with no telemetry, credits, or paid tiers.
