Works with

Roblox Studio (Windows, macOS, Linux)

A desktop app plus Studio plugin that reads your place, writes Luau scripts and UI, then starts a playtest, clicks through it and fixes what fails. It can also drive Blender to model and animate assets and import them into Studio, and its MCP server lets Claude Code, Cursor or Codex use the same Studio tools. Two ways to pay: Ropilot credits that include the AI, or a monthly Studio-actions plan where you bring your own Claude or ChatGPT subscription. Ropilot's terms give you a royalty-free licence to use and distribute what it generates rather than ownership, and it keeps prompts and outputs partly for product improvement.
