ZeroScript - Free AI Agent for Roblox Studio

GitHub stars Platform License

ZeroScript is a free browser extension that turns DeepSeek, Gemini, Kimi, GLM, Qwen, Arena or Meta AI into a Roblox Studio AI agent. Control Roblox Studio with AI directly from your browser - read/edit scripts, run Luau, generate assets, all from a normal AI chat. No API key, no terminal, no coding needed.

🌐 Website: zeroscript-five.vercel.app the free Lemonade.gg / Luamotion alternative for building Roblox games with AI.

Seven AI providers are supported: DeepSeek (chat.deepseek.com, recommended), Google Gemini (gemini.google.com), Kimi (kimi.com, Moonshot AI), GLM (chat.z.ai, Z.ai), Qwen (chat.qwen.ai), Arena (arena.ai, a multi-model playground) and Meta AI (meta.ai). Gemini and Kimi can be unstable: Gemini tends to stop using the Roblox tools in long sessions, and Kimi sometimes uses its own native tools instead of the Roblox commands. On Arena, use Direct mode (ZeroScript only supports Direct; it blocks Start in Battle / Side-by-Side / Agent modes). DeepSeek is the recommended provider.

⚠️ ZeroScript is Free Beware of Paid Copycats

ZeroScript is 100% free and open-source. It always has been, and it always will be. There is no official paid version, no subscription, and no sign-in required to use the extension.

If you come across a site or extension using the ZeroScript name that asks for payment or account creation, it is not this project. The only official links are the ones listed at the top of this README.

How it works

AI chat (DeepSeek / Gemini / Kimi / GLM / Qwen / Arena / Meta AI, in your browser) -> ZeroScript Extension -> Bridge (your PC) -> Roblox Studio

The extension runs inside the chat page (DeepSeek, Gemini, Kimi, GLM, Qwen, Arena or Meta AI). When you type a request, it sends commands to the Bridge running on your PC, which drives Roblox Studio through the built-in MCP server.

Setup

📺 Lost? Watch the setup tutorial on YouTube it covers every step below.

1. Download the zip and install the extension

Download the latest zip from the Releases page and extract it. The zip contains both the Bridge and the extension folder.

To load the extension:

  • Go to edge://extensions (Edge) or chrome://extensions (Chrome)
  • Enable Developer mode (top right toggle)
  • Click Load unpacked
  • Select the zeroscript-extension folder from the extracted zip

2. Start Roblox Studio and enable MCP

Open Studio and load a Place, then enable MCP (first time only):

  • Click Assistant AI in the top bar
  • Click ... (top right of the Assistant panel)
  • Click Manage MCP Servers
  • Click Enable Studio as MCP Server

Not sure where to find these options? The video tutorial shows exactly where to click.

3. Run the Bridge

Double-click start.bat inside the extracted folder. A small window opens, that means the Bridge is running.

4. Start a session

Go to https://chat.deepseek.com (recommended), https://gemini.google.com, https://www.kimi.com, https://chat.z.ai, https://chat.qwen.ai or https://arena.ai and open a new chat. The ZeroScript bar appears above the input box. Click Start session. Type what you want to build.

Only works on chat.deepseek.com, gemini.google.com, kimi.com, chat.z.ai, chat.qwen.ai and arena.ai - it will not work on any other site. On Arena, keep the mode dropdown on Direct - ZeroScript blocks Start in Battle / Side-by-Side / Agent modes (it only drives a single Direct reply). Gemini and Kimi can be unstable (model behavior, not the extension): Gemini may stop using the Roblox tools after a while, and Kimi may use its own native tools instead. If the AI starts answering in plain text instead of acting, remind it to use the commands or start a new session.

What the AI can do

  • Read and edit scripts
  • Run Luau code directly in Studio
  • Inspect the game tree and instances
  • Generate meshes, materials, and models
  • Browse and insert from the Creator Store
  • Control play-testing
  • Remember your project across sessions persistent project memory saved inside your place

New in 1.4.6

  • Fixed the ZeroScript bar covering Kimi's popups: Kimi's login card and the "Too many people are chatting" nag are modal popups, not standard dialogs, so the agent bar and its warning pill used to sit on top of them and could block their buttons. The bar now gets out of the way while either is open.
  • Kimi now defaults new chats to K2.6: Kimi's own K3 model is flagged unstable here, and most people never think to switch it. A brand new chat now starts on K2.6 automatically; picking K3 yourself on that chat is left alone.

New in 1.4.5

  • Fixed DeepSeek re-running old commands when you scroll up: in a long conversation, scrolling back into earlier messages could make an already-executed command run again. The agent now recognizes scrolled-back history and never re-fires it.
  • Fixed Gemini "Message could not be sent": after a reply, Gemini's send button could stay stuck on its stop icon, so a tool result never reached the model and the agent stalled. ZeroScript now un-sticks the button and sends normally, without that reset being mistaken for you stopping the agent.

New in 1.4.4

  • Fixed Qwen firing commands mid-stream: a Qwen frontend update made the stream report "finished" about 12 seconds before it actually closes, so a command could be sent while Qwen was still writing it, surfacing as a premature "Bad JSON" error. Generation detection now relies on the real stop button instead.
  • Removed the "unstable" badge on Qwen's Auto/Think modes: those modes used to make Qwen claim a tool didn't exist without trying it.
  • Safer destructive actions: the AI is now required to confirm the exact target before any Destroy, ClearAllChildren, or similar command, instead of clearing a whole container "to be safe."
