ZeroScript - Free AI Agent for Roblox Studio

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

• Windows: double-click start.bat inside the extracted folder.
• macOS: double-click MacOS_Start.command inside the extracted folder. The first time, macOS will show a security warning ("could not verify... free of malware") - this is normal for any script downloaded outside the App Store, click Done, then go to System Settings > Privacy & Security, scroll to the bottom, and click Open Anyway. You only need to do this once.

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.

• 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 1.4.9

• Popup: new Settings button opens the Switch AI / support panel without needing an already-started conversation, and the footer no longer singles out chat.deepseek.com since seven providers are supported.
• Bridge: auto-recovers its own port on relaunch instead of crashing with a cryptic error when a previous Bridge was still holding it - and gives a clear, actionable message with the exact commands to fix it when the port is held by something else.
• Fixed the agent parsing/executing commands while its AI tab was backgrounded or the window minimized (observed live on GLM), which could run a tool blind or send duplicate feedback. It now pauses - with no time limit - until the AI tab is foreground again, then resumes exactly where it left off.

New in 1.4.8

• macOS support: a new double-clickable MacOS_Start.command launcher runs the Bridge on macOS, no Terminal knowledge required.
• DeepSeek: fixed a possible stuck send when a tool result was too long for DeepSeek's input box - it's now trimmed to fit automatically.

New in 1.4.7

• Qwen: fixed a rare "done but nothing happened" tool call: with repeated commands a tool chip could show a green check while the command never actually ran and returned no result. The agent now tracks each Qwen turn by a stable id, so it no longer confuses two similar turns.
• Image support that follows the model you pick: on Qwen, screenshots and image input are enabled only on its vision-capable models and turned off on text-only ones, updating when you switch models. On DeepSeek, choosing the Vision tab now enables screenshots and image input for it.
• DeepSeek: fixed image sending: a captured screenshot used to be attached twice and never sent. It now uploads once and sends correctly.
• Qwen: fixed the bar covering the "Expand more models" menu.
