The Free Alternative to Lemonade.gg and Luamotion for Roblox Studio

Build Roblox games with AI no subscription, no account, no cost.

If you’ve been using Lemonade.gg or Luamotion to speed up your Roblox development, you already know the value of having an AI agent inside Roblox Studio. The problem? Both tools come with a price tag and for indie developers or beginners, that cost adds up fast.

ZeroScript Free is the open-source alternative that gives you the same core capabilities, completely free.

What is ZeroScript Free?

ZeroScript is a Chrome/Edge browser extension that turns DeepSeek (or Gemini) into a fully functional Roblox Studio AI agent. No subscription. No account required. No terminal.

It works by injecting into the DeepSeek or Gemini chat interface and connecting it to a lightweight Python bridge running on your PC. That bridge talks directly to Roblox Studio through its built-in MCP server.

DeepSeek / Gemini (browser) → ZeroScript Extension → Bridge (your PC) → Roblox Studio

What the AI can actually do

Once set up, you can ask the AI to:

• Read and edit scripts directly in Studio
• Run Luau code in real time
• Inspect your game tree and instances
• Generate meshes, materials, and models
• Browse and insert assets from the Creator Store
• Control play-testing

All of this happens from a chat interface type what you want, watch it happen in Studio.

DeepSeek is free to use at chat.deepseek.com with no API key needed you just use the web interface. ZeroScript injects into that page and adds the Roblox Studio controls on top.

Gemini (gemini.google.com) is also supported, but it can become unstable during long sessions and may stop using the Studio tools after a while. DeepSeek is the recommended provider for consistent results.

It’s fully open-source

This is the part that matters most if you’re skeptical.

Every line of code is public on GitHub: github.com/sebattfg/ZeroScript-Free

You can audit exactly what the extension does, what the bridge sends to Studio, and how the MCP connection works.

Getting started

Requirements: Windows PC, Roblox Studio, Chrome or Edge, Python 3.8+

1. Download the latest zip from the Releases page
2. Load the extension in Chrome/Edge (developer mode, load unpacked)
3. Enable MCP in Roblox Studio (Assistant → Manage MCP Servers → Enable Studio as MCP Server)
4. Run start.bat to launch the bridge
