If you've been using Lemonade.gg, you already know the pain: 4 free prompts, then $20 for 100 more. For a Roblox developer who codes every day, that adds up fast.
There's a better way. With ZeroScript Free, you can connect DeepSeek and other free AI models directly into Roblox Studio with no subscription, no prompt limits, and no paywall.
ZeroScript Free is an open-source Chrome/Edge extension that bridges your browser's AI chat interface directly to Roblox Studio via MCP (Model Context Protocol).
Instead of copy-pasting code between a chat window and Studio, ZeroScript lets the AI read your scripts, write changes, and interact with your project: all in real time.
- Free and open source
- Works with DeepSeek (free), and compatible with other AI models
- No API key required: uses the free web interface
- Unlimited prompts
Why DeepSeek?
DeepSeek is one of the strongest free AI models available right now. The web version at chat.deepseek.com is completely free with no rate limits that would block normal development use.
ZeroScript works by injecting into the DeepSeek chat interface and routing messages through a local WebSocket bridge into Roblox Studio. You type in DeepSeek, your game changes in Studio.
Other free AI models are on the roadmap. Gemini and ChatGPT are already partially supported (unstable for now) and the architecture is model-agnostic by design.
How it Works
The setup has three parts:
- The Chrome/Edge extension: injects into DeepSeek's chat interface and intercepts messages
- The Bridge (start.bat): a local server running on your machine that handles the WebSocket connection
- Roblox Studio MCP: the built-in MCP server in Roblox Studio that receives commands from the bridge
When you send a message in DeepSeek, it flows through the bridge into Studio. The AI can read your scripts, create objects, and make changes without you ever leaving the chat.
Setup Guide
Step 1: Install the extension
Download the extension from the GitHub repo. In Chrome or Edge, go to chrome://extensions, enable Developer Mode, and click "Load unpacked". Select the extension folder.
Step 2: Enable MCP in Roblox Studio
Open Roblox Studio, click the Assistant AI button, open its settings, and enable "Enable MCP Server". Studio will start listening for connections on a local port.
Step 3: Run the Bridge
Double-click start.bat from the downloaded files. A terminal window will open: keep it running.
Step 4: Start a session
Go to chat.deepseek.com. You'll see the ZeroScript panel. Click "Start Session" and you're connected.
That's it. Type in DeepSeek, watch Studio respond.
ZeroScript vs Lemonade.gg
| ZeroScript Free | Lemonade.gg | |
|---|---|---|
| Price | Free, unlimited | $20 / 100 prompts |
| Open source | Yes | No |
| AI model | DeepSeek (free web) | Proprietary |
| Setup time | ~2-3 minutes | ~8+ minutes |
| Prompt limit | None | 4 free, then paid |
What Can You Do With It?
Once connected, you can ask the AI to:
- Generate full Luau scripts and insert them directly into your project
- Debug errors from the output log
- Create and modify instances in the Explorer
- Refactor existing scripts
- Build systems (combat, inventory, UI, datastores) from a description
The AI has full context of your open Studio session: it reads your script tree before touching anything.
Roadmap
ZeroScript Free is actively developed. Planned features include:
- Gemini and ChatGPT support (use any free AI)
- Improved session stability
- Better context injection for large projects
