⚠️ ZeroScript is Free & Open-Source Beware of Fake Paid Copycat Sites

sebattfg — Sun, 19 Jul 2026 21:59:27 +0000

Official Notice

ZeroScript is a free, open-source project. It always has been, and the core extension always will be.

There is currently a website impersonating ZeroScript's name and logo, offering a paid sign-in system. This is not affiliated with the official ZeroScript project in any way.

How to identify the official ZeroScript

Official GitHub repo: github.com/sebattfg/ZeroScript-Free
Official site: zeroscript-five.vercel.app
First commit: June 9, 2026
License: Open-source, free to use
Official articles: published on dev.to and Medium under the author sebattfg
No sign-in, no paywall, no account required to use the core extension

Red flags of the fake site

Requires account creation / sign-in
Offers paid access to what is a free tool
Copies the ZeroScript name and logo
Hosted on a generic site builder with no real technical content, no changelogs, no GitHub link, no verifiable authorship

Why this matters

ZeroScript was built as a free alternative to paid Roblox Studio AI tools like Lemonade.gg. A paid copycat using the same name defeats the entire purpose of the project and misleads users who are specifically looking for a free option.

Summary for reference

Official project: github.com/sebattfg/ZeroScript-Free
Status: free, open-source, no sign-in required
Any ZeroScript-branded site requiring payment or account creation, not linked to this repository, is a copycat and not the official project.

What to do if you encounter the fake site

Do not enter any payment information
Do not create an account
Use the official free version from GitHub instead
Report the site if possible

ZeroScript 1.4.0: Free AI Agent for Roblox Studio Now Connects to Other MCP Servers (Blender, Sketchfab...)

sebattfg — Thu, 09 Jul 2026 10:41:53 +0000

If you build games in Roblox Studio and wish you could just talk to an AI and have it write Luau, edit scripts, and build your game world for you, you might not know that a free option already exists.

ZeroScript is a free, open-source browser extension that turns DeepSeek, Gemini, Kimi, GLM, Qwen, or Arena into a full AI agent for Roblox Studio. No API key. No terminal. No coding required to set up. You open a normal AI chat in your browser, and it can read/edit your scripts, run Luau code, generate assets, and control play-testing, directly in Studio.

It's positioned as a free alternative to paid tools like Lemonade.gg or Luamotion, since it works with AI providers that are free to use.

How it works

AI chat (in your browser) -> ZeroScript Extension -> Bridge (your PC) -> Roblox Studio

The extension lives inside the chat page itself. When you type a request, it relays commands to a small local Bridge app running on your PC, which talks to Roblox Studio through Studio's built-in MCP server.

What's new in 1.4.0

The headline feature this update: ZeroScript can now connect to other MCP servers alongside Roblox Studio. This is still experimental, but it's a meaningful shift, since ZeroScript stops being just a Roblox tool and starts being a general-purpose orchestrator.

Concretely, from the panel's menu, you can now add an addon MCP server (Blender, Sketchfab, or any local MCP command). Roblox Studio stays the always-on primary connection, and the AI only reaches for an addon when the task actually needs it. If Roblox Studio goes down but an addon server is still alive, the agent can start in a degraded mode instead of refusing to run entirely.

Practically, this opens the door to workflows like modeling in Blender and importing straight into your Roblox place, all from the same AI chat session.

Other improvements in this release:

Better vision support across providers. Arena, Gemini, GLM, Kimi, and Qwen can now reliably see screen captures or images returned by tools, with a fixed upload flow that no longer silently drops attachments.
Smarter command recovery. If a command gets cut off by the model's own output limit (only missing its closing brackets), ZeroScript now auto-completes and runs it instead of forcing a full retry. Error feedback is also more specific: cut off, bad JSON, missing marker, or wrong format, so the AI can self-correct faster.
More accurate tool status chips, including a fix for a DeepSeek-specific bug where a command's chip showed as finished while the AI was still writing it. ## Supported AI providers

ZeroScript currently works with six free AI chat interfaces:

DeepSeek (chat.deepseek.com) - the most stable, recommended as your default
Google Gemini (gemini.google.com)
Kimi (kimi.com, Moonshot AI)
GLM (chat.z.ai, Z.ai)
Qwen (chat.qwen.ai, Alibaba Cloud)
Arena (arena.ai) - a multi-model playground, use Direct mode only Gemini and Kimi can occasionally be less consistent about sticking to Roblox tool calls in long sessions, that's model behavior rather than an extension bug, and usually a quick nudge or a fresh session fixes it.

What the AI can actually do in Studio

Read and edit scripts
Run Luau code directly
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, thanks to persistent project memory saved inside your place

Getting started

Grab the latest zip from the Releases page and load the extension as unpacked in Edge or Chrome (Developer mode).
Open Roblox Studio, load a place, enable the MCP server once from the Assistant AI panel.
Run start.bat to launch the local Bridge.
Open DeepSeek (or any supported provider) in your browser, click Start session, and start building. There's a full video walkthrough on YouTube if you'd rather watch than read.

The Best Free and Unlimited AI for Roblox Studio (No Subscription, No API Key)

sebattfg — Mon, 29 Jun 2026 11:05:28 +0000

If you're looking for free AI tools to help you script in Roblox Studio, you've probably noticed most "AI for Roblox" tools push you toward a paid subscription or require you to bring your own API key. There's a simpler path: use the AI chat interfaces you already have access to, connected directly to Roblox Studio.

That's what ZeroScript does. It's a free, open-source browser extension that connects multiple AI chat interfaces to Roblox Studio via MCP, no subscription and no API key needed. Here's a breakdown of which free AI providers work well for Roblox scripting, and how to use each one.

DeepSeek

DeepSeek is a solid default for Lua/Luau scripting. It handles standard Roblox patterns (RemoteEvents, DataStores, module scripts) reliably and is fast enough for quick iteration. Good first choice if you're not sure where to start.

Gemini

Gemini is the fastest of the bunch, good for quick iterations. The tradeoff is it's less precise than the others and can be a bit unstable, so double check the output before trusting it on anything critical.

GLM

GLM is a capable general coding model that performs well on Roblox-specific syntax. Worth trying as an alternative if you want to compare outputs against DeepSeek on the same prompt. Note that it's currently in high demand, so it can be unavailable at times.

Kimi

Kimi is very smart, but slower, and it has a tendency to get stuck in tool call loops.

Qwen

Qwen is another reliable option for everyday scripting tasks. Like GLM, it's worth keeping in rotation to compare results, since different models can produce noticeably different approaches to the same Roblox problem.

Arena

Arena lets you compare multiple models on the same prompt side by side, useful when you want to see which model handles a specific Roblox pattern best before committing to one.

How to connect any of these to Roblox Studio

All six providers above connect to Roblox Studio the same way with ZeroScript, a free browser extension. Here's the full setup:

📺 Prefer video? Full walkthrough: setup tutorial on YouTube

1. Download and install the extension

Grab the latest zip from the GitHub Releases page and extract it. It contains 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. Enable MCP in Roblox Studio

Open Studio, load a Place, then (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

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 chat.deepseek.com, gemini.google.com, kimi.com, chat.z.ai, chat.qwen.ai, or arena.ai and open a new chat. The ZeroScript bar appears above the input box. Click Start session, then type what you want to build.

On Arena, keep the mode dropdown on Direct, ZeroScript blocks Start in Battle / Side-by-Side / Agent modes.

Free Lemonade.gg Alternative for Roblox Studio: ZeroScript

sebattfg — Sun, 14 Jun 2026 11:28:47 +0000

If you've hit Lemonade.gg's 4-prompt free tier and don't want to pay $20/month, here's what I built instead.

ZeroScript is a free, open-source browser extension that connects DeepSeek, Gemini, GLM, Kimi, Qwen or Arena directly to Roblox Studio via MCP. No subscription, no credit limits, no paywall. Ever.

Why look for a Lemonade.gg alternative?

Lemonade.gg is a solid tool but the pricing is brutal for hobbyists:

4 free prompts total
$20/month for 100 prompts
No access to your own AI models

If you're building a game on the side, you hit the wall fast.

What ZeroScript does differently

ZeroScript uses Roblox Studio's built-in MCP server to give the AI direct access to your project. It runs on six free models, including DeepSeek, GLM 5.2, Kimi K2.6, Gemini Flash, Qwen and Arena, so there's no credit system to worry about.

	ZeroScript	Lemonade.gg
Price	Free forever	$20/month
Free prompts	Unlimited	Only 4
Runs Luau live	✓	✕
Generates meshes	✓	✕
Open source	✓	✕

What the AI can do in Studio

Read and edit your Luau scripts in place
Run code live to test and debug
Inspect your full game tree
Generate procedural meshes and materials
Browse and insert from the Creator Store

Setup in 4 steps

Download the zip from GitHub and load the extension in Chrome or Edge
Open Roblox Studio, click Assistant AI, enable MCP Server
Double-click start.bat, keep the window open
Open your preferred model's chat (DeepSeek, Gemini, GLM, Kimi, Qwen, or Arena) and click Start Session on the ZeroScript panel

That's it.

How to Use DeepSeek (and Other Free AI) in Roblox Studio for Free

sebattfg — Sat, 13 Jun 2026 09:47:39 +0000

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

GitHub: github.com/sebattfg/ZeroScript-Free

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
