Build Roblox games
with AI agents
Connect any model to the official Roblox Studio MCP. BloxBot is a free, open-source desktop app that lets AI agents operate Studio for you. Describe what you want, and watch it build.
Make a racing game with desert, neon city, and sky island tracks. Add vehicle physics and a multiplayer lobby.
Done. I've created three tracks with terrain, obstacles, and checkpoints:
All deployed to your Studio workspace. Ready to playtest.
Features
Everything you need to build games
Agentic Studio control
BloxBot doesn't suggest code. It operates Roblox Studio directly. Parts, scripts, terrain, UI, entire game systems.
Official Roblox Studio MCP
Powered by Roblox Studio's built-in MCP server. Your AI sees your full project structure, assets, and scripts in real time. No plugins to install.
Any AI model
Claude Fable 5, Gemini 3.5 Flash, GPT-5.5, or local models. BloxBot works with whatever fits your needs and budget.
Production-ready Luau
Generates typed Luau scripts with proper error handling and Roblox best practices. Not toy code.
Zero coding required
Describe what you want in plain English. Beginners and experienced developers alike.
Completely free
No subscriptions, no paywalls. Open-source under MIT. Inspect, fork, or contribute.
How it works
From zero to game in three steps
Download and enable
Download BloxBot and open Roblox Studio. Enable the built-in MCP server in Studio's Assistant settings. No plugins, no config files, no terminal.
Connect your AI
Pick your model. Claude Fable 5, Gemini 3.5 Flash, GPT-5.5. The AI connects to Studio's official MCP and gains full context of your project.
Describe and build
Tell the AI what to create in plain language. BloxBot translates your ideas into real Studio actions: scripts, parts, terrain, UI.
Add coin pickups with sparkle effects and a score counter
Created 20 coins with particle effects, a ScreenGui counter, and collection sounds. Coins respawn after 30 seconds.
Benchmarks
Which models are best for Roblox?
Results from Roblox's OpenGameEval benchmark — 117 evaluations across two skill categories. All of these models are available in BloxBot.
Pass@1 = first-attempt success rate. Pass@5 = success within 5 attempts. Source: Roblox/open-game-eval
