roblox studio
You

Make a racing game with desert, neon city, and sky island tracks. Add vehicle physics and a multiplayer lobby.

AI

Done. I've created three tracks with terrain, obstacles, and checkpoints:

+ Track_Desert: sandy terrain, cactus gates
+ Track_NeonCity: neon ramps, boost pads
+ Track_SkyIsland: floating platforms, cloud jumps
+ VehiclePhysics, Lobby, Matchmaking scripts

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

Opus 4.6, Big Pickle from OpenCode, Gemini 3 Pro, 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
