Blox Builder is the AI co-pilot built for Roblox Studio. Describe a tycoon, an obby, a simulator — and watch Luau scripts, parts, UI, terrain and full systems stream into your project in real time.
Blox Builder lives inside Roblox Studio as a dockable plugin. Chat, generate, preview and apply — all without leaving your project.
DailyRewards.server.lua + RemoteEvent + DataStore2 wrapper. Streaming…From the first line of Luau to a fully-playable tycoon — Blox Builder handles the boring parts so you can focus on the fun parts.
Type a behaviour in plain English, get idiomatic, type-safe Luau — with comments, return types, and Roblox-API aware patterns baked in.
Parts, models, folders, terrain, lighting, skyboxes. Blox Builder scaffolds entire maps from a single sentence and respects your project structure.
Generate ScreenGuis, frames, buttons, and animations. Bind them to RemoteEvents with one prompt — no more hand-wiring 20 instances.
Watch Luau stream line by line, exactly like Cursor. Stop, redirect, and continue — the model picks up from where you cut it off.
Hook into the output console. Blox Builder explains stack traces inline, proposes a fix, and patches the script — all from a single slash command.
Split a 1,200-line script into clean ModuleScripts, add type annotations, or just ask "what does this do?" — Blox Builder reads the whole tree.
No boilerplate, no scaffolding, no "find/replace this token". Blox Builder produces the script, the RemoteEvent, the DataStore wrapper, and the client UI in a single, atomic diff you preview before applying.
Set up the plugin and Studio Bridge on your PC, connect with your token, then describe what you want to build — the AI applies changes live in Roblox Studio.
Download the `.lua` plugin and add it to Roblox Studio so chat and Generate live inside your place.
Download plugin →Unzip and run Start-BloxBuilder-Bridge.bat. Leave that window open so Studio stays connected to our API while you build.
Sign in → Dashboard → Copy token → paste it in the plugin. Optionally click Connect Studio Bridge on the dashboard.
Open dashboard →In Roblox Studio: Assistant → Manage MCP Servers → enable Studio as MCP server so the agent can edit your place live.
Type a prompt in the plugin and hit Generate. The agent explores Studio, builds systems, and applies changes while Bridge stays connected.
Full setup guide →Generic AI code tools get Roblox wrong in subtle, expensive ways. Blox Builder is trained on the Roblox API, idiomatic Luau, and a year of community patterns.
Our obby went from blank baseplate to fully playable in one afternoon. The DataStore patterns it generated were better than what I would have written — and I ship Roblox games for a living.
I used to bounce between VS Code, Studio, the docs, and three AI tools. Blox Builder replaced all of them. The fact that it lives inside Studio is the unlock — I never lose context.
The diff preview is the killer feature. My team can review AI changes like a PR before they ever touch the game tree. It feels safe, not magical.
