Build a Roblox game with AI, from a single sentence
Builblox is an AI that builds Roblox games. You write what you want — "a haunted theme-park tycoon", "an obby where the floor melts behind you" — and it plans the systems, writes the Luau scripts, places the parts and draws the GUI, straight into the place open in your Roblox Studio.
How the AI builds your game
It starts with a conversation. You describe your idea in the chat and Builblox answers with a plan: the title, the art direction and the build steps, from one to nine depending on how ambitious the game is. You read it, adjust if needed, then start the build.
At each step the AI writes precise operations — create a folder, place a part, write a script — and the Builblox plugin applies them inside your place. It then reports the real state of Studio back, so the next step builds on what actually exists rather than on what the model imagines.
Once the last step is in place, a verification pass reads the whole thing without spending a credit. If it finds a definite defect, a single fix is run. You get a game that opens, plays and publishes.
What you get inside Roblox Studio
Nothing is hidden in a proprietary format: everything arrives as ordinary Studio objects, filed under a Builblox folder in your Workspace. Scripts are readable, parts can be moved, the GUI can be edited. One Ctrl+Z undoes a whole step.
- Server and client Luau scripts: game loop, shop, DataStore saves, leaderboards.
- The map: terrain, spawn, lighting, parts and models placed where they belong.
- The GUI: HUD, menus, buttons, wired to the systems they control.
- The remotes and services that hold everything together.
Who it is for
For anyone with a game idea and no six months to spare. A beginner gets a complete game without writing a line of Luau. An experienced developer saves the setup hours — core systems, shop, saves — and keeps their time for what makes their game unique.
Builblox speaks French and English and runs in the browser. You need Roblox Studio on a computer and the Builblox plugin, available on the Creator Store.
Around the game: thumbnails, stats, 3D models
A Roblox game is not just its code. Builblox also generates the thumbnail that earns its clicks, tracks what works on the platform all day with TrackBlox, scores your idea before you build it, and sculpts textured 3D models to import into Studio.
Frequently asked questions
Do I need to code to build a Roblox game with Builblox?
No. You describe, Builblox writes the Luau. Being able to read a script helps when customising, but it is not needed to get a working game.
Do I own the game?
Yes. The games, scripts, maps and thumbnails produced with Builblox are yours. You publish and monetise them without paying us anything.
How is this different from Roblox Build, Roblox's own tool?
Roblox Build is the official tool launched in 2026, mobile-first and region by region. Builblox works inside Roblox Studio on desktop, from an empty or existing place, and leaves every object and script in the open for you to edit.
