A Roblox game generator that actually builds the game
An idea generator gives you a paragraph. A script generator gives you a file to paste. Builblox does both and goes all the way: it builds the whole game inside your place — systems, map, GUI — and leaves it open in Studio, ready to test.
The genres it can generate
Builblox is tuned on what works on Roblox. The most requested genres come out with the systems players expect: a tycoon has its droppers, purchases and saves; a simulator has its collection loop, rebirths and leaderboard; an obby has its checkpoints and traps. You can mix them, and you can ask for anything else.
- Obby and parkour, with checkpoints, traps and a timer.
- Tycoon, with droppers, upgrades, DataStore and shop.
- Simulator and clicker, with rebirths, pets or multipliers.
- Horror and survival, with rounds, roles and dynamic lighting.
- Roleplay, café, school: interactions, jobs and currency.
- Arena and PvP: queues, rounds, scores.
A plan before generation
The generator does not rush in. It first proposes a plan in steps, system by system, and waits for your go. That is where you refine: "the leaderboard must be weekly", "the shop sells skins, not advantages". Each step is then built, checked in Studio, and becomes the base of the next.
Continue a game you already started
Already have a place? Open it, connect the plugin, and ask for what you want added. Builblox reads what exists — services, folders, scripts — before writing anything, so the new systems fit around yours instead of overwriting them.
The AI models behind the generator
Builblox AI, tuned for Roblox, is included in every plan. Pro and Studio add frontier models such as Claude Opus 5.5, selectable from the menu next to the prompt, and the option to plug in your own API key.
