Best AI for Roblox development (Luau scripting)

The pick

Cursor

For most Roblox devs, the best setup is Cursor plus Rojo. Rojo syncs your Roblox Studio place to real files on disk, so Cursor's agent can read your whole project and write or refactor Luau scripts across many files. With the Luau Language Server extension, you get autocomplete and type checks too. It's a familiar VS Code-style editor, so it's easy for beginners, and you review every diff before it lands in your game. Roblox Studio's built-in Assistant is free and fine for small, single-script help. When your game outgrows that, switch to Cursor.

Setup guide

1. Install Rojo (and its Roblox Studio plugin), then run 'rojo init' to create a project.
2. Open the project folder in Cursor and install the Luau Language Server extension.
3. Run 'rojo serve' and connect from the Rojo plugin in Studio so files sync live.
4. Ask Cursor's agent for one system at a time (e.g. 'add a coin pickup with a leaderstat') and review the diff.
5. Playtest in Studio after each change; commit to Git so you can roll back.
