Coding education goes
where the kids already are.

A world where education
finds the children

Children are already inside Roblox — spending more than 2 hours a day in the game world. Code Builder brings coding education to them. Not "come study," but "learn while you play."

The block coding window doesn't pause the game. It deepens immersion. Writing code is enjoyable; failing makes you want to try again. That's Code Builder.
