The Story Behind It
CodeKids started as a personal weekend project. A parent wanted his children to discover the joy of coding and critical thinking — without ads, distractions, or sign-ups. Every puzzle and lesson has been playtested by real kids.
No signup, no downloads, no cost — just pick a path and play.
