Teach kids to code,
one mission at a time.
CodeNest Kids turns block-based coding into real Python — through 12 missions, two game types, and a whole lot of snake mascot energy. Free, offline, and built for ages 7-10.
Blocks today, real python tomorrow
Every block a kid drags generates genuine, readable Python underneath - visible any time with one tap.
Blocks → Python bridge
Drag-and-drop blocks generate real Python code, shown live in a "Show Python code" drawer - the actual bridge from visual coding to text-based programming.
Two full game types
Guide a robot through themed mazes, or play an arcade catch-game dodging bombs and grabbing stars - two different ways of thinking about code.
100% offline
Every font, sound effect, and library is bundled or synthesized locally. No internet connection needed after install - safe, private, and always available.
From a sunny meadow to a candy castle to outer space - every mission has its own cartoon backdrop and story.
