Make a little
awesome.
KidsCode is a free playground for curious minds. Guide a robot, snap code blocks together, make pixel art, and write real Python, right in your browser. Big ideas, tiny steps.

Meet your programming
building blocks.
Variables, if/else, loops, lists, and more. Learn by snapping real programs together in 20 playful missions.
Fun coding activities
for kids, from the first click.
Start with a robot. Make your own art. Type your first line of Python. There’s more than one way to become a maker.
Give Bit a mission
Tell a little robot where to go. Collect stars and discover the magic of instructions and loops.
Think in pixels
A tiny square can be the start of something big. Build colorful pixel art, one coordinate at a time.
Meet real Python
Make your code talk, think, and repeat. Learn by changing real programs and seeing what happens.
A little code.
A big hello.
Computers need instructions. This one says: “show my message.” Choose a message and see what happens when you run it.
Pick an idea
Every great thing starts with a little “what if?”
Try. Tinker. Try again.
Mistakes are clues. Follow them somewhere fun.

Don’t just play.
Make the thing.
A silly story machine
An otter. The Moon. Too many pancakes. Your code gets to tell the story.
PUT YOUR THINKING HAT ONBecome a bug detective
Spot the tiny mistakes. Predict what happens. Collect a few “aha!” moments.
YOUR NEW LITTLE SIDEKICKBuild a pocket robot
Give it a name, some energy, and a personality. Then teach it a new trick.
You bring the imagination.
We’ll bring the starting line.
Free coding for kids,
one small step at a time.
KidsCode is a free website where children learn programming by playing, building, and experimenting. Everything runs in a web browser. There is nothing to install and no account to create.
Who it’s for
Kids from about age 7 who wonder how computers follow instructions. Robot missions and pixel art need no typing. The Python trail suits confident readers and typists, often ages 10 and up. Grown-ups are welcome to tag along.
What kids learn
Sequences, loops, variables, if/else decisions, comparisons, lists, dictionaries, functions, and debugging. Many ideas show up twice: first as blocks you snap together, then as real Python you type.
How it works
Pick an activity and press Run. Progress, drafts, and pixel art are saved in the browser on your device. KidsCode works on computers, Chromebooks, and tablets; the block editor likes a bigger screen.
Pick a trail.
Start anywhere.
Two step-by-step coding courses for kids, plus games and creative tools. Each lesson takes about 5–12 minutes.

Is KidsCode free?
Yes. Every activity, lesson, and playground on KidsCode is free to use. There are no paid levels, subscriptions, or locked lessons.
Do I need to know anything about coding?
Nope! Start with Code Adventures. You can tap commands to guide Bit, with no typing needed. When you’re ready, the Python trail starts at the very beginning.
What ages is KidsCode for?
The visual activities are designed with roughly ages 7–10 in mind. The Python trail suits confident readers and typists, often ages 10 and up. These are starting points, not rules: pick what feels interesting and ask a grown-up for a hand.
Do kids need an account?
No. There is no sign-up or login. Completed activities and your playground draft can be saved in this browser on this device. Clearing browser data removes that progress, and it does not sync to other devices.
Can I really run Python here?
Yes. The Python playground runs real Python in your browser. Nothing to install. The first run downloads the Python engine, so it needs an internet connection and may take a moment.
Is KidsCode like Scratch?
It’s a similar idea: you snap blocks together instead of typing. KidsCode’s block lessons are built with Blockly and focus on programming foundations such as variables, decisions, loops, and lists. You can turn your blocks into Python when you’re ready. KidsCode is independent and is not part of Scratch.
Which devices work best?
A computer, Chromebook, or tablet with an up-to-date web browser. Robot missions, pixel art, and the Python lessons also work on phones. The block editor has more room on a bigger screen.
