AppLab, our coding tool for middle and high school, is now open for anyone to build JavaScript apps. If you’re ready to go beyond block-based coding, the new Hour of Code tutorial helps you design a “choose your adventure” app in JavaScript or blocks. Making your own web app has never been easier.

10 million girls have accounts on!
This milestone is personal for me. If only 1% of the girls actively learning on continued past high school, they’d outnumber the gender gap in university CS!

I’m immensely proud of all the students — boys and girls — who have shown that anybody can learn. We can’t wait to see what you create.

What matters most comes after the Hour of Code
From Afghanistan to Zimbabwe, every country is participating in the Hour of Code, and together we’ll pass 500 million “hours served” to celebrate the 4th anniversary of this incredible campaign.

But one hour is only the beginning. Go beyond an Hour of Code and pledge to bring computer science to your school.

The global movement continues to accelerate, thanks to you and your support for our shared vision that every student in every school deserves the opportunity to learn computer science.

I’m forever humbled and grateful for your support.
