The Congressional App Challenge

The Congressional App Challenge
The Congressional App Challenge
The Congressional App Challenge (CAC) is a nationwide coding competition for middle and high school students in the United States.

Winners from each congressional district are invited to Capitol Hill in Washington, D.C., for the annual #HouseOfCode event, where they showcase their apps to lawmakers and the tech community.

The competition is open to students of all skill levels and encourages creativity and innovation from participants.

Join us as you work on your Congressional App Challenge project.

Here are a few projects you could get involved in:

Get free stuff

Dozens of teen-led hardware and software initiatives ('You Ship, We Ship') are run each year, from Tamagotchi clones and portable game consoles to 3D websites. The best part? It's all free, and completely open source.

Ever wanted to learn how to design your own PCB? How about building a website in exchange for a boba or frappuccino?
Or, have you been thinking about publishing your Congressional App Challenge submission on the App Store, but are worried about paying the publishing fee? We've got you covered.

Go on — build that project you've always wanted to.

Hack Clubbers come from all over the world. In 2024, we hosted Counterspell, a game jam that ran simultaneously in 40+ locations worldwide. This year, we'll be running Scrapyard worldwide, with a flagship hackathon hosted on March 1st-2nd - just one of many events this year built and organized by a team of teenagers at Hack Club.

No matter who you are, where you're from, or how experienced (or not!) you are at programming - you're welcome here.
