What is it

Build something this summer

Spend your summer evenings and weekends building a project you actually care about, then show it off and win merch.

Summ3r Cod3 runs through July and August. You can build ANY project you want — a web app, a game, an AI experiment, an Arduino build, literally anything. The goal is to ship something and share it with the community.

Not sure what to build? Some ideas:

That app you keep complaining doesn't exist
Something to help with your hobby
A game your friends might actually play
A tool that makes your coding life less painful
Something weird with AI
That Arduino project collecting dust in your drawer

How to join

It's easy

Pick a project, build it over summer, submit by August 30th.

Pick something fun to build — whatever interests you
Code away — spend your summer evenings and weekends on it
Share your progress — show us what you're working on, even the messy parts
Finish by August 30th — or at least get it to a showable state

You can ask questions in Discord throughout the summer, join casual check-ins to show progress, and get help from other participants when you're stuck.

FAQ

Common questions

Can my friends and I work together?
Totally! Just make sure everyone who wants a shirt meets the requirements.

I already started something, can I use that?
Sure, but you need to actually work on it during the summer. We can tell the difference!

Do I need to be some coding genius?
Definitely not! We've seen great projects from beginners. Just build something YOU think is cool.

What programming language should I use?
Whatever you want! Use what you know or what you want to learn.
