What is a hackathon?

Hackathons are where your crazy idea becomes reality. Students work in teams of up to five for 36 hours to create something amazing. Build anything—there are no restrictions on what you can create. Dive in and make the most incredible thing you can alongside fellow creators.


Who can attend?

Any high schoolers can attend GunnHacks. Unfortunately, we cannot allow college students or middle schoolers to attend this time around.


What if I don’t know how to code?

All students regardless of coding ability or experience are welcome. Hackathons are a great place to learn, so come and build your first app, website, or anything else! We’ll also have workshops for you to start off or learn something new.


What can I build?

Web, mobile, hardware, you name it—any type of project is welcome. Projects will be judged based on creativity, technical difficulty, polish, and utility by a panel of industry judges.


How big should teams be?

We highly encourage you to build with a team. Teamwork is deeply rooted in the hacking ethos, and you’ll have a better time building with your brightest peers. Teams shall consist of no more than four people. But don’t worry if you don’t have a team before the event—we will have a team-formation session Friday night.


What if I don’t have a team?

No problem! Many hackers do not have a fully-formed team or hack concept before the event begins. We will be hosting team-forming activities after hacking begins to help you find the perfect match. If you’re a first-time hacker, there will be many others looking for team members with whom you can work.


How much does it cost?

Participation in GunnHacks is completely free. However, due to the online nature of the event, we recommend ownership of a computer and access to the internet.


Do I have to work the whole time?

No, not at all! We will have fun activities and workshops you can participate in when you want to take a break.


Where is GunnHacks?

Due to the pandemic, GunnHacks 7.0 will be held online this year. As we get closer to the event more details will be posted.


When does registration close?

Registration closes on February 12th, at 11:59pm Pacific Time, when the hackathon begins.
