- We're expecting 300+ participants. We want to be the event for high school students this year. Come join us :) 


Our Mission

Hack3 is a global online hackathon that aims to enable high school students to learn computer science, with a broader message of "everyone can code" to target underrepresented demographics to improve diversity and inclusion of individuals in the computer technology space.

COVID-19’s effects have revealed great wealth inequalities in communities. More than ever, marginalized and impoverished communities need opportunities to lift themselves out of poverty.

At Hack3, we believe that providing educational opportunities to learn computer science, one of the highest paying job sectors, is the solution.

We hope that by bringing students of all backgrounds together, we will be able to foster innovation, creativity, and create new lifelong friendships for hackers.

In 2020, we connected 275 participants of all skill levels, to build novel projects that positively impacted the world. In 2021, we hosted over 335 participants. Last year, over 150 attended our free classes led by industry professionals to learn new skills. Over twenty mentors staffed our helpdesk to help participants when they needed help. Our judges, mentors, and workshop instructors have been affiliated with the likes of Stanford, Harvard, Amazon, NetApp, and Wikipedia. This year, with the support of Major League Hacking, we will elevate our performance to provide an even better experience for all. 


Free class for beginners!

To better help our beginner hackers, two of our organizers, Jonathan Lei and Eric Sun, will be running an Intro to Computer Science course from 8:00 PM to 9:00 PM EDT Monday through Friday. They're developing the course with help from Helm Learning, a nonprofit that has taught nearly 4k students computer science classes during the pandemic. They're also borrowing content from Major League Hacking's Localhost program. Learn about how to make the most of Hack3 from the organizers of it! It's designed to teach entry-level participants everything they need to get started! Computer science basics, APIs, databases, etc. We'll be posting recordings online, so feel free to watch those too if your schedule doesn't work.


Hack... 3! Hack... 3! Hack... 3! 

With the lessons learned from two years of running Hack3, we aim to host an even better hackathon this year. Happy hacking, and we hope Hack3 is a memorable starting point to your computer science journey! Register today! 


A valid submission is a software or hardware project fully produced only during the Hack3 hackathon, from start to finish. There are no limitations or guidelines to the project's concept. Projects may be submitted to other competitions as long as the participant only worked on the project during the Hack3 timeframe. 


Remember to include all your team member's names, up to 4 people.


Your Devpost submission will be posted on our "Submissions" tab, where others will be able to post feedback.
