For 36 hours on March 31st - April 2nd, HackPrinceton will bring together 500 developers and designers from across the country to create incredible software and hardware projects.

At HackPrinceton, you’ll meet fellow hackers, learn new technologies, and hone your skills alongside seasoned mentors. We'll have free food, swag, workshops, mentorship, prizes, games, and more. Come with or without a team or an idea, and we'll inspire you to build something incredible.


  • All hacks must be built by accepted, confirmed, and checked-in HackPrinceton attendees. (This includes registered and checked-in Princeton students.)
  • Teams must consist of no more than four members.
  • Hackers must be a current student, or have left school within the past year, and present enrollment identification (i.e. student ID) to a HackPrinceton organizer if asked.
  • Due to university liability requirements, individuals must be at least 18 years old.


Submissions are due on Devpost by 9:00 AM on Sunday, April 2nd. After you submit, you can edit your submission until the deadline, so you are encouraged to begin your submission early. We are not able to accommodate late submissions.

You must include videos, photos, or screenshots of the working product and a link to the source code (GitHub, etc.) of your project.

Do you want your hacking to make a difference to millions of lives around the world? Join the AI for Good Foundation's Global Food Security Challenge! By making use of extensive crop data, plant genetics, soil, climate, and more, create new tools and analysis that help farmers and decision makers to make better decisions about what to grow, where, and the logistics surrounding it. Our world is running out of cropland. We’ll add 2 billion more people by the year 2050, but we’re currently using our arable land and water 50 percent faster than the planet can sustain. At the same time, the crops farmers plant face an unprecedented set of obstacles due to increasingly limited growing conditions and climate change. How will we be able to grow enough food to meet world demand?

Data is immediately accessible by registering at:

Our forum will be staffed to answer questions throughout the competition:

Judging Criteria

  • Originality
    How original is the idea? Is it simply a repackaging of a previous project or is it something that has never been done before? Projects can also blend two concepts together in a refreshing new way.
  • Design
    Is the project something that looks and feels polished? Is the user experience and interface smooth and well-designed?
  • Technical Difficulty
    Does the project take on technical challenges? What parts of the project did your team invent, and how did you build upon existing tools and technologies?
  • Enjoyment
    Is the project zany, interesting or just plain amusing? Will it bring a smile to the face of those who see it, whether they are adults, teenagers or little kids?
  • Usefulness
    Can this hack be used in real life to better somebody's life? Is it enough to justify people wanting to use it?
