Launch your Legacy at HackIllinois. Join us at UIUC’s 13th international premier hackathon for a weekend of innovation, learning, and competition. Attendees will embark on a 36-hour weekend journey to develop projects for company-sponsored tracks, meet company recruiters, and compete for cash prizes. We also offer project support through workshops, mentors, and more. We cater from beginner to advanced skill levels and are open to anyone 18 and over.

 

Beyond project development, HackIllinois offers an array of fun activities: 

  • An Astral Exhibiton 
  • Coding challenges
  • Relaxing breaks
  • Frequent snack times to keep your energy high!

 

This year, continuing HackVoyagers! Aimed at experienced coders, the HackVoyagers path provides a more competitive hackathon experience with increased prize values, including a grand prize of $5,000. Voyagers enjoy privileges like networking opportunities with sponsors and a chance to present in a thrilling Shark Tank-style project showcase.

While HackVoyagers caters to advanced coders, the standard HackIllinois path remains a welcoming space for all skill levels. Both paths are eligible for company-sponsored tracks, company workshops, and all fun activities. Our commitment to inclusivity and learning ensures a fulfilling experience for everyone. Ready to code, create, and launch your legacy?
