MariHacks is Montreal’s first and largest 24-hour hackathon for CEGEP and High School students. We will bring together over 100 developers and technology enthusiasts to create revolutionary software projects. Meet fellow hackers, and learn new technologies.

Whether you're making your first app or have lots of experience, join us for an amazing day of hacking! We thrive to foster a learning environment and introduce new programmers to hackathons. 

Feel free to reach out to execs and other participants for any questions at the event!

MariHacks is going virtual this year!

Judging Criteria

  • Technology
    How technically impressive was the hack? Was the technical problem the team tackled difficult? Did it use a particularly clever technique or did it use many different components? Did the technology involved make you go "Wow"?
  • Design
    Did the team put thought into the user experience? How well designed is the interface? For a website, this might be about how beautiful the CSS or graphics are. For a hardware project, it might be more about how good the human-computer interaction is.
  • Completion
    Does the hack work? Did the team achieve everything they wanted?
  • Learning
    Did the team stretch themselves? Did they try to learn something new? What kind of projects have they worked on before?
