HopHacks is the bi-annual hackathon hosted at Johns Hopkins University in Baltimore, Maryland. This event brings engineers, designers, and entrepreneurs together to explore new ideas, compete for prizes, and create amazing applications. For 36 hours, students work in teams of up to 4 to bring a software or hardware idea to life.

Teams start working on their hacks (at 9:00 PM) after the Friday evening kickoff event and continue working until Sunday morning (9:00 AM). All submissions MUST be made on Devpost.

All of the prizes, including sponsored prizes, will be judged and announced at the presentation.

Any university student, regardless of university, may participate. Graduate and undergraduate students from all departments and divisions are welcome. 

You must register online and receive email confirmation before attending. Please be prepared to show your University ID upon check-in.


At the end of the hackathon, your team can submit a project on DevPost. Your project will then be judged during your science fair style presentation during the presentation time.
