We're huge-- and growing

PennApps is the largest student-run hackathon in the country. Last Spring we saw over 40 teams present their hacks, with over 180 students coming from 10 schools.

48 hours of hacking

The only thing you'll need to worry about when you get here is hacking. We'll take care of the rest. Breakfast, lunch, dinner, snacks, (energy) drinks, some awesome PennApps and sponsor swag, a place to sleep- all gratis.


Open to all students

PennApps is open to current undergraduate and graduate students at all schools. You don't have to be a computer science major, and you don't have to attend Penn (and we'll reimburse your bus fare to get here).

Get ready to impress

With $7000 + awesome trips in prizes for the top 3 teams, and over $5000 in other prizes, you have a lot to hack for. It's time to get serious.
