A hackathon with a sting
HornetHacks packs everything great about a hackathon into a single Saturday. Show up with an idea (or none at all), find a team, build with help from mentors and workshops, and demo your project to judges before the day is out.
It's free, beginner-friendly, and made for high school students across Dallas–Fort Worth.
