Join us to build apps, hardware, and community!
TreeHacks is Stanford University’s premier and largest hackathon. We bring together over 2000 students to Stanford every February to build the future. Sure, you’ll be hacking for 36 hours straight. But there will be yoga breaks. And laser tag. Lightsaber battles? Maybe even puppies. Whether you’re a seasoned veteran or just getting started, we’ve got your back every step of the way. *Stanford students are automatically accepted but need to RSVP
