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

A hackathon is where you turn your crazy ideas into real projects. We provide hardware, mentors, fun activities, speakers, workshops, food, friends, and so much more. You take care of hacking; we’ll take care of you.
Due to new guidance from Stanford administration, TreeHacks 2022 will take place virtually.
TreeHacks applications are open to any enrolled college student (undergrad or grad) from all over the world. All current Stanford students that register by appropriate deadlines will be guaranteed admission.
TreeHacks is the perfect time and place to learn. We provide starter code “hack packs,” as well as beginner-friendly workshops and mentors to help you build something you can be proud of.
Not a problem! We’ll have team-forming activities to help you find teammates and idea brainstorming sessions for all our challenges. Some of our best hacks have been from teams that met and formed an idea on the spot!
Anything your heart desires! Hardware, web, mobile, gaming, VR...you name it, we’ll support it. We have five challenges that will have extra resources, sponsored challenges, and other events to inspire you.
TreeHacks is free for all admitted hackers! It’s our pleasure to bring our virtual workshops, swag, and prizes to our hackers without any cost on your end. We're committed to making TreeHacks accessible!
TreeHacks abides by this Code of Conduct, adapted from the Hack Code of Conduct. Every TreeHacks applicant must agree to this Code of Conduct to be considered for admission. TreeHacks is a safe place where everyone is welcome <3.
