EcilyShow up with nothing.
Leave with something that works.
Mango Hacks is a free, one-day hackathon for high-school and early-college students across the Bay Area.
Built for first-timers
Workshops start from zero and mentors stay on the floor all day.
Everything is covered
Meals, snacks, stickers, and hardware to borrow. Free.
Judged by builders
Working engineers and founders give feedback and judge demos.
A real office, not a school gym.
Zoho Corporation is hosting us in Pleasanton. One room, one day, and everything you need already in it.

Food, and the first wall almost everybody hits.
Mentor sweep
Engineers walk the floor, unstick projects, and answer the dumb questions for free.

Last push, then everything gets locked.
Demos
Every team presents to real judges.
Awards and closing
Trophies, photos, and the group chat that outlasts the day.
