about
We're building a comprehensive hackathon directory for the United States — a single place to find every build weekend, jam and design challenge in the country, from the Bay Area to Boston.
We aggregate events from Eventbrite, Devpost, Luma, Meetup, and direct submissions so you never miss a hackathon happening near you.
Have a hackathon to list? submit it here — live within 24 hours.
faq
How do I submit a hackathon?+
Use the Submit Hackathon button in the header. Give us the name, dates, city, registration link and a banner if you have one — we review and publish within 24 hours.
Is it free to list a hackathon?+
Yes. Standard listings are free forever. Get Featured is a paid option that pins your event to the top of the directory.
How often is the directory updated?+
Weekly. We sweep Eventbrite, Devpost, Luma and Meetup once a week, and direct submissions are reviewed the same day.
What cities are covered?+
Ten hub cities — San Francisco, New York, Boston, Los Angeles, Seattle, Austin, Chicago, Washington DC, Denver and Atlanta — plus the metros that feed them, so events in Palo Alto, Brooklyn, Cambridge, Santa Monica, Bellevue, Evanston, Arlington, Boulder and Decatur all show up under their nearest hub. Cities outside those catchments, like Dallas, Miami and Seattle's far neighbours, keep their own name rather than being filed under a hub hundreds of miles away. Online-only events get their own listing.
Can I attend online hackathons?+
Yes. Filter by Online to see remote-friendly events, including ones run from outside the US that accept American participants.
