Online Hackathons USA

16 upcoming online hackathons in the US

They run from June 2026 through to February 2027. 11 of the 16 carry no city at all; the other 5 name one on the card as well — hybrid events, and remote events run out of a city. Recurring themes include AI, AI Agents and High School. Organisers listing here include Seattle JS, Code Crunch Worldwide & GDG at FIU and Devpost, Inc. Dates, prizes and registration links on every listing, updated weekly.

what counts as these

A listing appears here when you can take part without being in the room: the organiser marked the event Online or Hybrid, or filed it under Online instead of a city. Hybrid events are included because they run a remote track — they keep their city on the card, so you can see which ones they are.
