Arbiter Hacks V1

About the challenge

Arbiter Hacks V1 runs two parallel tracks. Pick one when you register, or switch before the submission deadline. You may only submit to one track.

General Track: Build anything. Any language, any stack, any idea. This track rewards technical ambition and execution, regardless of subject.

Theme Track, Rethinking Waste: Build something that helps people or systems reduce, sort, or recycle waste more effectively. Examples include a tool that identifies whether an item is recyclable, an app that routes food waste to donation, a hardware or vision system that sorts materials, or a dataset or model that improves recycling accuracy. If it moves the needle on waste, it fits.

The tracks are judged separately, against separate rubrics, for separate prizes. A polished General submission and a high-impact Theme submission compete only within their own track.

Get started

1. Register and pick a track.
