Most software showcases today are flooded with AI wrappers, ChatGPT clones, and prompt engineering demos. Hackathon builders are different. They ship real things under real pressure -- hardware that bends physics, protocols that rethink how money moves, tools that make developers faster, and products built for people who actually need them. This repo collects those projects. It pulls directly from the Devfolio API, organizes by theme, and updates every 24 hours so nothing gets buried.
