Hey HN! Recently Meta wrapped up their Global Developer Hackathon (https://dev.meta.ai/events/global-hackathon) which had a $1M prize pool (!!): 34K developers applied, 20K accepted, and over 5K projects were submitted.

With this crazy volume, it was infeasible to rank or even shortlist the best projects with human review. On the other hand, AI scoring against a rubric led to disappointing results.

In an effort to surface and spotlight the best projects, I built MetaArena (https://meta-hackathon.com/). It compares just two projects head-to-head, let's you pick which you thought was the stronger project, and places them on a leaderboard using the same algo platforms like LLMArena and DesignArena use to rank AI models (Bradley-Terry).

Check it out, at the very least I hope you find a cool project or two here that inspire you. Lmk if you have any feedback on the arena/leaderboard!
