MetaArena launches: comparing and ranking 5,353 hackathon projects
Understand this story
Developer ohong has released MetaArena, which uses pairwise comparisons plus the Bradley-Terry algorithm to rank the 5,353 projects in Meta's global developer hackathon. The hackathon has a $1 million prize pool, with 34,000 registrants and 20,000 selected. ohong says manual review could not complete the screening, and having AI score projects against the judging criteria did not work well, so they switched to having users choose the stronger project pair by pair, helping high-quality works gain exposure.

- Hacker News AIShow HN: MetaArena – Compare & Rank 5,353 Meta Global AI Hackathon Projects
The author built MetaArena, a site that presents two projects from Meta's Global Developer Hackathon head-to-head and lets users pick the stronger one, ranking them on a leaderboard using the Bradley-Terry algorithm used by LLMArena and DesignArena. The hackathon had a $1M prize pool, 34K applicants, 20K accepted developers, and over 5K submitted projects, which made human review infeasible and AI rubric scoring disappointing.
