Hey HN - long-time reader, first-time Show HN. I built a sports app called Arbitration[1] primarily for experiencing live professional games. The original itch was pretty simple: during close or rivalry games I’d constantly flip between two team game threads on Reddit to see how each side was reacting to the same play. Arbitration puts both fanbases’ live reactions in one place, synced to the game clock. It doesn’t generate opinions or takes — it just curates what fans are already saying, in real time. Feel free to checkout the first NFL playoff game of the year, Rams @ Panthers: https://www.app.arbi.gg/scores/nfl/20260110-8-5 For folks curious about the tech: - Agents are used to curate and rank live fan posts (not generate content) - Live DraftKings props come from a websocket snooper[2] - Google Gemini is used only to structure and summarize live prop data - Rust backend, React frontend, anonymous sessions, no accounts. - Mostly built for myself, but figured others here might enjoy it. - iOS app coming soon! Happy to answer questions :) - [1] https://arbi.gg - [2] DraftKings websocket snooper: https://github.com/stonehedgelabs/snuper |
