WK 2026 Prediction Pool
WK 2026 Prediction Pool live
An office World Cup pool I built instead of paying Scorito €200 per group: idea to live in about an hour, now used by 30 colleagues. Live scores, match minutes and goalscorers auto-import from a public API, and the leaderboard reshuffles in real time during matches. Weekly bonus rounds, closest-guess metagames, fully customizable scoring. Free, no ads.
How: React + Vite on Netlify Functions & Blobs, fully serverless, no database. Live match data pulled from a public football API.
