Porra Mundial
World Cup predictions to compete with friends
World Cup prediction web game: guess the scores and climb your group leaderboard. JavaScript + Supabase, deployed on Vercel.
The problem
Every World Cup we ran the pool by hand in spreadsheets: messy to update and easy to argue over the scoring.
The solution
A web app where each friend enters their predictions and the leaderboard updates automatically in real time. Vanilla JavaScript on the front with Supabase (Postgres + auth) as the backend, deployed on Vercel.
