Show HN: Built live community stats into our blackjack app – built using Vapor

[pompeii]

We added a live global feed showing real-time stats across all players: total money wagered, active games, wins/losses, blackjacks hit, and win rates. Everything updates instantly as thousands of players make moves.

Built entirely in Swift—iOS app with SwiftUI and backend with Vapor. Full-stack Swift ecosystem handling WebSockets for sub-100ms latency. The consistency across the stack made development surprisingly smooth.
