Dev Builds Server-Authoritative Realtime Multiplayer Soccer Game in Browser with Claude Code
lavel0rz · reddit · 2026-11-08
A developer built browserball.io, a server-authoritative realtime multiplayer soccer game, entirely with Claude Code — even the trailer was made by Claude. Previous WebSocket attempts always suffered head-of-line blocking and packet loss; this time Claude helped prototype a WebTransport UDP-like data channel, delivering a fast-paced realtime physics game in the browser. The single server is US-based and free to play.
