Overview

Crikstars is a mobile app for following cricket as it happens — not one match at a time, but every match running at once, each with its own live scorecard.

Tournaments are modelled properly: groups, fixtures, standings and knockouts all update as results come in, so the app stays useful across a whole competition rather than a single game.

Group chat rooms sit alongside the score, which is where most of the traffic actually goes. Scores and chat share the same real-time transport so a wicket and the reaction to it arrive together.

The engineering problem

Score updates and chat both spike at the same instant — the moment a wicket falls. A single socket layer with per-match channels and fan-out through Redis keeps both flowing without one starving the other.

What it does

  • Real-time scoring across multiple concurrent matches
  • Tournament structures — groups, fixtures and standings
  • Group chat rooms attached to live matches
  • Push notifications for wickets, milestones and results
  • Built mobile-first for the way people actually watch
