Pusher

Pusher makes realtime APIs that power not just Christmas trees but chat, trading, maps, games, and any other realtime apps you can think of. On the server-side, you’ll help us use Go, Kubernetes, Ruby, and Redis to handle millions of connections and send 300K messages every second. On the client-side, you’ll help us build great developer experiences with SDKs for JavaScript, Swift, Kotlin, Unity, and many more platforms.
