    Kafka
    Kafka is a distributed, partitioned, replicated commit log service. It provides the functionality of a messaging system, but with a unique design.
    Firebase
    Firebase is a cloud service designed to power real-time, collaborative applications. Simply add the Firebase library to your application to gain access to a shared data structure; any changes you make to that data are automatically synchronized with the Firebase cloud and with other clients within milliseconds.
    Socket.IO
    It enables real-time bidirectional event-based communication. It works on every platform, browser or device, focusing equally on reliability and speed.
    Google Cloud Pub/Sub
    Cloud Pub/Sub is a fully-managed real-time messaging service that allows you to send and receive messages between independent applications. You can leverage Cloud Pub/Sub’s flexibility to decouple systems and components hosted on Google Cloud Platform or elsewhere on the Internet.
    SignalR
    SignalR allows bi-directional communication between server and client. Servers can now push content to connected clients instantly as it becomes available. SignalR supports Web Sockets, and falls back to other compatible techniques for older browsers. SignalR includes APIs for connection management (for instance, connect and disconnect events), grouping connections, and authorization.

    How developers use NATS and Pusher

    In the original prototype all the communication was handled by a backend server. Each client connected directly to the server using the socket.io library. This quickly proved to be messy and unreliable, especially on the cheap server being used to host it.

    Websockets proved to be a little more reliable, but still just as messy and not all browsers support them. That's when the project was switched over to use Pusher. Using Pusher has allowed all but the initial connection code to be off-loaded onto the client. Now instead of communicating through a self-hosted server, clients can communicate pretty much peer-to-peer over Pusher.
