Realtime

WebSocket

A full-duplex communication protocol over a single TCP connection, standardized by the IETF as RFC 6455 and defined in the WHATWG WebSocket API on the client side. WebSocket is the most widely deployed realtime protocol on the web — used for chat, multiplayer, live dashboards, collaboration, and as the carrier for higher-level realtime SDKs from Ably, Pusher, PubNub, Phoenix Channels, Socket.IO, and others.
