socket.io
Realtime application framework (Node.JS server)
socket.io is a JavaScript library that allows for realtime, bi-directional communication between web clients and servers. It is composed of two parts: a Node.js server and a JavaScript client library that runs in the browser. socket.io is focused on both reliability and speed, delivering an immensely powerful, fast and yet easy to use realtime engine that’s used by just about everyone: from Microsoft Office and Zendesk to hackathon winners and small startups. It’s considered one of the most depended-upon npm modules, and works on every platform, browser or device. -

IXWebSocket
websocket and http client and server library, with TLS support
IXWebSocket is a C++ library for WebSocket client and server development. It has minimal dependencies (no boost), is very simple to use and support everything you'll likely need for websocket dev (SSL, deflate compression, compiles on most platforms, etc...). HTTP client and server code is also available, but it hasn't received as much testing. It is been used on big mobile video game titles sending and receiving tons of messages since 2017 (iOS and Android). It was tested on macOS, iOS, Linux, Android, Windows and FreeBSD. Two important design goals are simplicity and correctness. -

SockJS-client
WebSocket emulation and Javascript client
SockJS is a browser JavaScript library that provides a WebSocket-like object. SockJS gives you a coherent, cross-browser, Javascript API which creates a low latency, full duplex, cross-domain communication channel between the browser and the web server. Under the hood SockJS tries to use native WebSockets first. If that fails it can use a variety of browser-specific transport protocols and presents them through WebSocket-like abstractions. SockJS is intended to work for all modern browsers and in environments which don't support the WebSocket protocol, for example, behind restrictive corporate proxies. SockJS-client does require a server counterpart, such as SockJS-node, which is a SockJS server for Node.js. The API should follow HTML5 Websockets API as closely as possible. All the transports must support cross domain connections out of the box. It's possible and recommended to host a SockJS server on a different server than your main web site. -

Tyrus
Eclipse Tyrus is the open source JSR 356 - Java API for WebSocket
Eclipse Tyrus is the open source JSR 356 - Java API for WebSocket reference implementation for easy development of WebSocket applications.Eclipse Tyrus is also a Jakarta WebSocket 2.0 compatible implementation. WebSocket protocol defined by IETF provides bi-directional communication between the server and the remote host. The pros are mainly the ability to communicate both ways, low latency and small communication overhead. Therefore Tyrus and WebSocket in general are suitable for web applications that require sending a huge volume of relatively small messages like online games or market ticker broadcasting. -

AnyCable
Polyglot replacement for Ruby WebSocket servers with Action Cable
Notifications, chats, real-time updates, GPS trackers, collaboration tools, and other real-time features are essential for every modern app. And you should be able to build them in the comfort of your core framework: owning the data, using resources efficiently, and writing clean, maintainable code. AnyCable transforms your Rails application’s real-time performance, making it on par with Go, Elixir, and Node.js–based solutions so you can focus on implementing the business logic. Scale efficiently with AnyCable by leveraging its much lower RAM usage and better CPU utilization than Action Cable. Like with any data, being strategic when handling real-time data is super important. With AnyCable, you remain the owner: you store and access all the data directly, and you never send it to a 3rd-party. Simple and secure. -

GraphQL WebSocket
Coherent, zero-dependency, lazy, simple, GraphQL
Coherent, zero-dependency, lazy, simple, GraphQL over WebSocket Protocol compliant server and client. Messages are represented through the JSON structure and are stringified before being sent over the network. They are bidirectional, meaning both the server and the client must conform to the specified message structure. Connection is a connection within the established socket describing a "connection" through which the operation requests will be communicated. The server can close the socket (kick the client off) at any time. The close event dispatched by the server is used to describe the fatal error to the client. The client closes the socket and the connection by dispatching a 1000: Normal Closure close event to the server indicating a normal closure. -

Ratchet WebSocket
Asynchronous WebSocket server
Ratchet is a loosely coupled PHP library providing developers with tools to create real time, bi-directional applications between clients and servers over WebSockets. Write your own chat (aka "Hello World!" for sockets) application in a matter of minutes. After understanding "the new flow", event driven programming, compared to traditional HTTP request/response - writing any application on top of Ratchet becomes fast and easy. Ratchet provides many components for you to pick and choose from to easily add functionality. The component architecture allows you to focus on functionality with the ability to reuse and add or remove other component functionality. Ratchet is fully PSR-4 compliant, so it naturally plays well with others. Leveraging components from Symfony2, development should feel similar to many. Ratchet passes all WebSocket tests to ensure it works on all supported browsers. -

Rhubarb
A WebSocket library optimized for multiplayer JS games
Rhubarb is a lightweight WebSocket library for multiplayer HTML5 games. It is originally designed to be used by the ROYGBIV Engine. However, it can be used outside of ROYGBIV as well. Javascript is slow, therefore we want to have as much main-process-power as we can in order to do game related calculations, graphics rendering and achieving 60 FPS. For multiplayer games achieving 60 FPS gets even more complicated given that transferring data over WebSockets is a slow operation. It also triggers GC activity by copying the transferred data (if JSON is the preferred way), which eventually slows down the main thread as well. -

Socket.IO-client Java
A Socket.IO client library for Java
This is the Socket.IO Client Library for Java, which is simply ported from the JavaScript client. The latest artifact is available on Maven Central. There are several ways to handle events that are transmitted between the server and the client. Add the listener function to the end of the listeners array for the event named eventName. Add a one-time listener function for the event named eventName. Remove the specified listener from the listener array for the event named eventName. Remove all listeners for the specific eventName. Remove all listeners (for any event). Besides emitting and listening to events, the Socket instance has a few attributes that may be of use in your application. Each new connection is assigned a random 20-characters identifier. -

Wslay WebSocket Library
WebSocket library written in C.
Wslay is a WebSocket library written in C. It implements the protocol version 13 described in RFC 6455. This library offers 2 levels of API: event-based API and frame-based low-level API. For event-based API, it is suitable for non-blocking reactor pattern style. You can set callbacks in various events. For frame-based API, you can send WebSocket frame directly. Wslay only supports data transfer part of WebSocket protocol and does not perform opening handshake in HTTP. Wslay does not perform any I/O operations for its own. Instead, it offers callbacks for them. This makes Wslay independent on any I/O frameworks, SSL, sockets, etc. This makes Wslay protable across various platforms and the application authors can choose freely I/O frameworks. -

FACIL.IO
Your high performance web application C framework
facil.io is an evented Network library written in C. facil.io provides high performance TCP/IP network services by using an evented design that was tested to provide an easy solution to the C10K problem. facil.io includes a mini-framework for Web Applications, with a fast HTTP / WebSocket server, integrated Pub/Sub, optional Redis connectivity, easy JSON handling, Mustache template rendering and more nifty tidbits. facil.io powers the HTTP/Websockets Ruby Iodine server and it can easily power your application as well. facil.io is easy to code with and aims at minimizing the developer's learning curve. In addition to detailed documentation and examples, the API is unified in style and the same types and API used for HTTP requests is used for JSON and Mustache rendering - so there's less to learn. facil.io should work on Linux / BSD / macOS (and possibly CYGWIN) and is continuously tested on both Linux and macOS.
