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. -

RESTinio
HTTP/WebSocket server C++14 library
RESTinio is a header-only C++14 library that gives you an embedded HTTP/WebSocket server. It is based on the standalone version of ASIO and is targeted primarily for the asynchronous processing of HTTP requests. Since v.0.4.1 Boost::ASIO (1.66 or higher) is also supported. Consider the task of writing a C++ application that must support some REST API, RESTinio represents our solution for that task. Server runs on the main thread, and responds to all requests with a hello-world message. Of course, you've got access to the structure of a given HTTP request, so you can apply complex logic for handling requests. Async request handling. Cannot get the response data immediately? That's ok, store the request handle somewhere and/or pass it to another execution context and get back to it when the data is ready. -

LaravelS
LaravelS is an out-of-the-box adapter between Laravel/Lumen and Swoole
LaravelS is an out-of-the-box adapter between Laravel/Lumen and Swoole. LaravelS uses Swoole's Synchronous IO mode, the larger the worker_num setting, the better the concurrency performance, but it will cause more memory usage and process switching overhead. If one request takes 100ms, in order to provide 1000QPS concurrency, at least 100 Worker processes need to be configured. Create WebSocket Handler class, and implement interface WebSocketHandlerInterface. The instant is automatically instantiated when start, you do not need to manually create it. -

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. -
