    µWebSockets

    µWebSockets

    Compliant web server for the most demanding of applications

    Being meticulously optimized for speed and memory footprint, µWebSockets is fast enough to do encrypted TLS 1.3 messaging quicker than most alternative servers can do even unencrypted, cleartext messaging. Furthermore, we partake in Google's OSS-Fuzz with a ~95% daily fuzzing coverage with no sanitizer issues. LGTM scores us flawless A+ from having zero CodeQL alerts and we compile with pedantic warning levels. µWebSockets is written entirely in C & C++ but has a seamless integration for Node.js backends. This allows for rapid scripting of powerful apps, using widespread competence. We've been fully standards compliant with a perfect Autobahn|Testsuite score since 2016. Companies with everything to lose rely on µWebSockets on a daily basis - we power the trading APIs of Bitfinex.com & Kraken.com, handling volumes of multiple billions of USD every day. Other companies include Trello, where µWebSockets is serving their 50 million users with real-time board updates.

    Socket.IO-client Java

    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.

    Rhubarb

    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.

    Autobahn|Python

    Autobahn|Python

    WebSocket and WAMP in Python for Twisted and asyncio

    Autobahn Python is a networking library for building Python applications that use WebSocket and WAMP. It supports both Twisted and asyncio, giving developers flexibility depending on their preferred Python event framework. The WebSocket layer enables bidirectional real-time messaging between clients and servers. The WAMP layer adds routed remote procedure calls and publish-subscribe messaging for distributed applications. Autobahn Python is useful for dashboards, IoT systems, collaborative apps, backend services, messaging platforms, and applications that need real-time communication across components. It works especially well with a WAMP router such as Crossbar.io when building routed multi-service systems.

    FACIL.IO

    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.

    Gorilla WebSocket

    Gorilla WebSocket

    Fast, well-tested and widely used WebSocket implementation for Go

    Gorilla WebSocket is a Go implementation of the WebSocket protocol. The Gorilla WebSocket package provides a complete and tested implementation of the WebSocket protocol. The package API is stable. An application can also send and receive messages using the io.WriteCloser and io.Reader interfaces. To send a message, call the connection NextWriter method to get an io.WriteCloser, write the message to the writer and close the writer when done. To receive a message, call the connection NextReader method to get an io.Reader and read until io.EOF is returned. The WebSocket protocol distinguishes between text and binary data messages. Text messages are interpreted as UTF-8 encoded text. The interpretation of binary messages is left to the application. The Gorilla WebSocket package passes the server tests in the Autobahn Test Suite using the application in the examples/autobahn subdirectory.

    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.
