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. -

WebSocket ++
C++ websocket client/server library
WebSocket++'s goal is to provide a flexible set of tools for building a wide variety of WebSocket based applications wrapped by low or zero overhead abstractions. It is not opinionated. If something can be practically replacable (with low overhead) based on the user's preference then it is. It accomplishes this via a policy based design built using C++ template metaprogramming. WebSocket++ is a cross platform open source (BSD license) header only C++ library that implements RFC6455 (The WebSocket Protocol) and RFC7692 (Compression Extensions for WebSocket). It allows integrating WebSocket client and server functionality into C++ programs. In its most common configuration full featured network I/O is provided by the Asio Networking Library. Bundled config packages provide sane defaults so most users can get started quickly. As they understand their solution better and want to optimize, the default components can be reconfigured or replaced entirely and transparently. -

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. -

SNI Cloudflare MASQUE All Countries
Value Added Warp over WebSocket via CDN Tunnel
UDP Over SSL Tunnel UDP Over SSL Tunnel is a free SSL tool with SNI Host (Spoof Host) support ( SSL Injector ). Warp-over-WebSocket-CDN Bypass ISP throttling and DPI by tunneling Cloudflare Warp traffic over WebSocket with Host Header spoofing through major CDN networks (CloudFront / Cloudflare / Akamai). Platform Protocol Tunnel License What It Does Many ISPs throttle or block VPN traffic using Deep Packet Inspection (DPI). Warp-over-WebSocket-CDN wraps WireGuard UDP inside a WebSocket connection with a spoofed Host header, routing traffic through major CDN edge networks (CloudFront, Cloudflare, or Akamai). To any firewall or DPI system, the traffic looks like a legitimate WebSocket upgrade to a CDN-hosted domain. Result: Full Cloudflare Warp speed and privacy, even on heavily restricted networks — including campus, corporate, and ISP-level DPI systems. -

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. -

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. -

Sente
Realtime web comms for Clojure/Script
Sente is a small client+server library that makes it easy to build reliable, high-performance realtime web applications with Clojure + ClojureScript. Bidirectional a/sync comms over both WebSockets and Ajax (auto-fallback). It just works, auto keep-alives, buffering, protocol selection, reconnects. Efficient design incl. transparent event batching for low-bandwidth use, even over Ajax. Send arbitrary Clojure vals over edn or Transit (JSON, MessagePack, etc.). Make-channel-socket! and you're good to go. Automatic, sensible support for users connected with multiple clients and/or devices simultaneously. Realtime info on which users are connected over which protocols (v0.10.0+). Flexible model: use it anywhere you'd use WebSockets/Ajax/Socket.IO, etc. Standard Ring security model: auth as you like, HTTPS when available, CSRF support, etc. Fully documented, with examples. Small codebase: ~1.5k lines for the entire client+server implementation. -

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. -

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
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. -
