    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.

    WebSocket Kit

    WebSocket Kit

    WebSocket client library built on SwiftNIO

    WebSocket client library built on SwiftNIO. WebSockets allow for two-way communication between a client and server. Unlike HTTP, which has a request and response pattern, WebSocket peers can send an arbitrary number of messages in either direction. Vapor's WebSocket API allows you to create both clients and servers that handle messages asynchronously.

    obs-websocket

    obs-websocket

    Remote-control of OBS Studio through WebSocket

    obs-websocket is the WebSocket control interface for OBS Studio, enabling external applications to monitor and control OBS remotely. It lets developers build tools that change scenes, control streaming or recording, manage sources, adjust inputs, read status information, and automate production workflows. The plugin is included by default in OBS Studio 28 and newer, so most modern OBS users do not need a separate installation. It exposes a structured request, response, and event protocol that can be used by dashboards, stream decks, bots, automation scripts, remote controllers, and broadcast systems. obs-websocket is especially useful for streamers, developers, live-event teams, and studios that need programmable control over OBS. It turns OBS from a manual desktop tool into an automation-ready production engine.

    IXWebSocket

    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.

    ws

    ws

    Tiny WebSocket library for Go

    Zero-copy upgrade. No intermediate allocations during I/O. Low-level API which allows building your own logic of packet handling and buffers reuse. High-level wrappers and helpers around API in wsutil package, which allow to start fast without digging the protocol internals. Existing WebSocket implementations do not allow users to reuse I/O buffers between connections in clear way. This library aims to export efficient low-level interface for working with the protocol without forcing only one way it could be used. Library is tagged as v1* so its API must not be broken during some improvements or refactoring. Example applications using ws are developed in separate repository ws-examples. We can apply the same pattern to read and write structured responses through a JSON encoder and decoder.Zero-copy upgrade helps to avoid unnecessary allocations and copying while handling HTTP Upgrade request.

    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.

    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.

    WebSocket ++

    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.

    websocketd

    websocketd

    Turn any program that uses STDIN/STDOUT into a WebSocket server

    websocketd is the WebSocket daemon. It takes care of handling the WebSocket connections, launching your programs to handle the WebSockets, and passing messages between programs and web-browser. If you can run your program from the command line, you can write WebSocket endpoints. Just read incoming text from stdin and write outgoing text to stdout. Messaging is simple. Each inbound WebSocket connection runs your program in a dedicated process. Connections are isolated by process. Available for Linux, OSX, Windows, FreeBSD, OpenBSD and Solaris. Serves your static HTML, JavaScript, etc. Route different URLs to different programs. Dynamic generate content over HTTP too. Out-of-the-box support for serving content using HTTPS and WSS. Restrict which pages can make WebSocket connections. Interact with your WebSocket programs before you've built your frontend.

    C# Websocket Implementation

    Fleck is a lightweight WebSocket server implementation for C# applications. It gives developers a simple way to accept WebSocket connections without requiring inheritance-heavy frameworks, containers, or extra server dependencies. The project is designed to be easy to embed inside desktop apps, services, prototypes, tools, and custom .NET servers. Fleck exposes straightforward callbacks for connection open, close, message, binary, ping, and pong events. It does not depend on HttpListener or HTTP.sys, which makes it usable in environments where those Windows components are not appropriate. It is best suited for developers who need a small, direct WebSocket server layer rather than a full web framework.
