µWebSockets.js is a web server bypass for Node.js that reimplements eventing, networking, encryption, web protocols, routing and pub/sub in highly optimized C++. As such, µWebSockets.js delivers web serving for Node.js, 8.5x that of Fastify and at least 10x that of Socket.IO. It is also the built-in web server of Bun.
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...
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). ...
