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](https://alexhultman.medium.com/serving-100k-requests-second-from-a-fanless-raspberry-pi-4-over-ethernet-fdd2c2e05a1e)** and at least **[10x that of Socket.IO](https://medium.com/swlh/100k-secure-websockets-with-raspberry-pi-4-1ba5d2127a23)**. It is also the built-in **[web server of Bun](https://bun.sh/)**.
