Product Overview

eventlet

Description: Eventlet is a concurrent networking library for Python that allows developers to easily write highly scalable servers. It uses green threads to provide asynchronous I/O without having to deal with callback functions or program complexity.

Socket.io

Description: Socket.io is a JavaScript library that enables real-time, bidirectional and event-based communication between web clients and servers. It works by creating a persistent connection between the client and server that both can use to start sending data at any time, allowing for faster and more dynamic real-time web applications.
