socket.io vs Gatsby

Socket.io is a JavaScript library for real-time web applications. It enables bidirectional and low-latency communication between web clients and servers. It is designed to be easy to use and provides a simple API for sending and receiving messages.

Gatsby is an open‑source framework that lets developers build blazing‑fast websites and apps using React, GraphQL, and modern web technologies. It compiles source files into static assets that can be deployed to any web host, delivering optimal performance and SEO out of the box. With a rich plugin ecosystem and seamless integration with headless CMSs and CI/CD platforms, Gatsby empowers agencies and developers to create scalable, secure, and highly maintainable web experiences while keeping the development workflow familiar and efficient.
