Jetty

Jetty is a lightweight, open-source Java-based web server and servlet container that provides HTTP and WebSocket services. It is designed for high-performance, scalable, and embeddable applications, often used in microservices, cloud environments, and development tools. Jetty supports the Java Servlet API, WebSocket, HTTP/2, and other web standards, making it a versatile choice for building and deploying web applications.

Also known as: Eclipse Jetty, Jetty Server, Jetty Servlet Container, Jetty HTTP Server, Jetty Web Server

Why learn Jetty?

Developers should learn Jetty when building Java-based web applications that require a fast, embeddable server, such as in microservices architectures, development environments (e.g., integrated with IDEs like Eclipse), or resource-constrained systems. It is particularly useful for scenarios where low latency and high concurrency are critical, like real-time applications using WebSocket, or when deploying lightweight standalone apps without a full application server.
