Thin

If you're in search of a Ruby web server that truly stands out, then look no further than Thin. This remarkable software glues together three of the best Ruby libraries in web history, resulting in an unparalleled experience for users.

First and foremost, Thin features the Mongrel parser - the very root of Mongrel's speed and security. This means Thin is exceptionally fast and secure, providing users with the peace of mind they need when running a web server.

Additionally, Thin also includes Event Machine, a network I/O library known for its scalability, performance and stability. This aspect of Thin allows it to operate smoothly no matter how many users are accessing the server at any given time.

Finally, Thin makes use of Rack - a minimal interface that connects webservers and Ruby frameworks. This interface makes it easy for developers to create custom web applications that integrate seamlessly with Thin.

Overall, Thin is one of the most secure, stable, fast, and extensible Ruby web servers currently on the market. And, because it's bundled as an easy-to-use gem, it's never been easier to start using Thin for your own purposes. Whether you're a seasoned developer or just starting out, Thin is a must-have tool in your arsenal.
