Web development has seen a huge innovative jump in the last years. Frameworks such as Ruby on Rails or node.js and several other frameworks have changed the landscape of the CGI and PHP based web considerably. New programming paradigms have emerged to make web apps managable to facilitate a clean application design. Node.js was the first to succeed in bringing the performance of asynchronous I/O to the masses. With vibe.d we are trying to bring the highest performance possible together with a programming interface that is as clean as possible. At the same time the choice of D as the programming language leads to code that provides much less potential for errors thanks to it's comprehensive static type system. Still, D's clean syntax gives you the same lean programming experience as in dynamically typed scripting languages. The combination is a very fast and practical system that provides a solid basis for many typical web applications and services, as well as non-web services. It st
