Katamari (塊) Polyglot Asynchronous Web Server and Middleware Framework
Katamari is a Web Server and a Middleware Framework inspired by Rack (Ruby), Connect.js (Node.js), WSGI (Python) and Ring (Clojure). The asynchronous part is handled by Netty. And it is polyglot: written in Java with bindings for other languages (currently only Ruby).
