Node.js vs. CodeIgniter vs. Dropwizard

Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

CodeIgniter is a proven, agile & open PHP web application framework with a small footprint. It is powering the next generation of web apps.

Dropwizard is a sneaky way of making fast Java web applications. Dropwizard pulls together stable, mature libraries from the Java ecosystem into a simple, light-weight package that lets you focus on getting things done.
