Meteor vs. CodeIgniter vs. Tornado

A Meteor application is a mix of JavaScript that runs inside a client web browser, JavaScript that runs on the Meteor server inside a Node.js container, and all the supporting HTML fragments, CSS rules, and static assets.

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

By using non-blocking network I/O, Tornado can scale to tens of thousands of open connections, making it ideal for long polling, WebSockets, and other applications that require a long-lived connection to each user.
