Rendr
Render your Backbone.js apps on the client and the server
..., and models. This enables us to build interactive, native-style single-page apps, but splitting your app into two distinct codebases (often using different languages for client and server) also creates challenges for performance, maintainability, and SEO. Rendr is intended to be a building block along the way to this envisioned future of web apps that can be run on either side of the wire according to the needs of your application.
