Kanso is a framework for creating web applications which run on CouchDB. You don't need anything else in your stack, meaning apps are easy to deploy and easy to distribute.
The Kanso framework was designed for rapid development and code maintainability. Because it only requires CouchDB to host an app, you can write web apps which run on Windows, Mac, Linux, and even mobile devices!
