IPython notebooks run in the browser, but (usually) don't use a remote server. This medium - html/js - is great for analysis work with lots of image-processing/plotting/reporting, etc. but very difficult to build out a full app in it because it lacks any of the normal IDE find and refactor tools. Also, the .ipynb file storage format tends to obscure finding code within directories.
