RSS/ATOM reader. No server backend required, all parsing is done in browser. No synchronization.
RSS Reader (RR) is chrome extension for reading news feeds. It is my attempt to recreate Google Reader which was discontinued some time ago. Because Chrome extension can make AJAX request to any domains, it is possible to create RSS reader completely without any server backend. This is interesting fact because no matter how many people will use it, there would be no need for more server resources. The downside is that storage is somewhat limited, currently to 5 MB so that RR does not actually store the feeds data. RR now can also read twitter feeds directly.
