One thing I liked about Piwik was their API documentation. Short and simple, and the examples are using actual data, meaning you will get a url of that API returning the live data in your database for you to inspect, right from the documentation page. Of course all of this is possible because you are self-hosting the Piwik on your server, but it is a good feature that I really liked.
