I find Sourcegraph really interesting as a different approach to code indexing. Opengrok, Krugle, BitBucket Server and my own poor attempt searchcode and the downloadable server version simply index the source code as is which is to just index everything thats text (with some smarts on top usually). By comparison Sourchgraph builds parse trees and attempts to understand it. I am not sure as to which approach is better for the average user, but I do think that if you are using a language currently supported you should give it a try and compare to one of the afore mentioned solutions.
