Shameless plug: https://github.com/TreeTide/underhood https://github.com/TreeTide/underhood is a work in progress UI over Kythe indices (the same indices that power Code Search). If you already know how to index, this is a completely open source alternative, likely with less bells and whistles. I worked at Google and miss Code search. But I have lots of ideas as well how one can go beyond the status quo for code reading and debugging. Join if interested.
