Code search, critique, Piper/citc/cider are amazing for developing

Power drill is fantastic for drilling down data. So much money was made thanks to this one.

Piper was actually a big source of frustration for me. Yeah it's dead simple, but once you have a CL chain, you're entering a world of pain. I've switched to Fig a while ago and haven't looked back. Beyond a tiny fix I'll start editing from CS or a throwaway citc client, it's just simpler to use fig. I've been able to juggle 4-5 CL chains easily and it makes my workflow much easier. Also splitting CLs before review is much simpler with Fig.

Are these code tools built using https://github.com/kythe/kythe ? Any other OSS projects by Google that back these?

I believe so. Kythe seems to have spawned out of the internal CodeSearch.

Something that is not by Google but which you would probably like - SourceGraph. Has commercial options but it is OSS.

Do you have a list of all major Google tools and why they're better than what's available elsewhere? (if so)

In my opinion, what makes them really great is the tight integration that they have. For example, since the whole company uses one build system and one single repository, you can build a truly awesome IDE that knows about every library in the company and can autocomplete for it. Same for code search, where cross references are accurate and work cross languages (for example a class generated from Protobuf).

Outside Google, the percentage of my coding time I spend hunting some dependencies source tree for the relevant header files or documentation or "Where on earth is this constant defined" is huge.

With codesearch, answering those kind of questions is near instant.

So CodeSearch, Critique, Borg, Sherlog, Cider come to mind as top notch tools that are not available outside. As far as libraries go, the C++ Fibers thing is incredible and I don't think it's open.

Blaze is amazing (albeit a bit slow) but Bazel should be more or less the same, haven't used it. Dremel, Spanner, Tensorflow, Proto, grpc are all available outside. Abseil (https://abseil.io/) is a great library available to everyone.
