What tech stacks do the worlds biggest apps use?

Do they publish their stacks or is it mostly a case of guesswork? Twitter facebook instagram snapchat tiktok google et all. Used to be well known Google used Python for their search engine but is that still the case with the scale it is at now? I wonder if they keep their stacks a secret as a competitve advantage?

Facebook was build from PHP, but they later created their a PHP transpiler HipHop for PHP which was later replaced by a virtual machine HHVM. This VM runs Hack which is suppose to be a dialect of PHP.
