A cursory glance shows Apache. Akamai for their CDN. Sentry for tracking. Years ago Apple used to use Script.aculo.us and Prototype, but of course that was ages ago. They seem to have an internal CSS framework they use, as well as custom JavaScript per-page, in-house iconography, and a many-years-old page architecture with component names like the globalnav and globalfooter. They have an internal package org called "marcom" which is short for Apple Marketing Communications.

Over the years, I've watched their front-end change but for the most part, their page architecture has stayed the same. It's actually really nice from the point of view that they got something right, and didn't screw around with it every single year like how most front end web developers seem to do for the sake of doing it.

Their web pages, along with some of the other high class work on say, Awwwards, are a masterclass example of learning from top talent.
