Looks like Github used Angular.js. Would be interesting to hear how they settled on that. I've been using it for a side project and so far have had a positive experience.

Zepto I think. Can't tell if it's only the Zepto code but have a look on it here: https://gist.github.com/VictorBjelkholm/6003702

I don't see any sign of angular - what makes you think that they did?

Yes, definitely not angural.js. It would be still interesting to see their mobile webapp stack.

It's currently very simple.

The mobile app is just part of our main web app. We use the same models and controllers as our desktop views. We have separate markup, different bundles for mobile JavaScript and CSS, and separate view models[1].

Pretty sure they use PJAX.

I don't think they are. It's really minimalistic. Just Zepto & a small bit of scripting for the navbar.
