Ember used to require jQuery but recently moved to removing it by default; users can opt-in if they still need it. Once the project moves to a later version of Ember I suspect the jQuery bit will drop off. (Who knows, though...)

Heavy stuff.

What extension is this?

Wappalyzer [1] is much better in my opinion.

And is available for both Chrome [2] and Firefox [3] as well as a Bookmarklet [4].

The extension that @pier25 is using seems to be available only on Google Chrome [5].

Wappalyzer's results for example.com, a 1.3 KB static page with no JS or sub-requests, include eight JS frameworks and two web font providers. Its results for facebook.com include a web framework made by Yahoo and deprecated in 2014. It says Youtube is built on WordPress, and HN is a React app with custom fonts.

I only see that HN runs on NGinx.

I was using the "Technology lookup" box on the homepage, testing with the extension I get only Nginx too. And Youtube seems right and example.com maybe right, though nothing at all for Facebook.

Similar tools include WhatRuns [1] (Chrome only).

Thanks, Wappalyzer looks pretty awesome.

UI Stack. Only for Chrome though.
