When you come across a nicely built website, don’t you always wonder what technologies the site is built with. Perhaps a sneak peek at the page source can give you some idea.
But there’s an easier method. There’s this nifty little Chrome extension called BuiltWith (available for Firefox as well). When you’re in a webpage simply click the BuiltWith icon and it pops up with the list of technologies the page is built with and a small description of each of them. The image shows a part of the list twitter.com is built with. Yes, it works on https sites as well.
This may not be much of a thing for some people, but if you’re a noob about these things like me you’ll be able to learn a lot of web-tech stuff with this.
