Overview
Product summary
Review the store description, core capabilities, and common use cases.
The Library Detector extension discovers which Javascript libraries are being utilized on webpages you visit and displays their icons, along with a link to the library's homepage, in the address bar.
Figure out which cool libraries are powering today's websites. You'll be surprised to learn about some of the more esoteric libraries that are out there. You'll also be horrified by the awful cocktail of libraries that some popular sites utilize!
Supports over 80 Javascript libraries, and growing with every version. Visit the support link and file a request if you think anything is missing. Or, better yet, fork the project on Github!

Keep it going! I like the idea. Add more library detection.
Not detect SPA pages (on angular on similar)
Very useful
Great extension, quite helpful for JS developers.
Nice, but seems to display an unclickable 'space/blank' icon when visiting google drive and gmail pages.
Why did it take so long for someone to make this? It is great for knowing how a page has been put together at a glance.
