Library Detector Extension

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!

Al Murray (ID: 000000415a6e9682) Voted 4 ★ - Updated 10/18/2023 It was good when it worked but I can't get the popup to show anymore. Will try on a fresh Chrome install and see if that helps.

Ishank Dubey (ID: 000000dd4f0afc56) Voted 5 ★ - Updated 09/22/2021 I like this plugin very much, I am a seasoned dev and this plugin helps me to quickly figure what JS framework(s) a site is using, yes sometimes it doesn't work but I think thats still ok!
