Library Detector
Description from store

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!

Really useful for JS library detection, specially concerning JS security issues on multiplatform systems

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.

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!

Pretty good except it doesn't detect certain framework properly. e.g., it shows "React null" on a bunch of websites, regardless of whether they are using React or not.

Unfortunately the extension does not detect important frameworks like React.

Excelente, sencillamente está bueno para saber que tecnología usa una página de un cliente o un proveedor. Sólo falta que se de cuenta de reactjs. Pero react tiene su propio plugin, así que estamos cubiertos. gracias.

Fun to see what libraries are being used!

I agree with Chirag. Its nice, but there are some major libraries that are missing. Another missing library is React

me gusta mucho, es muy útil ademas de que al detectar una librería me lleve a su sitio oficial

Keep it going! I like the idea. Add more library detection.

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.
