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!

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!
Nice work. But it can't detect Vue. 😕
V2.8.0 Not reliable, does not work. Didnt work on Facebook and on Google.
not working
This just stopped working one day. Until then it was great.
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
