What is "libscore"

Libscore is a web-based tool that scans the one-million most popular websites to collect statistics on JavaScript library usage. It collects data on jQuery plugins, JavaScript variables produced by non-jQuery plugins, and JavaScript libraries loaded via RequireJS.

Libscore provides tools intended to help developers and technical analysts compare the relative popularity of web frameworks and third-party web tools.

Libscore was developed via a co-sponsorship by Stripe (a payments processor) and DigitalOcean (a hosting infrastructure provider).
