Libscore – Collects Stats on JavaScript Library Usage

Libscore scans the top million sites on the web to collect stats on JavaScript library usage. In the search box, enter the case-sensitive variable that a library exposes itself as, e.g. jQuery, Modernizr, $.ui, or $.fn.fancybox.

Libscore aggregates this data to provide open source developers the numbers they need to measure their impact. Specifically, Libscore scans for third-party modules loaded with RequireJS, jQuery plugins, window variables produced by non-jQuery libraries, and cross-domain external scripts (e.g. analytics services and CDNs). It scans every site twice: once to pick up results for the desktop version of the site, and again to pick up results for the site’s mobile redirect page.
