Introducing Libscore.com

Every month, Libscore scans the the top million sites on the web to determine which third-party JavaScript libraries are installed on each site. Libscore aggregates this data to provide open source developers the numbers they need to measure their impact. Before Libscore, front-end developers only had Github star counts as a proxy for their library’s success. But most developers don’t star Github projects all, opting instead to bookmark Github pages or download libraries exclusively through npm or bower.
