Libscore
Libscore is a web-based tool that scans the top million sites 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.[1]
Libscore is the sole free provider of in-depth JavaScript library usage among the Internet's highest traffic sites. This data helps developers and technical analysts to compare the relative popularity of web frameworks and third-party web tools. In addition, the ability to retrieve the libraries in use on a given site provides operating insight into the web development architecture of major corporations.[2]
Behavior
Libscore scans the top million sites on the web to determine which third-party JavaScript libraries are installed on each site. Developers can use this data to determine which libraries are trending in popularity, which libraries are in use on popular sites, and how libraries' market penetrations compare. This data helps developers perform competitive analysis and make informed decisions when choosing libraries to work with.[3]
For each site Libscore scans, it runs heuristics to determine which window variables are produced by third-party JavaScript libraries. In addition, it catalogues the presence of external JavaScript scripts. Thereafter, via the Libscore homepage, users can search through the aggregated data in order to:
- Find the prevalence of a specific JavaScript variable
- Search for sites containing a specific external script
- Find out which JavaScript libraries are being used on a specific site
Libscore also provides monthly statistics on the top libraries, scripts, and sites, in addition to regularly publishing charts showcasing library adoption percentages.
There is also a Libscore API that provides developers programmatic access to Libscore's monthly data.
History
The project was jointly created by Stripe and DigitalOcean in 2014.[4]
