Coyote Badger is an application that automatically pulls legal sources from article citations. It’s used by law journals (such as Texas Law Review and California Law Review) to quickly collect original source documentation that can be used to validate citations when reviewing legal articles for publication.

It can pull a variety of citation types like state statutes, federal statutes, SCOTUS cases, non-SCOTUS cases, journals, and articles across Westlaw, HeinOnline, SSRN, and other websites. Under the hood it uses:

• Playwright to automate the browser
• Xfce to stream a live view of the scraper
• Flask as the backend for handling requests in the application
• Docker to seamlessly deploy across users’ varying setups

The application has pulled 6,000+ sources and saved Texas Law Review more than 275 hours per year.
