CourtListener

CourtListener is a free, open-access legal research platform operated by the Free Law Project, a nonprofit organization based in the United States. It is best known as a public alternative to commercial legal research services such as Westlaw and LexisNexis, giving lawyers, journalists, researchers, students, and the general public no-cost access to primary legal materials. The platform aggregates several distinct collections. Its core is a large corpus of judicial opinions from U.S. federal and state courts, which can be searched full-text and browsed by court, judge, and date. CourtListener also provides the RECAP Archive, a crowdsourced and automated collection of documents from PACER, the federal courts' electronic filing system, so that documents users pay for once can be freely accessed by others. In addition, the site hosts oral argument audio recordings, a database of judges and judicial appointments, and citation-lookup and citator tools that show how cases have been cited and treated by later decisions. CourtListener is closely associated with the open-law movement. Its data is exposed through a public REST API and bulk data downloads, and it is widely used by developers, academic researchers, and organizations building legal technology on top of open data. The Free Law Project has also used the platform to support related initiatives such as citation-network research and transparency around the federal judiciary. Because it is run by a nonprofit rather than a commercial publisher, CourtListener is funded through donations, grants, and membership support rather than subscription fees. It positions itself as a public-interest infrastructure project for the legal system, emphasizing free access, open data, and transparency. The service is active and continues to expand its opinion coverage, docket archive, and citator capabilities.

CourtListener was created as an open-source, free legal research project and later became a flagship initiative of the Free Law Project, a U.S. nonprofit founded to improve access to legal information through technology. The project grew out of the open-law and open-government data movement, which argued that court opinions and filings — produced at public expense — should be freely available rather than locked behind subscription databases. A defining step was the creation of the RECAP Archive. RECAP works as a browser extension and crowdsourcing system: when a user downloads a document from PACER, the federal courts' paid electronic records system, a copy is uploaded to the public archive so that the same document need not be purchased again by others. Over time this turned CourtListener into one of the largest free repositories of federal court filings. Beyond opinions and dockets, the platform expanded into oral argument audio, a structured database of judges and their appointments, and citation analysis tools that let users see how a case has been cited by later courts. The Free Law Project has also pursued research and advocacy around judicial transparency and the availability of court data. CourtListener exposes its data through a documented public API and bulk data files, which has made it a foundational data source for legal technology developers, academic researchers, and journalists. The service is sustained by donations, grants, and organizational support rather than subscriptions, and it continues to operate as a free public resource.
