| Assessment | CourtListener | PACER |
|---|---|---|
| Reading the vendor's wording | The service is built on public court records and states that it is sponsored by the non-profit Free Law Project. Because the underlying material is public, the confidentiality question is different from a commercial platform holding firm work product. The checked pages do not publish a data-handling statement. | The service provides access to public federal court records. The confidentiality question that applies to a commercial platform holding firm work product does not apply in the same way, because the material is already public. The checked pages do not publish a data-handling statement. |
| What adopting it costs | The switching cost is very low, because there is no subscription and the data is public. The relevant cost is any integration built against the API. | There is no switching cost in the usual sense, because there is no subscription. The relevant cost is any workflow a firm has built around third-party tools layered on the same records. |
| Closest alternative | Fastcase — The closest alternative. Both offer broad U.S. case-law access; Fastcase is a commercial library now inside the vLex and Clio group, while this one is free and non-profit. | CourtListener — The closest alternative for access to federal records. CourtListener is free and non-profit, but it is a third-party copy rather than the judiciary's own service. |
