FederalRegister.gov is Open Source

Project Source Code

FederalRegister.gov is a fully open source project and its source code is available on Github.

The FederalRegister.gov source code is available in two repositories. The first, federalregister-api-core, contains the code that powers the import of Federal Register data from various sources and serves our API responses. This repo is undergoing active cleanup as we break the FederalRegister.gov code base into smaller pieces.

The second, federalregister-web, contains the code that displays the FederalRegister.gov website. Its primary data source is the FederalRegister.gov API.

Additionally we are in the process of moving the FederalRegister.gov server architecture from Chef to a Docker based infrastructure. We will make these available on Github once they are ready.

We welcome your contributions and feedback.
