GovWayback is an independent tool that helps people access archived versions of U.S. government websites through the Internet Archive’s Wayback Machine. Users can add “wayback.com” after “.gov” in a supported web address to be redirected to an archived version of that page, generally from before January 20, 2025. The service supports a range of federal agency, congressional, and other government domains, including sites for the CDC, EPA, Congress, NASA, and the National Park Service.

GovWayback does not create or store website archives; it provides a convenient route to material preserved by the Internet Archive. Because a requested page may not be archived or available through the redirect, the project advises users to check the Wayback Machine directly for other capture dates. For citations, it recommends using the Internet Archive’s direct archived URLs. GovWayback is not an official government service and is not affiliated with the Internet Archive or its Wayback Machine. It encourages users who value this preservation work to consider donating to the Internet Archive.
