Mission: To increase the transparency of and foster more openness and accountability in government.

Through its (WIP), which was launched in 2018, the foundation seeks to hold the federal government accountable for changes in the information it makes available to the public, as well as changes in its stated policies and policy priorities. With the help of watchdog organizations such as the and the , the news media, and WIP team members, Gov404, the project's censorship tracker, aggregates and verifies instances of the most significant online information censorship on the federal Web since November 2016. To that end, the tracker highlights changes to and removals of website resources and materials resulting in a substantial reduction in access to content that is of interest to users of those sites and/or that reflects changes in agency policy.
