A Civic Tech DC initiative

Open-source tools for a more transparent Congress

Congressional Tech is a volunteer effort, in partnership with the American Governance Institute, to make legislative information easier to find, track, and understand. Every proposal here answers a real-world request from people working in and around Congress — nineteen of them across five themes, with working tools already shipping.

Two proposals are working tools today, with more in progress across the five themes.

DeltaTrack and BillTrax are Congressional Tech sub-projects with their own repositories, kept in sync with their upstreams daily. Both advance the appropriations data pipeline proposal, I.4.

Sub-project · Live

DeltaTrack

DeltaTrack structurally diffs two versions of a U.S. bill and shows what actually changed — added, removed, modified, and moved sections — instead of the formatting noise a plain text diff produces.

BillTrax

BillTrax is a public-facing legislative-intelligence platform that turns raw congressional data into structured, searchable, and summarized bill information for researchers, advocates, and planning teams.
