  • Track your correspondence in a transparent public forum, then share it with your community over social media.
  • OpenCongress is different because all our data (except for personal info) is fully open for a more accountable government.

OpenCongress is a free, libre, and open-source project. If you believe in open government, please support our work with a tax-exempt donation. We're a tiny team building big (not-for-profit) things, and we need your help.

Charitable foundations, political bloggers, issue-based groups -- this is just the start of what we can build for government transparency & accountability. With additional funding, we can develop more amazing open-source tools for fighting corruption and deliberative democracy. Check out our non-profit funding prospectus at left for more info.
