Open government data powers software applications that help people make informed decisions – from choosing financial aid options for college to finding the safest consumer products and vehicles. Below are just a few examples of government, community, and business tools that: use open government data from the United States; are accessible, vetted, and available; and are, for the majority, free and do not require registration to use. While we don’t endorse any particular app, we’re always interested in new examples: Submit application suggestions here.
