Expanding beyond the U.S.

How we work
A few things we believe in.
Public data should be public
Government databases are funded by taxpayers and belong to everyone. We make them navigable.
Free means free
No account required. No paywalls. No freemium tiers. Everything we ship is free to use.
You are not the product
No ads. No tracking. No data sold. We keep the lights on through voluntary tips from people who find the tools useful.
Small team, careful work
We move deliberately, ship when things are right, and stand behind what we build.
