The team behind Real Fake Data

Real Fake Data started from a recurring frustration: faker libraries produce data that fails the very validators it is meant to test against. National IDs with wrong checksums, addresses that match no real geography, tax numbers that no system would accept. We wanted test data that behaves like production data — without ever touching a real person.

Today Real Fake Data is a focused API for synthetic-but-valid records: national IDs and tax numbers with correct checksums, addresses built from real cities and streets, and deterministic seeds so your fixtures stay reproducible. It is a commercial product, built and maintained by a small team that uses it every day.
