Data Maestro

0 reviews

Data Maestro generates realistic fake data for testing and staging environments, and anonymizes real PII in files or live databases — for teams that need realistic test data without exposing real customer information. 75+ field types across 5 locales with cross-field consistency (a generated name matches its generated email), 30+ export formats, and direct connectors for 14 databases (Postgres, MySQL, MongoDB, ClickHouse, and more) so generated data can be pushed straight into a real database. The anonymization pipeline scans real data for PII and masks/pseudonymizes it while preserving referential integrity across related tables — built for smaller teams and agencies that need this without an enterprise compliance budget. Native macOS app (SwiftUI + Rust core), local-first. Free tier available; paid plans start at $15/month or $349 one-time for a lifetime license.
