Small tools, built properly

Test data without the risk

Generate realistic datasets, anonymize production databases, and mock APIs — in one native app that keeps everything on your Mac.

  • Data Generator — realistic names, emails, and records across multiple locales, exported to files or straight into your database.
  • PII Anonymizer — scrub real customer data before it leaves production, with audit trails.
  • Fake API & schema import — mock endpoints and reuse existing schemas, no backend required.
