Greenmask is an open-source CLI utility for logical database dumping, anonymization, synthetic data generation, and restoration, production-ready for PostgreSQL with MySQL support in beta. It is stateless, requires no schema changes, and produces dumps compatible with standard tools like pg_restore and mysqldump.

Use cases

• anonymize production data before sharing with developers
• generate synthetic test data that looks like production
• create smaller referentially intact dev database subsets
• mask PII in database dumps for staging environments
• dump PostgreSQL database to S3 with transformations applied
• keep masked data consistent across dumps with deterministic transformations
• integrate database anonymization into CI/CD pipelines

When to choose

• you need to anonymize or mask PostgreSQL data in logical dumps without changing the schema
• you want deterministic, reproducible masking with referential integrity and constraint awareness
• you need database subsetting or S3-compatible backup storage
• you want a stateless tool compatible with pg_restore

When to avoid

• you need MySQL anonymization in production (still beta)
• you need anonymization for databases other than PostgreSQL and MySQL
• you want a GUI-driven data masking platform
• you need real-time or in-database masking rather than dump-based
