Greenmask
An open-source tool for PostgreSQL and MySQL database anonymization, synthetic data generation, and logical dumping.
What is Greenmask?
Greenmask is an open-source utility for logical database dumping, anonymization, and synthetic data generation, primarily for PostgreSQL with MySQL support in development. It solves the problem of securing sensitive data in staging, testing, and development environments by providing stateless, compatible backups that can be transformed or subsetted.
Database administrators, DevOps engineers, and developers who need to sanitize production data for non-production use while maintaining referential integrity and compatibility with standard tools.
Developers choose Greenmask for its deterministic transformations, storage-agnostic backups, and extensibility, offering a robust, drop-in replacement for `pg_dump`/`pg_restore` with advanced data masking and subsetting capabilities.
