Datamimic – don't let your coding agent invent its own test world

Datamimic is an open-source, Python-based tool for generating synthetic test data and performing PII-aware pseudonymization in regulated enterprises, available as a Community Edition under MIT license. The tool enables deterministic data generation without requiring source data and supports multiple database formats and file types, while an Enterprise Platform version adds governance features like audit logging and role-based access for production-scale operations. AI agents can use the project's CLI to scaffold data models and repair configurations through structured workflows.
