Anonyx is a self-serve SaaS that anonymizes production databases so teams can use realistic, GDPR-compliant data in non-production environments (dev, test, CI/CD).

Unlike naive masking scripts and most free tools, Anonyx anonymizes in place while preserving referential integrity, foreign keys and cross-table consistency stay intact, so the resulting database is immediately usable. No application code changes required.

Features: automatic PII detection, a full REST API with webhooks and scheduled runs to wire anonymization into your CI/CD pipelines, and multi-engine support for PostgreSQL, MySQL, MariaDB and SQL Server.

Anonyx is EU-hosted and offers a free tier, with no sales call required to get started. It's the practical alternative to enterprise, sales-led platforms (Tonic.ai, Gretel.ai, Mostly AI) for engineering teams that want production-grade anonymization without the friction.
