PostgreSQL Anonymizer vs Tonic Fabricate

PostgreSQL Anonymizer is an extension for masking or replacing personally identifiable and commercially sensitive data in PostgreSQL databases. Masking rules can be written in SQL with PostgreSQL DDL and kept in the database schema. Its documented approaches include anonymous dumps, static and dynamic masking, replica masking, masking views, and data wrappers. Functions can randomize, fake, partially scramble, shuffle, add noise, generalize, or apply custom transformations. A masked role can export anonymized data through pg_dump; masking rules should then be removed from the dump. Identifier detection searches common names in English and French, but may flag non-identifiers or miss identifiers. Installation instructions cover Linux and self-hosted PostgreSQL. The extension can be built from source on macOS, without community support there; Windows use is described through PostgreSQL on WSL2, as there is no native build. Installation requires superuser privileges, so a cloud database provider must offer the extension in its catalog. The plan is free. Commercial support is available separately.

Tonic Fabricate uses a conversational AI agent to create synthetic data for databases, APIs, and files. It targets product development, software testing, AI model training, reinforcement learning environments, and sales demos. Generated content can include relational records, JSON, PDFs, DOCX files, and emails, with domain details and relationships preserved. An optional Validation Agent reviews output and prompts refinements. Fabricate can create mock APIs from uploaded specifications and define workflows callable through an API; its MCP supports generation from compatible clients such as Claude and Cursor. Listed connections and formats include PostgreSQL, MySQL, Oracle, Databricks, Snowflake, SQL Server, MongoDB, Amazon S3, Avro, Iceberg, and Parquet. Free costs nothing and lists $5 in monthly credits; Plus costs $29 a month with $25 in credits. Enterprise has custom pricing and offers Tonic Cloud or self-hosting. Tonic says synthetic records can reduce exposure to real sensitive data and support GDPR and HIPAA compliance.
