In their own words
Data Maestro
Data Maestro is a local Mac app for generating synthetic data, anonymizing personally identifiable information, seeding databases, and serving a mock REST API. Its generator provides more than 75 field types across five locales, with consistent related values, repeatable seeded output, and streaming or parallel processing for millions of rows. A scanner detects emails, phone numbers, SSNs, credit cards, and IP addresses; masking can preserve formats and relationships across live database tables. Connectors span relational, document, and other databases, while imports include common file types, schemas, and API specifications. More than 30 export formats are listed, including SQL dialects, Parquet, Avro, BSON, and OpenAI fine-tuning JSONL. The mock server can return JSON, XML, or CSV and supports pagination, custom headers, CORS, and OpenAPI import. The maker says processing happens locally and saved connections, templates, and datasets are encrypted at rest; license activation and update checks make network calls. The native app requires macOS 14 or later on Apple Silicon. After the 30-day full trial, the free tier limits exports or database pushes to 100 rows and saved connections to two.
DTM Data Generator
DTM Data Generator creates database rows and schema objects for test population, performance analysis, quality assurance, and load testing. It examines existing schemas and resolves master-detail key relationships, then fills fields through fifteen generation methods, about 70 built-in functions, and an expression processor. Values can come from databases, CSV or text files, Excel, XML, JSON, web resources, and user-defined scripts. Connections use ODBC, OLE DB, or Oracle Call Interface; JDBC is available through the multiplatform runtime. Named systems include SQL Server, Oracle, IBM DB2, Sybase, Informix, MySQL, PostgreSQL, Interbase/Firebird, and SQLite. Results can load directly into databases or become SQL, text/CSV, XML, or JSON. XML and JSON output require Professional or Enterprise, while scrambling requires Enterprise. Standard permits 128 rules and 10,000,000 rows per rule; higher editions allow unlimited rules and higher limits. It runs self-hosted on Linux, macOS, and Windows.
