Weavori

The product is a CLI tool that connects to PostgreSQL databases, introspects schemas, and generates synthetic data that preserves distributions, foreign keys, and cross-column rules for testing, staging, and development. It sells to developers and data professionals in b2b teams and startups that need realistic PostgreSQL test data without using production data. It is positioned against manual configuration files, generator definitions, and masking scripts by inferring column types, relationships, and distributions directly from the schema with zero configuration.
