The backstory
Mockaroo let you pick field types from a long list and download thousands of plausible fake rows for testing and demos. Its catalogue of generators, names, addresses and product categories was the product. A model handed a schema now writes seed data that is coherent across columns, matches your domain and comes as an insert script or a factory function. Free tiers and per-row limits look strange when the alternative costs one prompt.
