| Fact | Mockaroo | Synthetic Data Vault |
|---|---|---|

Pick Mockaroo if…
Mockaroo suits developers and testers who need realistic sample records or mock APIs. Front-end developers can use it while a back end is not yet ready.
Pick Synthetic Data Vault if…
SDV may suit data practitioners who need synthetic single-table, sequential or relational data and want tools for evaluation and customization. The on-premises Community SDK and listed database connectors may also interest teams working with those environments.
