A powerful, feature-rich, random test data generator
...Earlier versions were written in PHP and MYSQL and 3.x offered a REST API to let you generate the data programmatically rather than via an API. While this is still planned for 4.x it's not currently offered, and the plan it to tackle that after making the script available as an npm package - which we feel will be a more convenient way to programmatically generate data over the more agnostic REST approach.
