• Preserves referential integrity and statistical distribution, so applications behave as they do in production.
• Directly addresses the GDPR and HIPAA exposure created by production data in lower environments.
• Subsetting produces a small but coherent slice rather than a full copy.

• Realistic, locale-aware data catches layout bugs that 'test test test' never will.
• Seedable, so generated data is reproducible when a test fails.
• Available in every major language with a similar API.

• Expensive, with enterprise-only pricing.
• Initial configuration of sensitive-field classification takes real effort.
• Adds a pipeline stage that must be maintained as the schema evolves.

• Generated data has no referential integrity or business rules — that is your job.
• Random data makes failures harder to reproduce unless you seed deliberately.
• Not a substitute for production-shaped data at realistic volume.

Organisations that currently copy production data into staging and know they should stop.

Every project that needs fixtures more realistic than placeholder strings.
