Manufacturer / project: Redgate

When does it fit?

Best for SQL Server teams needing fast, schema-aware synthetic data, foreign-key consistency, custom generators, command-line automation, and repeatable seeded runs. 1

Fit still depends on your mandatory requirements.

What should you check before choosing?

SQL Server scope; current requirements list Windows 10/11 and SSMS. Privacy masking, database subsetting, and virtualization are not documented. 1 · 2 · 3

What must your PoC prove?

Use a parent/child fixture, one invalid row and a fixed expected result. Check cleanup after failure, restore the configuration and repeat with pinned inputs. Unresolved requirements need a demonstration.
