What our customers are saying

“SQL Data Generator is almost magical when you see it in action over your own data schema”

Troy Hunt,
Software Architect

“Redgate's SQL Data Generator inserts 500K rows in the same time that Visual Studio Team System does 300 - not 300K, just 300.”

Barry Gervin,
ObjectSharp Consulting

“SQL Data Generator is simple and effective. It used to take me hours to generate useful test data, for example so we could show our web product to clients. With SQL Data Generator I generated better data in only half an hour, and then, after this initial customisation was done, in only seconds, with just one click.”

Michael Gaertner,
Quintech

“In less than the time it took me to get my coffee, I had a database with 2 million rows of data for each of 10 tables. The database was filled with proper names, cities, geographical locations, FK links and I was able to use the Regex Generator to finely tune specific columns data.”

QA Manager,
