Built by a Developer, for Developers
AlfaAlfa Software Corporation was founded in 1999 by Dariusz Dziewialtowski-Gintowt, a software developer based in Toronto, Canada. The company was born out of a simple frustration: there was no easy, affordable way to quickly find the differences between two SQL Server databases.
SQL Server Comparison Tool (SCT) was created to solve that problem — and it has been solving it ever since. Over the past 25+ years, SCT has grown from a small utility into a trusted tool used by hundreds of organizations worldwide, from independent developers to some of the world's largest corporations.
Our philosophy has never changed: build focused, reliable software that works exactly as advertised, price it fairly, and stand behind it with real support. When you contact us, you're talking to the person who actually built the software.
