Third party product to sync ADDS GPOs between domains?

A few years ago (about 6?) I ran into a product that would centrally store GPOs and allow you to build out labs, testing, and POC GPOs to deploy from. You could sync changes from the repo out to any linked in/authorized domain, so you can keep GPOs in sync between them. Anyone know what the hell that product was called? Its not the MODP tooling tied to SA, it was a third party.

I know we can manually sync GPOs using MMC, but this is cumbersome and some of my engineers are missing changes from testing to the third and second domain due to laziness. Lack of logging limits my ability to correct from a personnel level. I don't really want to have to manage all of the GPOs myself...so...
