I need a Version Control System

Hey there!

Does anyone knows about a working WordPress VCS on the market? Something like VersionPress. I contacted them before but they terminated their service. I also know GeekBee.io which seems to be great but they are still searching for their testers since they are not finished the product.

What is important: possibility to make staging environments, merging databases after the changes, easy to use, and of course it is important to be tried and reliable.

Thanks in advance!
