Second paragraph my eyes landed on when opening the link: "Create secure optimized connections with a few lines of code. Between servers or services running on any cloud or machine."

Sounds like an VPN to be used on servers for connection between services. Feels like a pretty easy to understand explanation of what it is.

Actually pretty neat to have tunnel configurations in code, not that you can't have that without syntropy, but it's a neat little feature.
