Appeon

Appeon's PowerServer is part of its PowerBuilder CloudPro offering. It automatically deploys a client/server PowerBuilder application as an installable cloud application backed by REST APIs running on .NET Core, while retaining the PowerBuilder development model.

That makes it relevant when the goal is to move a PowerBuilder application to a cloud deployment model without a ground-up rewrite. It is not the same as converting a PowerBuilder codebase into a standalone C# application, so teams seeking that endpoint should verify the target architecture and conversion scope.
