I know about the open source version, but it basically go against why to pick Anvil. If I have to deal with the server side from install to security update, I would stick to .Net core or other already known (by me) solutions.
I can see how good is Anvil to prototyping, but I don’t want to porting or refactor anything because it goes to production later.
Using the current server just not giving me the stability I’m looking for.
I have servers running already, so it is not about how to set up, but which solution would make more sense. Using .Net Core gives me more flexibility and in case of using the open source Anvil, it is kind of the same complexity to set it up and maintain. On the other hand, Anvil with python gives such a clean code that I cannot close my eyes on that part. Using the open source Anvil, I would lost the UI editor as well… so many yes and no in my case 
Anyway, thanks for the answers!
