Setting up open source Anvil is kind of easy and I already have multiple virtual servers, actually I’m running my DB on one of those and uplink db connection works seamlessly with Anvil. So I can work in Anvil for development and use a virtual server with open source Anvil as production server.
I think I’ve got more than enough answers and options, with useful links and details. Thank you for everyone to help me to understand alternatives for LTS.
