someone should make a GUI and a subscription service for that. Oh wait, you just invented the current state of the web :/
The often maligned “setup wizard” UI a lot of us remember from not so long ago actually was kinda neat in many ways.
Run “I want a website app” and click through a few simple menus that ask you questions to get you set up with a domain, email, hosting, etc. The defaults would be a selection of ideally smaller/non-FAANG providers, with some power-user menu or some shit gated behind a checkbox.
Then it just saves a document with your new CMS/etc logins, and away you go.
I guess you could even make a few bucks off it by using referral codes or whatever to fund development cost.
