Frameworks like RoR, Laravel, .NET framework provide most of it which are mostly SaaS in a box from technical perspective. Then you have headless CMS-es on top of which you also can build stuff. So you can plugin your email provider, payment provider, single sign on. It does not take much code but you still have to understand how to integrate stuff. Then you have wordpress where people basically install all kind of plugins and you can have all what was listed in CMS, but then you get "wordpress developers" to hire so I don't see much difference.
