There are a few companies selling all of that in a single package as a SaaS boilerplate application: If you like PHP - https://spark.laravel.com/ https://spark.laravel.com/ If you like Ruby on Rails - https://bullettrain.co/ https://bullettrain.co/, https://www.getsjabloon.com/ https://www.getsjabloon.com/, https://railskits.com/ https://railskits.com/ If you like NodeJS - https://usegravity.app/ https://usegravity.app/ If you like ASP.NET - https://aspnetzero.com/ https://aspnetzero.com/ If you like Python/Django - https://djaodjin.com/ https://djaodjin.com/ I can't specifically recommend any of them, as I never used, but I used another one built with Rails+EmberJS that was worth the money (I am not sure if it's still supported these days, but here it is https://www.maxiomapps.com/apps/application-starter-kit/ https://www.maxiomapps.com/apps/application-starter-kit/). If you want to build a SaaS web app for problems that don't require cutting edge technology to be solved (aka most of them), I think buying one of those is a no-brainer in terms of cost/benefit.
