I think you might be looking for Firebase, it is basically a set of components that you can use on your web application and you'll find things like database, authentication, payments, caching.
You could also look at Vercel and Heroku, I think they do similar things, but I've not used them a lot.
Django + Heroku is a good stack for full (batteries-included) web apps.
Nextjs has a stripe integration template with supabase, easy for quick iterations and prototyping.
Thank you all for the recommendations.
Supabase
I would recommend Ruby on Rails - you will find well establish gems for everything you need (eg: devise for auth, pay gem for paymens, sitepress for static content like marketing pages …)
There are also some very well done (simple to understand and maintain) starter kits. Here are two of them:
- https://jumpstartrails.com
- https://businessclasskit.com
I would recommend Avo (and I am doing so for a couple of projects) as a super great admin to manage everything:
