Are large projects being done on frameworks? And on what are they generally made?

Question

Computer networks

I wondered what large sites are made on. I'm not talking now about social networks, it's clear that they have their own. For example price.ru or similar highly visited sites. And is it even possible to do such projects on frameworks?

Answer 1

Yes, they are made on frameworks.

Answer 2

On the site of any framework, it is usually written in the about section what large projects are written on it.

Answer 3

instagram is made with Django, many sites use SQLalchemy - python ORM
