Should firebase be used for large projects?

Question

JavaScript

Hello everyone, I started to write an admin panel on firebase and use storage and all the features of cloud functions
In terms of budget, is it worth creating a site similar to cian.ru on firebase?
I can’t calculate how much the site will cost me, which will be visited by about 500k people a day.
What do you advise?

Answer 1

Can't calculate

Because it is a bit problematic to calculate the load on the server with not yet written code with 500k visitors not yet received .
