Is there a program for convenient viewing of the site in different browsers?

Question

Web development

I wonder if there is a program dividing the screen into 4.6 parts like a table. And at the same time the site displayed in all parts at the same time. Approximately like this.

It makes no sense.
You don't have a 4K monitor.
And small pieces of the screen - not at all.
Now, as a rule, adaptive layout, so you need to consider it on a typical screen.
4 running browsers solve the problem perfectly.
