Is there a more or less adequate online system for checking the display of a site in different browsers?

Question

css

Comrades! Maybe someone came across the issue of checking the display of a website in different browsers and on different operating systems. I googled a lot on this topic. There are such systems. But they don't do their job very well. Please share your knowledge on this topic. What online services should you look into?
PS
It is desirable that the service had the possibility of something like batch processing. For example, you set a URL, and in response you get a series of screenshots in different systems and browsers.

Answer 1

browserstack.com/

Answer 2

The first and hardcore - virtual machines, pre-installed browsers and parallelized tests chasing your machines.
The main disadvantage is that it is necessary to maintain a zoo of these same virtual machines, although given that the list of browsers and supported versions is relatively static, this is not a particularly big problem. But at the stage of creating this very zoo, you will have to suffer.
The second option is tools designed for this. The already mentioned BrowserStack, SauceLabs (which I personally recommend) and a bunch of alternatives that can be found at alternativeto.net/software/sauce-labs
drives emulators instead of specific browser versions). + problems with local hosts and other things.
So it goes.
