Webdriverio
In gemini, you can test in many browsers at once. I don't know much about the webdriver.

Answer 2

An interesting task, but Selenium is not a test framework, but just an API for working with browsers using web drivers for each browser.
Accordingly, if there is a need to use Selenium, then you will have to use libraries for working and comparing pictures and connect them to the test project and use them.
