in reply to Perl equivalent of Watir

the CPAN module for Playwright is created and maintained by the same CPAN author (TEODESIAN) that has maintained the Selenium driver for years; he vastly prefers Playwright these days. Firefox::Marionette is also a browser specific module that talks directly to .. you guessed it :-). I've had great success using it with Web::Scraper when needing to access javascript rendered pages.

Playwright more or less generalizes talking to browser via the "wire protocol" each of them maintain. Note: the Perl module uses the standard nodejs based daemon as the middle ware, but gives it a nice Perl interface and other goodies. Another thing to note is that Playwrite is from Microsoft and is generally considered very well done with lots of great docs.
