I can relate to your experience. Recently, I was looking into various platforms that provide cross browser testing facility through cloud. The competition is intense! However, every tool has almost the same pricing plans for their services, except one! You should check out LambdaTest, it is a free cross browser testing tool providing 2000+ browsers and browser versions as of now. They also have a flexible on-demand pass for freelancers where you could get unlimited access to their platform in just $15 for 10 days.
This has been a great deal to me from time to time.
