Is Selenium Headless the Best Way to Run Automated Tests Without a GUI? or How Reliable is Selenium H

10-15% speedup is actually decent if you’re running at scale. Multiply that across 1000 tests, and it adds up.

For captchas, you might need proxies or a service like 2captcha. Pain in the butt, but whatcha gonna do?
