“mabl when self-healing web journeys are the pain. Katalon when you refuse to give up script control across more than just browser flows.”

“Katalon covers web, mobile, API, and Windows desktop in one studio, and the free version let us start on our own machines. mabl's self-healing browser tests are nice, but we test more than the browser.”
