Katalon Studio vs Mailinator: Which is best for you?

The only thing that I can think of is that it would be nice if Katalon Studio had more built-in functionality for things like creating and managing tests cases, etc. But, even without that, Katalon Studio is still a very powerful and comprehensive automation tool.

Lack of support for Linux

Great experience, fits the need to have email test accounts. And with MFA support, you can have end to end testing with hardened login services (e.g. Azure SSO)

The inability to scroll through pages quickly, have to go one by one through the next button which requires a wait for the current page to load.
