Hi,
katalon is new for me and i’m just starts to go through it. So as know that it is working for .Net Mvc project and if I want to create any keywords then what should I do.
Yes it will work without any problems.
Sorry but 1 thing I want to know that if this tool is free then how this organization earns…
Do you research how open source project earn money 
NO… I just ask u if I want some other keywords then I have to pay for that or not.
