About language coverage

I want to take tests some global website which has Chinese, Japanese, Korean and English version.

With Katalon, how many languages can I take a test without any problem?

We have one review from our user: http://www.hightest.nc/blog/posts/katalon-en-12-questions-reponses. They use Katalon Studio to test on French website and it still works properly, so to answer your question I can’t give the exact number of languages coverage, but I believe Katalon Studio can cover your mentioned languages.
