How is Katalon Trial different from Free Plans ?

The free license will apply to the personal emails, and the trial license will apply to the business email by default.

Valid email registration is eligible for a 30-day trial of both Katalon Studio Enterprise and Katalon Runtime Engine's floating licenses.

The free license granted for each Katalon account only includes the standard Katalon Studio with starter features. Currently, the free license for Katalon Runtime Engine is not available. If you wish to execute Katalon Studio in console mode, you need to subscribe to a Katalon Runtime Engine license. You can upgrade the free Katalon Studio to Katalon Studio Enterprise with a paid license without re-download.
