Is there any Limitation of No of Execution Profiles Created inside a Project

[kazurayam]

I think that it is not feasible of creating 500 Execution Profiles as Katalon Studio GUI would not be able to render them graphically. Simply, 500 exceeds the design assumption; any problems may occur; nobody can predict what will happen.

I would propose to you an alternative:

Configuring a Katalon Studio project with a JSON file

I have published a GitHub repository Problem to solve Katalon Studio provides Execution Profile and Global Variables. Execution Profile helps cover multiple and different environments to execute your automation test scripts with ease. You can configure the testing environment in terms of data and behaviors through Global variables. You can update the value of GlobalVariable during test runs but you can not persist the updates into Execution Profiles. If you want to change the persisted v…

You would need to create only 1 or 2 Execution Profile, and 500 JSON files. Your code will load the JSON file and transfer the data into the GlobalVariables. This way is certainly feasible. Katalon Studio GUI would not stop you doing this.
