Question automated test tools for functional testers

Good day all,

For my company I am making a list for the functional testers.
What will be on the list?
Automated test tools that the functional testers (without programming knowledge) can use to make automated tests. They know how to use BDD.

So my question to you is: do you know any of these tools?
I already have: katalon (but that is payed when the customer wants more), Selenium IDE and Behat.

Hope that we can get a huger list.
The best option is open source so that they can use it for free and also the customer doesn’t have costs.

Myself I am a functional tester that can program. So i write my automated tests myself via selenium webdriver.
