Hello, any recommendation for tool that it is easy to integrate with for performance testing. for example gatling but it is written in scala and SBT and thus hard to adopt for Kotlin developers/ Java using gradle only. (trying to avoid magic tricks)

not kotlin specific but vegeta is pretty easy to deal with. https://github.com/tsenart/vegeta Written in go and all you need is a file with a list of urls and you can run it against some endpoint. Also comes with some options for producing graphs.

good to know, i will try too

will have a look thanks
