The entire JVM ecosystem is built around "we all know you're using an IDE, right?" I among most folks who use Kotlin are aware of the Community Edition of IntelliJ. The price isn't the thing keeping me from using it. 1. an employer _should_ be covering that cost. 2. The tools is truly outstanding and well worth the 500 bucks (I'd argue it's not worth 500 bucks a year but...) With all of that said, I really don't enjoy the IDE experience. I do tend to write Kotlin + Quarkus in NeoVim... but the LSP is a volunteer effort. Meanwhile Rust and Go's LSPs are incredibly.

My biggest complaint against the JVM community will alwyas be, "don't expect that we can auto-import... document where methods/constant/imported vars come from".
