Is there any Java/Kotlin library like https://developer.android.com/reference/androidx/recyclerview/widget/DiffUtil which can be used for Kotlin (non-Android) project?
I need it to find differences between two lists with custom comparator.

It looks like the source code for DiffUtil is pretty self-contained and it's Apache license. It's Java, but you could try copying-and-pasting it into a .kt file in IntelliJ Idea or Android Studio. The automatic Java-to-Kotlin conversion may give you something usable in pure kotlin.

Just doing a search on the internet brings up a few possibilities, such as https://github.com/andrewbailey/Difference. I haven't used any of them myself.

I use https://github.com/petertrr/kotlin-multiplatform-diff

[Matthew Feinberg]

@Robert Jaros Isn't that a text diff library? I think the OP is looking for a list difference that produces edit operations (add/delete/move) for animating updates to UI.

[Robert Jaros]

It does support diffing lists as well

Oh, very cool!
