The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Java 21 makes me like Java again
Yeah, it has nice funcional capabilities and libraries (like Arrow[0]).

Is it prudent to use Scala for anything new?
Last but not least, Scala is currently the language with one of the best effect systems in my opinion (https://zio.dev/). Kotlin for example has copied the approach with https://arrow-kt.io/ which I think is great actually. But when comparing Scala and Kotlin here, Scala wins by a large margin, it is a completely different world. It's like building a highly concurrent system in Erlang vs C.
Of course, if you don't want to learn things like union types, traits/typeclasses and effects (similar to async/await but more powerful) you will be annoyed by Scala. But once you learned them, you can never go back.

Struggling with software robustness with Kotlin
In my own code, I started to use explicit error handling. I'm currently experimenting with Result (from https://github.com/michaelbull/kotlin-result) and Raise (from https://arrow-kt.io/).

Hey Rustaceans! Got a question? Ask here (5/2023)!
Are there any more-or-less established functional crates in Rust (similar to Kotlin’s Arrow)?

What's the benefit of using Arrow with Kotlin?
I wonder how the community sees adding Arrow besides standard Kotlin language features. Is it something that's still considered useful or just redundant and causing more confusion?

ArrowKt/FP - Tracking paths to validation errors
You can define a function like context(EitherEffect) suspend fun MyType.bind(path: String)like the ones in https://github.com/arrow-kt/arrow/blob/b608a054a5318fe57d7055c35bb64a5effb053b6/arrow-libs/core/arrow-core/src/commonMain/kotlin/arrow/core/computations/either.kt

Dart Functional Programming
If you're using Kotlin, I'd highly recommend looking into the https://arrow-kt.io library. It's quite a bit more sophisticated than the Dart FP libs, and meshes well with Kotlin. They've got a great website, but even better is their engagement on the #arrow channel on the kotlinlang.slack.com Slack.
What are some alternatives?
When comparing Result and Kategory you can also consider the following projects:
RxKotlin - RxJava bindings for Kotlin
cats-effect - The pure asynchronous runtime for Scala
kotlin-result - A multiplatform Result monad for modelling success or failure operations.
Snail-Kotlin - An observables framework for Kotlin
kotlin-monads - Monads for Kotlin
Reduks - A "batteries included" port of Reduxjs for Kotlin+Android
Komprehensions - Do comprehensions for Kotlin and 3rd party libraries [STABLE]
redux-kotlin - Predictable state container for Kotlin apps
