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.

Coroutines and Effects
Indeed - I do not think it is a coincidence that a lot of production experiments in effect systems are happening in Scala right now - the language is very flexible to conduct them. https://github.com/getkyo/kyo in particular looks interesting as it explores a different space where the monadic nature is less exposed to the end user.

Help a Kotlin convert back into Scala world
Now in scala we have direct mode transformers: dotty-cps-async [https://github.com/rssh/dotty-cps-async] with cps-async-connect [https://github.com/rssh/cps-async-connect ] supports all well-knowm monad stacks, for ZIO also exists ZIO-direct [https://github.com/zio/zio-direct ] , for IO - cats-effect-cps [https://github.com/typelevel/cats-effect-cps ], for kyo [https://github.com/fwbrasil/kyo ] - kyo-direct.

The Effect(s) Of Effect(s) by Flavio Brasil at Functional Scala 2022
Thanks! I'm not sure I understand your use case but it's possible to handle effects even if they aren't present in the computation. An example of that is KyoApp's run method. It handles several effects even thought the application might not use them:

I had a great experience with Scala and hopefully it will get more popular
scala has 2 healthy and pretty complete lib ecosystems : check out typelevel and ZIO. Both are FP oriented, which might not be your cup of tea at first glance but I would encourage you to try em out ! Softest introduction would be to start with the typelevel cats library and build up from there. The excellent Scala with Cats will ease you softly into an FP mindset. It's a bit dated and for scala 2 only but translating to Scala 3 is a very good exercise if you feel so inclined !

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.

Is Parallel Programming Hard, and, If So, What Can You Do About It? [pdf]
I use ZIO (http://zio.dev) for Scala which makes parallel programming trivial.
Wraps different styles of asynchronicity e.g. callbacks, futures, fibers into one coherent model. And has excellent resource management so you can be sure that when you are forking a task that it will always clean up after itself.
Have yet to see anything that comes close whilst still being practical i.e. you can leverage the very large ecosystem of Java libraries.

40x Faster! We rewrote our project with Rust!
The one advantage Rust has over Scala is that it detects data races at compile time, and that's a big time saver if you use low level thread synchronization. However, if you write pure FP code with ZIO or Cats Effect that's basically a non-issue anyway.
What are some alternatives?
Korolev - Single Page Applications running on the server side.
cats-effect - The pure asynchronous runtime for Scala
Binding.scala - Reactive data-binding for Scala
Monix - Asynchronous, Reactive Programming for Scala and Scala.js.
calico - Calico is a UI library for the Typelevel.js ecosystem. It leverages the abstractions provided by Cats Effect and FS2 to provide a fluent DSL for building web applications that are composable, reactive, and safe. If you enjoy working with Cats Effect and FS2 then I hope that you will like Calico as well.
