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.

I have decided to connect my future with Scala (if possible), need little advice
If you're using http4s, don't use ZIO. Yes, ZIO has an interop-cats module, so you can do this. But using http4s means you're working in the conceptual framework the Typelevel ecosystem is based on (and what interop-cats does can be characterized as "describe ZIO's implementation in those terms, so the Typelevel ecosystem can make heads or tails of it.") This is essentially all cost and no benefit: you can't avoid understanding the Typelevel ecosystem if you use http4s (at least, no more than you can by using cats-effect), and you don't get any of the value proposition of ZIO (interop-cats gives you Typelevel typeclass instances for the RIO type alias, which means your error channel is rooted in Throwable, and you're faced with the most complex part of the ZIO ecosystem: ZLayer, which the Typelevel ecosystem doesn't use and doesn't need). Finally the ZIO ecosystem is still quite immature, and this brings us to documentation. There is not (yet!) anything comparable to:
- Using FS2 alongside ZIO?

Friction-less scala - Tell us what is causing friction in your day-to-day life with Scala
These are necessarily oversimplifications. In particular, the ZIO ecosystem offers the relevant instances of cats-effect typeclasses to support use of the ZIO type in the cats-effect ecosystem.

Why Typelevel hates ZIO?
However, ZIO continues to offer cats-effect type classes and I certainly have no doubt cats-effect 3 continues to benefit from John's contributions. Furthermore, I likewise don't doubt the value of the ZIO ecosystem generally, and John's success in building the ZIO community speaks for itself. I personally have chosen to remain closer to the other, let's say "classical," pure FP ecosystems, partially for historical (or, if you prefer, "sunk cost") reasons, but partially because I'm satisfied the value of the Haskell/Typelevel/PureScript/fp-ts/etc. interplay warrants it.

Is it possible to use cats' monad transformers (OptionT, EitherT) with an effect type (F) that has >1 type parameter?
It seems that zio/interop-cats faces a similar issue.

I've had great experience with ScalaPB and even better with fs2-grpc (which builds on top of ScalaPB).

Working with polymorphic data models in a REST API
One way I've solved this is to use Protobuf contracts to serialize json with ScalaPB. They have a way implementing oneof that keeps each object individual and separate. Even if you don't decide to use PB, you can take some inspiration from the implementation.

Scala 3.0 serialization
You could try out protocol buffers. Not sure how stable it is, but I noticed they have a Scala3 version of their runtime library. (Disclaimer: I have not tried it out myself)
What are some alternatives?
When comparing interop-cats and ScalaPB you can also consider the following projects:
cats-effect - The pure asynchronous runtime for Scala
scodec - Scala combinator library for working with binary data
slick-cats - Cats instances for Slick DBIO
ScalaBuff - the scala protocol buffers (protobuf) compiler
fs2-grpc - gRPC implementation for FS2/cats-effect
µPickle - uPickle: a simple, fast, dependency-free JSON & Binary (MessagePack) serialization library for Scala
sbt-crossproject - Cross-platform compilation support for sbt.
