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.

The "Services" design pattern
That depends on the API of the library in question. For example, there's hpqtypes-effectful that gives you a DB effect and functions that make use it can perform queries that will by default run in a single database transaction.

Implicit parameters vs ReaderT
I ended up using a different approach to guiding inference in my project, but I still thought the IP way was cool
- Comparing ZIO to Haskell effects libraries like Polysemy?

Effect Zoo for Scala 3
Consider 2 Haskell projects: Cleff and Effectful. They both are extensible effect systems, built around ReaderT design pattern. At their core, they use fused ReaderT + IO monad, with extensible environment. This architecture is very similar to ZIO's. All 3 even share the same limitation - inability to express nondeterminism (not very relevant fact, but I just want to emphasize the similarity).

[ANN] effectful - an easy to use, performant extensible effects library
cleff and effectful are very similar, to the point that I offered to join forces (for the record, majority of the conversation refers to things that are no longer true for both libraries as we inspired each other to fix most quirks :). The main difference is the internal environment - in effectful it's mutable, while in cleff it's immutable. All differences pretty much grow from this. The main ones:
