    Effect Zoo for Scala (by marcinzh)

  • Effect Zoo - Code gallery & microbenchmark suite for effect systems.

  • effect-zoo

    Comparing Haskell effect systems for ergonomics and speed

  • Inspired by similarly named project for Haskell.

  • InfluxDB

    Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  • cleff

    Fast and concise extensible effects

  • 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).

  • effectful

    An easy to use, fast extensible effects library with seamless integration with the existing Haskell ecosystem.
