Leverages Scala's type system to catch JSON parsing errors at compile time, reducing runtime issues, as emphasized in the key features for type safety.

Provides automatic derivation of encoders and decoders for case classes and sealed traits, simplifying serialization without manual boilerplate.

Uses Jawn for fast JSON parsing, enabling efficient handling of high-throughput scenarios, as evidenced by adopters like Criteo processing hundreds of thousands of events per second.

Has a modular architecture with support for custom encoders and integrations with many Scala libraries, such as Akka, http4s, and Finch, shown in the extensive related projects list.
