- [Rudder](https://github.com/normation/rudder) — an example about how to manage error ADT in several sub-projects and specialized sub-domains, and how one can gradually contextualize error messages in domain layers. Uses queues, brackets, interop with Java, and historical code. See [context and references](https://issues.rudder.io/issues/14870).
- [ZIO AI Platform Backend](https://github.com/Clover-Group/zio_front) — Clover Group AI Platform backend, which employs ZIO, Doobie, http4s and Kafka .
