About gofr
GoFr is an opinionated Go framework for building microservices, aimed at Go developers and platform teams who want HTTP, gRPC, data access and observability built in rather than assembled from separate libraries.
About kotlin-logging
kotlin logging is a lightweight, pure Kotlin logging facade that gives JVM, Android, and multiplatform Kotlin applications lazy, idiomatic log calls while delegating the actual logging work to SLF4J and whichever backend implementation the project already uses.
