There is also https://github.com/valskalla/odin https://github.com/valskalla/odin for a pure/fp Scala logging library (also includes a slf4j bridge if you need to work with java stuff) It also has some "fancy" features like changing log level if exception happens https://github.com/valskalla/odin#extras-conditional-logging https://github.com/valskalla/odin#extras-conditional-logging Though we have not yet upgraded it to Scala 3 it should work with Scala 3 just fine. (We do compile a Scala 3 release of most of the stuff but the codebase itself is mostly Scala 2 for now)
