Telemetry meets higher-kinded types

otel4s is an OpenTelemetry implementation for Scala. The design goal is to fully and faithfully implement the OpenTelemetry Specification atop Cats Effect.



The API is still highly experimental, but we are actively instrumenting various libraries and applications to check for fit. Don't put it in a binary-stable library yet, but we invite you to try it out and let us know what you think.
