subarr

The coordination, measurement, and quality layer that subgen never had. A peer service for the *arr family that adds calibrated audio-language detection, provider success leaderboards, and (v1.1) an in-app Whisper tuning lab. Maintained by coaxk on GitHub, where it has earned 106 stars from the community.

It's actively developed around arr-stack, bazarr, docker, and is a solid reference for anyone building with these tools.
