  CHAOSS (Community Health Analytics in Open Source Software) is a Linux
  Foundation project that develops metrics, methodologies, software, and
  practitioner guides for measuring and improving open source community
  health and sustainability. It produces a metrics catalog organized into
  focus areas (Common, DEI, Risk, Value, Evolution) and metrics models,
  along with open source software (Augur, 8Knot, GrimoireLab) that
  ingests data from Git, GitHub, GitLab, mailing lists, and other
  community platforms to compute the metrics. CHAOSS-aligned SaaS
  services such as OSS Compass and Bitergia Analytics also expose the
  metrics for adopters who do not want to host the software themselves.
