CHAOSS

aid: chaoss
name: CHAOSS
kind: opensource
description: 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.
