CHAOSS

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.

CHAOSS publishes 4 APIs on the APIs.io network. Tagged areas include Analytics, Community Health, DEI, Linux Foundation, and Metrics.

CHAOSS’s developer surface includes documentation, GitHub presence, engineering blog, getting-started guide, YouTube channel, tooling, and 9 more developer resources.
