CHAOSS

CollectOSS REST API

CollectOSS (pronounced "collect us") is the CHAOSS reference data collection and storage tool for open source community health. It harvests data from GitHub and GitLab forges into a PostgreSQL schema and exposes a Flask/Gunicorn REST API of 137 operations that return CHAOSS-aligned metrics grouped by the CHAOSS focus areas — evolution, risk, value, complexity, experimental — plus utility, visualization, DEI Badging and OAuth login endpoints. It is the successor to Augur, which left the CHAOSS project in March 2026; CollectOSS is self-hosted, so each deployment serves the API from its own host under /api/unstable/.
