Countly vs Drupal.org

Countly is an open-source product analytics platform you self-host (or run as their managed cloud), ingesting events over a REST Data API keyed by a per-app `app_key` rather than a private secret — a live unauthenticated POST to a running Countly server (try.count.ly/o) confirmed the endpoint only demands `app_key`, returning a `missing_api_key` JSON error otherwise. The Community Edition is free and self-hostable under an AGPLv3-derived license; Countly also sells a paid Enterprise Edition with SSO, extra data sources, and dedicated support.

Drupal.org exposes its community project and node data through a legacy Drupal 7 REST endpoint (`drupal.org/api-d7/node.json`); a live unauthenticated GET returned a 200 JSON body with `Access-Control-Allow-Origin: *`, resolving cors "unknown" to "yes". It's a free community resource run by the nonprofit Drupal Association, with no authentication or paid tier for reading published project data.
