Apache Superset vs Google Analytics

Apache Superset is an open-source data-exploration and business-intelligence platform for building interactive dashboards and running ad-hoc SQL over dozens of database engines. Its REST API, documented at superset.apache.org/docs/api (confirmed live, redirecting to a 200 Swagger reference), exposes charts, dashboards, datasets, and database connections under `/api/v1/`, authenticated with a JWT access token obtained by POSTing credentials to `/api/v1/security/login` rather than a long-lived static key. Superset is self-hosted with no single Apache-run public instance, so HTTPS and CORS are configured per deployment rather than fixed by a vendor.

The Google Analytics 4 Data API (`analyticsdata.googleapis.com/v1beta`) lets applications pull custom reports of metrics, dimensions, and audience segments out of a GA4 property, complementing a separate Admin API used to manage properties, streams, and access. It requires a Google OAuth 2.0 bearer token, confirmed live via a `WWW-Authenticate: Bearer realm="https://accounts.google.com/"` challenge on an unauthenticated `runReport` call, and the same request repeated with an Origin header echoed `access-control-allow-origin` back, resolving CORS support from unknown to yes. The core Data API is free to call within Google's standard quotas, with Google Analytics 360 offered as a paid enterprise tier for higher limits and additional features.
