Apache Superset vs Instatus

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.

Instatus's REST API (`api.instatus.com`) lets a status-page owner script incident and maintenance updates, component status changes, and subscriber management for their own hosted status page. Every request must carry an `Authorization: Bearer <API_KEY>` header and a page ID from the dashboard, confirmed live via a 401 "API key is not sent in request header" response on an unauthenticated GET to `/v1/pages`; the same endpoint echoes a matching `access-control-allow-origin` on both a GET and a separate OPTIONS preflight sent with an Origin header, confirming the API is browser-callable. Instatus itself runs a permanent free-forever plan alongside paid per-project tiers, with no separate gate on API access.
