Apache Superset vs Redash

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.

Redash is an open-source query and dashboard tool that lets teams connect to a data source, write a query, and visualize the results without writing frontend code. Its REST API, documented live at redash.io/help/user-guide/integrations-and-api/api, authenticates each request with a per-user API key sent as `Authorization: Key <api_key>` and lets scripts create queries, trigger refreshes, and pull dashboard results as JSON. Redash Inc.'s hosted SaaS at app.redash.io was discontinued in 2021, so the project now ships only as free, self-hosted open-source software with no vendor-run instance to point the API at.
