Redash

Verified Jul 2026

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.

Auth quickstart

  1. Sign up with the provider to get an API key.
  2. Send it on every request as a headerAuthorization: <key>
  3. The exact header isn't documented — Authorization is a common default; confirm in the provider's docs.
Stored keyNo key stored

Your key is stored only in this browser (localStorage) and sent directly to the API — never to greatapis.
