Instatus vs Redash

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.

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.
