Redash

Redash provides a browser‑based interface for connecting to a wide range of relational, NoSQL, and API data sources, allowing users to write SQL or NoSQL queries with schema browsing and auto‑completion. Queries can be turned into visualizations through a drag‑and‑drop editor, and multiple visualizations can be assembled into dashboards that are shareable via URLs or the public API. The platform supports scheduled query refreshes, alerting on defined conditions, and a REST API that mirrors UI functionality.

It is aimed at analysts, developers, and anyone needing to explore and present data without mastering complex software. By offering a single, self‑hostable instance that can be extended with additional data source connectors, Redash enables teams across an organization to collaborate on reports, review queries, and make data‑driven decisions.

The project is released under a BSD‑2‑Clause license, is free to use without subscription, and is maintained as a stable, open‑source utility. It includes built‑in support for more than 35 data sources and can be deployed on common cloud images or on‑premises.
