Redash

Redash is an open-source data visualization and collaboration tool that enables teams to query, visualize, and share data from multiple data sources through a single web interface. It combines a query editor, visualizations, and dashboards to support data exploration and decision making.

Redash connects to a wide range of data sources, including relational databases (PostgreSQL, MySQL, MSSQL), data warehouses (BigQuery, Redshift, Snowflake), search engines (Elasticsearch), NoSQL stores, and various APIs or CSV-like sources. Users can write SQL or native queries with syntax highlighting and autocompletion; query results can be cached for faster iterations. Visualizations such as charts, tables, and maps can be assembled into dashboards with filters and parameters for interactivity.

Dashboards can be shared via links or embedded in other apps, and access is controlled through roles and permissions. Redash also supports scheduled queries and alerting, enabling notifications when results meet certain conditions.

Deployment options include self-hosting and a hosted cloud service. The project is maintained by an open-source community and offers commercial products that provide enterprise features, security, and support. Redash is widely used to promote data-driven decision making across a range of organizations and industries.
