What is Redash?

Redash is a web-based tool for connecting to databases and data warehouses, then turning that data into visual reports and dashboards. You write SQL queries to pull data from your sources, then use Redash's visualisation tools to create charts, tables, and other graphics that help you spot patterns and trends. It's designed for teams that need to share data insights without requiring everyone to know SQL or set up complex reporting infrastructure. The tool handles the repetitive work of querying and formatting data, so analysts and business users can focus on interpretation rather than technical setup.
