Redash — Connect, query, visualize, and share your data

What is Redash?

What it is

Redash is an open-source business intelligence and data analytics platform built with Python and JavaScript. It enables users to connect to diverse data sources, write and execute SQL/NoSQL queries, build visualizations, and share interactive dashboards—all through a browser-based interface.

It solves the problem of fragmented, inaccessible data by providing a unified workspace where teams can explore data without needing deep technical expertise or installing complex software. Organizations use it to replace or supplement expensive proprietary BI tools, enabling broader data literacy and self-service reporting across engineering, product, and business roles.

Key capabilities

  • Connect to over 35 SQL and NoSQL data sources including PostgreSQL, MySQL, BigQuery, Snowflake, MongoDB, Elasticsearch, and Athena
  • Compose and execute queries via a browser-based editor with schema browser and auto-complete
  • Create and combine visualizations (charts, tables, gauges, maps) into customizable dashboards using drag-and-drop
  • Schedule automatic query and dashboard refreshes at defined intervals
  • Set up alerts to notify users when query results meet specific conditions
  • Share visualizations and queries via shareable URLs with embedded permissions and comments
  • Access all UI functionality programmatically via a REST API

Who uses it and how

Engineering teams run ad-hoc data explorations and monitor system metrics using integrations with databases and observability tools like Prometheus or ClickHouse.
Product and marketing analysts build recurring reports from sources like Google Analytics, Salesforce, and Snowflake to track KPIs and campaign performance.
Data teams deploy Redash internally to enable non-technical stakeholders to self-serve reports and dashboards, reducing reliance on centralized reporting teams.

Getting started

Deploy using Docker (redash/redash:latest) or pre-built images for AWS/GCE; install via package managers or from source with PostgreSQL as the backend database. Documentation and setup guides are at https://redash.io/help/.

When to use it — and when not to

Redash replaces paid BI tools for teams needing flexible, self-hosted analytics with broad data source support, but requires manual setup and maintenance of PostgreSQL, Redis, and optionally SMTP for alerts. It lacks native row-level security and advanced governance features found in commercial suites, making it less suitable for highly regulated environments requiring strict audit trails or multi-tenancy.
