Redash suits SQL-fluent teams that want a light, permissively licensed tool for turning queries into charts, dashboards and alerts on their own servers. There is no vendor support or hosted option any more and releases are infrequent, so plan to apply security releases promptly and weigh a more actively developed tool for long-term use.
Overview
Redash is a web application built around a query editor: you write SQL (or a source's native query language) with a schema browser and autocomplete, visualise the result and combine visualisations into dashboards. Alerts notify you when a query result meets a condition, and the README states that everything in the UI is also available through the REST API. It supports more than 35 SQL and NoSQL data sources.
Databricks acquired Redash in June 2020 and closed the hosted service at the end of November 2021. In April 2023 the project was rebooted on GitHub as a community-led effort with volunteer maintainers; releases since then include v25.1.0 (January 2025), v25.8.0 (August 2025), v26.3.0 (March 2026) and v26.9.0 (September 2026), which fixed 13 security advisories. Self-hosting uses Docker images with PostgreSQL and Redis.
Key features
- SQL and NoSQL query editor with schema browser and autocomplete
- Visualisations from query results, combined into dashboards
- Scheduled query refresh, with alerts on query results
- Query parameters for reusable queries (scheduling parameterised queries is not supported)
- REST API covering everything available in the UI
- More than 35 built-in data sources, including Cloudflare D1 added in v26.9.0
Pros and cons
Pros
- Permissive BSD-2-Clause licence
- Simple workflow from SQL query to chart and dashboard
- Many SQL and NoSQL data sources built in
- Full REST API for automation
Cons
- No vendor-backed hosted service or commercial support since 2021
- Infrequent, community-run releases; security fixes arrive in batches
- No graphical query builder or semantic layer for users who do not write SQL
- The documented AWS and GCE images are old (version 8), so Docker is the practical install path
Pricing
Redash is free and open source under the BSD-2-Clause licence; you self-host it and pay only for infrastructure. There is no vendor-run hosted service or paid plan: the hosted service at app.redash.io closed on 30 November 2021.
Pricing checked on the vendor's official page on 7 November 2026. Prices change; confirm before buying.
Who it is best for
SQL-fluent teams that want a lightweight, self-hosted, permissively licensed query-to-dashboard tool and can maintain it themselves.
Who should look elsewhere
- Teams that need vendor support, a hosted service or self-service for non-SQL users: see the best open source BI tools.
- Pixel-perfect or parameterised scheduled reporting: see the best SQL reporting tools.
Verdict
Redash remains a straightforward, BSD-licensed way to share SQL results as dashboards and alerts, and the community has kept shipping releases. With no vendor behind it and a slow release cadence, it fits teams comfortable owning upgrades and security patching; others should look at more actively developed open source BI tools.
Frequently asked questions
Is Redash still maintained?
Yes, by community maintainers. The project was rebooted as a community-led effort in April 2023, and v26.9.0 was released on 24 September 2026 with fixes for 13 security advisories. Releases are infrequent.
What happened to hosted Redash?
After Databricks acquired Redash in June 2020, the hosted service at app.redash.io closed on 30 November 2021. Redash recommended Databricks SQL for Databricks users and self-hosted open source Redash for everyone else.
Is Redash free?
Yes. It is open source under the BSD-2-Clause licence. You run it yourself with Docker, PostgreSQL and Redis.
