Redash
Self-hosted SQL and NoSQL query editor, visualizations and dashboards, with 35+ data source connectors.
Business Intelligence
Redash is a browser-based query and dashboard tool that you run on your own server: SQL and NoSQL queries with a schema browser and auto-complete, drag-and-drop visualizations, dashboards, scheduled refreshes, alerts and a REST API that exposes everything the interface can do. One edition exists today — the self-hosted release under BSD-2-Clause, free, with no paid or managed tier on sale. That is a fact the vendor documents rather than hides: its own end-of-life page says hosted Redash at app.redash.io was shut down on 30 November 2021, no new sign-ups were accepted, customer data was deleted thirty days later, and the company moved its paid focus to Databricks SQL, telling anyone who needs third-party data sources to self-host the open source version. Upstream is still alive — releases and commits continue through 2026 and the repository is not archived — but nobody supports your installation: you own the upgrades of the application, PostgreSQL, Redis and the container images, on a Linux host or VM, with no supported Windows deployment.

Limits, notes & source
Self-hosted (BSD-2-Clause)
- Limits
- Queries, visualizations, dashboards, scheduled refreshes, alerts and the REST API, with no seat limit. Needs PostgreSQL, Redis and background workers beside the application; the vendor recommends at least 4 GB of RAM for a basic deployment.
- Notes
- GitHub's licence API reads the repository LICENSE as spdx_id "BSD-2-Clause". There is no price to record because no paid edition is on sale: redash.io/pricing redirects to a home page with no plan or sign-up, and the vendor's own FAQ says of the open source version that "you can host for yourself free of charge".

Pros & cons
Strengths
- BSD-2-Clause source with no lock-in: the vendor invites you to customise, extend and contribute back. Source
- A REST API mirrors what the interface can do, so queries, dashboards and alerts can be scripted. Source
- Native support for more than 35 SQL and NoSQL data sources, extendable through the data source API. Source
Trade-offs
- The hosted service at app.redash.io shut down on 30 November 2021: self-hosting is the only option. Source
- The vendor moved its paid focus to Databricks SQL, so upstream has no commercial backing behind it. Source
- You own the upgrades: the application, PostgreSQL, Redis and the container images are yours to maintain. Source
