Redash is an open-source tool for connecting to databases, running SQL queries, and creating visual dashboards.

Redash is an open-source, browser-based data visualization and dashboarding tool that allows users to connect to multiple data sources, write SQL queries, and build interactive dashboards. Founded in 2013 by Arik Fraimovich, the project was initially developed to solve internal data exploration needs at a previous startup. It was later acquired by Databricks in 2020, but the open-source project on GitHub remains independently maintained by a community of contributors.

As of June 2026, the GitHub repository has over 28,600 stars and 4,600 forks, with 7,967 commits. The project is written in Python and JavaScript, and its latest commit on June 1, 2026, fixed a security vulnerability (CVE-2025-7783) by upgrading the form-data dependency. Redash does not have a corporate entity or disclosed revenue; it is purely a community-driven open-source project.

Its primary users are data analysts and engineers who need a lightweight, self-hosted alternative to commercial business intelligence tools. The project has no known funding rounds, paid products, or named enterprise clients in the public record. Recent development activity includes a major frontend stack update in March 2026, upgrading Node.js to version 24, switching from yarn to pnpm, and updating Python to version 3.13. The project's long-term viability depends on continued community contributions and the goodwill of its maintainers, as there is no commercial entity backing its development.
