Which one should you pick?

RATH

Automated data analysis and visualisation, augmented analytics. Its AGPL-3.0 license keeps the project and its forks open-source forever, and commercial use is allowed. Because it is self-hostable, your data can stay entirely on your own infrastructure.

Apache Superset

Enterprise-grade BI platform with rich charts and SQL lab. Its Apache-2.0 license is permissive — free to use commercially, embed and modify. Because it is self-hostable, your data can stay entirely on your own infrastructure.

Metabase

The easiest way to let everyone in the company query data. Its AGPL-3.0 license keeps the project and its forks open-source forever, and commercial use is allowed. Because it is self-hostable, your data can stay entirely on your own infrastructure.

Redash

Query, visualize and share data from many sources. Its BSD-2-Clause license is permissive — free to use commercially, embed and modify. Because it is self-hostable, your data can stay entirely on your own infrastructure.

Switching from Tableau without the drama

1. Export your data from Tableau first — most tools above can import standard formats.
2. Run your top pick in parallel for a week or two before committing; self-hosted options can be tried locally in minutes.
3. Migrate one team or one project at a time, keeping the old account read-only until everything checks out.
