Metabase
Business intelligence — dashboards and analytics without SQL.
AGPL-3.0 alternative to Tableau with question builder, visual query editor, interactive dashboards, and embedding. Connects to 20+ databases.
Apache Superset is itself already open source, released under the Apache 2.0 license and maintained as a top-level Apache Software Foundation project. It's a mature, SQL-centric data exploration and visualization platform used at scale by companies like Airbnb and Netflix.
Since Superset is already open, the useful comparison is which open-source BI tool fits your team better. Metabase is an open-source alternative aimed at letting non-technical users build dashboards without writing SQL, which is a different emphasis than Superset's SQL-heavy, engineer-oriented workflow.
