About Apache Superset
Open-source BI for teams that want a chart library on top of SQL they already write.
Apache Superset started as a hackathon project at Airbnb by Maxime Beauchemin in 2015 under the name Caravel, was donated to the Apache Software Foundation as an incubator project in 2017, and graduated to top-level Apache project status in 2021. It is licensed under Apache 2.0, runs self-hosted on your own infrastructure, and connects to 70+ SQL databases, including Snowflake, BigQuery, Redshift, Postgres, MySQL, ClickHouse and DuckDB. The commercial flavour is Preset, the company Beauchemin founded, which offers a managed Cloud edition and contributes the majority of commits back to the project.
The appeal in BE/NL is straightforward: a chart library, a SQL Lab editor, dashboards and a virtual-dataset model, all without a Tableau or Power BI per-seat bill. Data-engineering-heavy teams reach for it because the dataset model is plain SQL and YAML, not LookML or DAX, and because every chart can also be authored as a saved query. The trap, in mid-market deployments we see, is the same as with every BI tool: pointed at three operational databases instead of one curated warehouse, the SQL Lab queries multiply, virtual datasets pile up, and the dashboards start contradicting each other. We feed Superset from one warehouse so the dataset model stays small, the cache hits land where they should, and the upgrade story stays manageable.
