Starlake: sovereignty score and 8 European alternatives

Starlake is a Paris-based company that develops open-source data infrastructure for data pipelines and analytics. Starflow is declarative: each table is described in a YAML file, from which native SQL pipelines are generated for DuckDB, BigQuery, Snowflake and Redshift, among others. Quack on Demand is an open-source control layer for fleets of DuckDB instances, with a governed SQL gateway. Both products are distributed as software under the Apache 2.0 licence and can be run on your own infrastructure.

According to its privacy policy, the company is based in Paris, at Quai de Valmy, and describes itself as the data controller under the GDPR. The policy names no parent company and no hosting region for the company's services. Because the products are open-source software that users operate themselves, the location of data is set by the deployment; a European organisation can keep pipelines and data warehouses within its own cloud or on-premises environment. Alongside the software, the company offers paid services, which its public pages do not describe in detail.

Why digital sovereignty matters with Starlake

Starlake is headquartered in FR and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Data is hosted exclusively in the EU, so Starlake scores best on data residency.

Starlake is open source. You can audit the source code, self-host the software and keep the encryption keys under your own control. Switching is easier because data and software are not tied to a single party.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Starlake together with your other vendors and gives a total score, a heatmap and the main risk drivers.
