Coalesce: sovereignty score and 8 European alternatives

Coalesce is a data transformation, catalogue and data quality platform with which data teams build, automate and govern transformations. Work can be done in the web interface, in code, or with AI agents via MCP. The platform runs on top of Google BigQuery, Databricks, Snowflake and Microsoft Fabric (Amazon Redshift is in private preview) and offers lineage, impact analysis, documentation and in-pipeline testing, among other things. Coalesce is delivered as SaaS, complemented by Coalesce Desktop for local development.

Coalesce Automation, Inc. is a US company with an address in San Francisco and falls under US jurisdiction, including the CLOUD Act. According to its data processing addendum, processing takes place in Google Cloud Platform data centres, and Coalesce may transfer data outside the EEA, the UK and Switzerland, with standard contractual clauses applying. Coalesce is proprietary and not open source. For a European organisation, this means transformation logic and metadata fall under a non-European provider, while the data itself can remain in its own data platform.

Why digital sovereignty matters with Coalesce

Coalesce is headquartered in the United States. US vendors fall under the CLOUD Act and FISA 702: US authorities can compel access to data, even when that data sits in a European data centre. That is the core of the jurisdictional exposure in our model.

Coalesce hosts data in US, EU. Exactly what stays within the EU — and what does not — is defined by the vendor's data processing agreement and sub-processor list, not by a setting you control yourself; check those documents for the precise scope, including backups, logs and support access.

Coalesce is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

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