Meltano: sovereignty score and 8 European alternatives

Meltano is an open-source data integration platform for ELT pipelines. Data teams define pipelines as code, keep them in version control, use pre-built connectors for SaaS applications, APIs, files and databases, and build custom connectors with the Meltano SDK for Singer. Transformations run with dbt. Meltano is available as Meltano Open, free to self-host, and as Meltano Cloud, a managed edition with built-in scheduling.

Meltano is an open-source project under the MIT licence, maintained by Matatika, a company with an office in London. Meltano Open runs on your own servers, so you decide where pipelines run and where data is stored, including inside the EU. For Meltano Cloud, the public pages reviewed state no hosting region; check this with the vendor before sending personal data. A London company is subject to UK law, not EU law.

Why digital sovereignty matters with Meltano

Meltano is headquartered in GB, outside the EU. Contracts and data therefore also fall under non-European law. The GDPR applies through contractual terms, but in a conflict with local legislation you have less certainty than with a European vendor.

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

Meltano 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 Meltano together with your other vendors and gives a total score, a heatmap and the main risk drivers.
