OpenFaaS: sovereignty score and 8 European alternatives

OpenFaaS is a framework for building and running serverless functions on Kubernetes. Developers package functions as containers and deploy them with a command-line tool; the platform handles routing, scaling and metrics. It is aimed at teams that want functions-as-a-service on their own clusters and is delivered as software to install rather than as a hosted service. The project is maintained by OpenFaaS Ltd.

OpenFaaS Ltd is registered in England and Wales, so its seat is in the United Kingdom, outside the EU and EEA. The Community Edition is licensed under the OpenFaaS CE EULA, which requires a licence for commercial use; contributions from third parties are under the MIT licence. The project is therefore not open source in the OSI sense. Because the software runs on infrastructure the organisation controls, data location depends on the cluster. For a European organisation, the UK seat means the vendor is not established in the EU, and commercial use requires a licence from the vendor.

Why digital sovereignty matters with OpenFaaS

OpenFaaS 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.

OpenFaaS runs on infrastructure you choose and control yourself. You decide where the data lives, including fully within the EU if you want — this is not a fixed hosting choice made by the vendor.

OpenFaaS is closed source, but you run the software yourself on your own infrastructure. The encryption keys and the runtime therefore stay under your own control, though you cannot audit or modify the source code. Ask about export options and open standards to limit software-level lock-in.

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