Upsun: sovereignty score and 8 European alternatives

Upsun, formerly known as Platform.sh, is a cloud application platform for development teams. Applications are deployed through Git, with a preview environment for every branch, a CLI and API, scaling without downtime and observability. Supported stacks include Python, Node.js, PHP, Ruby, Java, Go and .NET. A second product, Upsun Dispatch, offers workflows for teams and AI agents. Upsun is delivered as a hosted service and is not open source.

Upsun is operated by Platform.sh SAS, a French company with its registered office in Paris. The platform runs on infrastructure from AWS, Google Cloud, Microsoft Azure, IBM Cloud and OVHcloud, and customers pick a region. European regions include France (OVHcloud and Azure), Germany, Ireland, Sweden, Switzerland and the United Kingdom; there are also regions in North America and Australia. A European region on a US hyperscaler still involves a US provider, whereas the OVHcloud region does not.

Why digital sovereignty matters with Upsun

Upsun 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.

Upsun hosts data in EU, US, OTHER. 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.

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