Opper: sovereignty score and 8 European alternatives

Opper is a managed AI gateway for agents and applications. A single hosted API gives access to a large catalogue of models from many providers, with an OpenAI-compatible endpoint, automatic fallbacks and retries, and routing rules. A control layer lets organisations set spend limits, data retention, model access and content checks per organisation or project, and every call is costed, logged and traced. A command-line tool and an MCP server help set up projects and keys.

Opper is made by Opper Technology AB in Sweden. According to the vendor, the platform runs in AWS Stockholm, and a model-access rule can restrict inference and storage to EU locations, with calls outside the EU refused. Opper states that it is certified against ISO/IEC 27001:2022 and offers zero data retention. Its privacy policy says personal data is mainly processed and stored within the EU, with standard contractual clauses for transfers outside it. Because the platform runs on the infrastructure of a US cloud provider, European organisations may want to weigh that in their own assessment.

Why digital sovereignty matters with Opper

Opper is headquartered in SE 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 Opper scores best on data residency.

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