onprem.ai: sovereignty score and 8 European alternatives

onprem.ai is a software platform for running language models and other AI on your own servers as a replacement for cloud AI services. The software connects servers, GPUs, models, APIs, monitoring and updates in one environment. It offers a catalogue of tested models, REST APIs compatible with OpenAI and Anthropic, a web interface for administration and usage insight, and support for agents, RAG and MCP. The vendor supplies the platform together with GPU servers or as software only for existing hardware, including air-gapped environments.

onprem.ai is a product of Onprem Technologies GmbH, headquartered in Schaffhausen, Switzerland. Switzerland is not an EU member state but is an EFTA country with an EU adequacy decision for data protection. According to the vendor, requests are processed entirely on premises, so no data leaves the company; the location is therefore that of your own infrastructure. No open-source licence is stated. The privacy policy refers to the GDPR and Swiss law.

Why digital sovereignty matters with onprem.ai

onprem.ai is headquartered in Switzerland and falls under Swiss law, including the revised Swiss data protection act. Switzerland is not an EU member, but the European Commission recognises its level of data protection as adequate. Its Swiss headquarters does not by itself bring it under US legislation such as the CLOUD Act.

onprem.ai 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.

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