Lunary: sovereignty score and 8 European alternatives

Lunary is a platform for teams that build applications and chatbots on large language models. It records logs and traces of model calls, provides analytics, manages prompt templates with versioning, supports evaluations and offers PII masking. It is available as a cloud service and can also be self-hosted with Docker, Docker Compose or Kubernetes. According to the project README, the code is licensed under Apache 2.0.

Lunary is operated by Lunary LLC, a Delaware company with an address in San Francisco, so it is headquartered in the United States. The privacy policy states that data for the cloud version is hosted in the EU, and the data processing agreement names Hetzner and Google Cloud in Germany as hosting sub-processors. Other sub-processors, for example for error monitoring, analytics and AI features, are located in the United States. Self-hosting keeps traces and prompts entirely in your own infrastructure. For a European organisation the US company seat is relevant for jurisdiction questions even with EU hosting, and self-hosting removes the vendor from the data path.

Why digital sovereignty matters with Lunary

Lunary is headquartered in the United States. US vendors fall under the CLOUD Act and FISA 702: US authorities can compel access to data, even when that data sits in a European data centre. That is the core of the jurisdictional exposure in our model.

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

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