About
Sovereign European AI infrastructure with chat interface and inference API, hosting (frontier) open-weight models with servers on EU ground and EU companies in the stacks only.

The platform serves both, developers through an OpenAI and Anthropic compatible API and non-technical users through a chat interface with built-in tools like web search and code execution.

What does Melious AI do?
Melious AI is sovereign european ai infrastructure with chat interface and inference api, hosting (frontier) open-weight models. It is listed under ai, api, and infrastructure on EU Alts because its core functionality serves teams looking for a European ai tool with EU data residency, typically as a switch away from well-known US incumbents.
Is Melious AI a good European ai alternative?
Melious AI is a fit for European businesses evaluating ai options where data residency and GDPR alignment matter — typical buyers include EU-based SaaS teams, public-sector projects, regulated industries (healthcare, finance, legal), and any organisation that needs to demonstrate that customer data does not leave the EU. It also overlaps with api and infrastructure use cases.
Is Melious AI GDPR compliant?
Melious AI is headquartered in Saarbrücken, Germany and falls under EU jurisdiction, so it processes user data under the GDPR by default. Customer data processing is supervised by Germany's data protection authority, the Bundesbeauftragte für den Datenschutz und die Informationsfreiheit (BfDI). Because the company is not US-incorporated, it is not subject to the US CLOUD Act — meaning US authorities cannot compel Melious AI to disclose customer data the way they can with well-known US incumbents. For European buyers, that often simplifies DPIA paperwork and standard contractual clauses.
How do teams switch from well-known US incumbents to Melious AI?
Most teams move to Melious AI from well-known US incumbents because they want EU data residency without giving up the core ai workflow. Melious AI's Germany base means a single jurisdiction for both the company and (typically) its hosting infrastructure, so you can drop Schrems II transfer impact assessments for this part of your stack. Plan the migration in stages: export your data from the US incumbent, pilot Melious AI with a small team, then move the rest once the integration coverage you need is confirmed.
