European Alternatives to LangChain
US framework and platform for building and operating LLM applications. Below are 3 alternatives from companies headquartered in Germany, Italy and the Netherlands. 1 of them keeps data in the EU only, and 2 have a free plan.
Headquartered in Europe
Every company listed here has its headquarters in the EU, EEA, UK or Switzerland, not just a data centre there.
Data location you can check
The pricing table shows whether each one keeps data in the EU only, offers an EU region, or does not say.
Outside the US CLOUD Act
US providers can be ordered to hand over data held in their European data centres. A European company with no US parent or US operations is outside that reach.

3 European Alternatives
deepset
Berlin sovereign AI platform for building, running, and governing production AI agents with full data and infrastructure control.
Memory Model is an Italian AI company building infrastructure for AI memory and retrieval-augmented generation (RAG). The platform helps developers build AI applications that can store, retrieve, and reason over large knowledge bases — essentially giving LLMs long-term memory and access to proprietary data. Memory Model provides vector storage, knowledge graph construction, and semantic search optimized for AI workloads. The platform is designed as a European alternative to US vector database companies like Pinecone and Weaviate, with EU-hosted infrastructure.
Orq.ai is a Dutch LLM operations platform that helps development teams build, test, deploy, and monitor AI-powered applications. The platform provides a centralized workspace for managing prompts, evaluating model outputs, running A/B tests, and monitoring production LLM performance. Orq.ai supports all major LLM providers and enables teams to switch between models without code changes. The platform is designed for engineering teams building AI features into their products who need observability, version control, and quality assurance for their LLM integrations.
What to Check Before Switching from LangChain
Where your data will be stored
1 of the 3 alternatives here says it keeps data in the EU only. deepset offers an EU region alongside others, so choose it explicitly when you set up the account. Memory Model does not state where data is stored. Ask before you move anything sensitive.
How you can try it
Memory Model and Orq.ai have a free plan, so you can run a real test before cancelling LangChain. deepset sells on custom quotes only, which usually means a sales call before you can try it.
Open source
deepset releases its software or models under an open licence, which makes it easier to self-host, inspect what runs, and move again later.
Security certifications
We have not confirmed a security certification for any of these alternatives yet. If your procurement requires ISO 27001 or SOC 2, ask each vendor for its documentation.
What you need to bring from LangChain
List the data, templates and integrations you rely on in LangChain, then confirm each one can be exported and that the alternative can import it or offers an API to rebuild it.
