Langflow: sovereignty score and 8 European alternatives

Langflow is a low-code environment for building AI agents and retrieval-augmented generation (RAG) applications. Teams assemble flows visually from components for language models, vector databases and tools, and can expose them as an API or as an MCP server. The software is released under the MIT licence and runs locally, in Docker, as a desktop app for Windows and macOS, or through a hosted Langflow Cloud account.

Langflow was acquired by DataStax in 2024, and DataStax was in turn acquired by IBM, with the deal closing at the end of May 2025. The project is therefore under US ownership, and the hosted cloud service falls under US jurisdiction, including the CLOUD Act. Because the code is open source, a European organisation can run Langflow on its own infrastructure and decide which models and vector stores it connects, which keeps data and keys under its own control. The product website does not state where the hosted Langflow Cloud stores data.

Why digital sovereignty matters with Langflow

Langflow 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.

Langflow hosts data outside the EU (US). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

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