Data Residency

Where is your data stored and processed?

Langfuse: EU cloud region (Ireland) keeps data within EEA. Full self-hosting option allows air-gapped EU deployments with zero cloud dependency. Customer can choose exact data location.

AutoGen (Microsoft): MIT-licensed open-source framework. No vendor cloud—deploy entirely on your own EU infrastructure. Data residency is determined entirely by your chosen infrastructure. Maximum possible data sovereignty.

Legal Jurisdiction

Which laws govern the company and your data?

Langfuse: German GmbH (EU company) but acquired by ClickHouse Inc. (US). German law governs the entity but US parent introduces CLOUD Act considerations. Self-hosted deployment eliminates US cloud dependency.

AutoGen (Microsoft): Published by Microsoft (US), but MIT licence means the framework is infrastructure-independent. Self-hosted EU deployments are not subject to Microsoft's jurisdiction. Azure integration is optional and not required for the framework to function.

AutoGen (Microsoft): Fully self-hosted: complete control over all agent conversation data, code execution outputs, and task results. No data sent to Microsoft unless Azure OpenAI is chosen as the LLM provider.
