OpenTelemetry Tracing Support

Steffen Schmitz

Push your OpenTelemetry Spans to Langfuse

Langfuse now accepts spans from your OpenTelemetry instrumentation. OpenTelemetry provides a vendor-neutral standard for distributed tracing with GenAI-specific semantic attributes. This enables you to use Langfuse across more languages and frameworks than ever before.

Checkout our OpenTelemetry documentation to get started or dive into the guides for some of our newly supported libraries like OpenLIT and OpenLLMetry.

New frameworks supported via the OpenTelemetry endpoint include:

• Hugging Face smolagents
• CrewAI
• AutoGen
• Semantic Kernel
• Pydantic AI
