We’ve had a busy February at Langfuse, filled with new integrations, features, and announcements. Here’s a quick rundown:
🔭 OpenTelemetry Support
Langfuse now includes an OpenTelemetry backend to receive OTel traces at: /api/public/otel
What is OpenTelemetry?
OpenTelemetry is an open-source observability framework for collecting and processing telemetry data. It includes Semantic Conventions, which standardize the naming and structuring of trace data.
We’re thrilled about this update because it enables integrations with a wide range of frameworks and languages that use the OpenTelemetry standard. This includes:
- CrewAI
- AutoGen
- Semantic Kernel
- Pydantic AI
- Spring AI
- Smolagents
- Other languages such as Java, Go, .NET

⚡ Open Source LLMOps Stack
We’ve partnered with LiteLLM to introduce the Open Source LLMOps Stack.
Selecting the right tooling stack is essential—avoiding vendor lock-in and high switching costs means you can continue to develop in rapid cycles.
Popular among Langfuse and LiteLLM users (especially in enterprise and regulated settings), this stack enables efficient observability without extensive instrumentation. LiteLLM further enhances the experience with virtual LLM keys, budgeting, failovers, and compatibility with over 100 LLMs through the OpenAI API schema.
