Langfuse Observability
Overview
Langfuse is the open-source LLM observability platform that OrchestKit uses for tracing, monitoring, evaluation, and prompt management. Unlike LangSmith (deprecated), Langfuse is self-hosted, free, and designed for production LLM applications.
When to use this skill:
- Setting up LLM observability from scratch
- Debugging slow or incorrect LLM responses
- Tracking token usage and costs
- Managing prompts in production
- Evaluating LLM output quality
- Migrating from LangSmith to Langfuse
OrchestKit Integration:
- Status: Migrated from LangSmith (Dec 2025)
- Location:
backend/app/shared/services/langfuse/ - MCP Server:
orchestkit-langfuse(optional)
