Your AI Agent Just Failed in Production. Where Do You Even Start Debugging?
Current tooling handles this poorly. LangSmith loses visibility when agents cross framework boundaries: CrewAI agent traces fail to appear in LangSmith entirely, even with tracing enabled. Langfuse shows wrong inputs per agent in supervisor orchestration, and users report identical generation names make it "impossible to target accurately a specific agent" when configuring per-agent evaluations. Arize Phoenix requires manual context propagation for multi-agent trace consolidation.

I Evaluated Every AI Agent Observability Tool on the Market. Here's What's Actually Missing.
LangSmith can trace LangChain applications natively, but CrewAI traces fail to appear in LangSmith entirely despite correct environment configuration, and unified cross-framework traces (a LangChain agent handing off to a CrewAI agent in the same trace) remain unsupported.

95% of AI Pilots Fail. The Ones That Succeed All Do This One Thing.
LangSmith can now trace individual CrewAI and AutoGen applications via OpenTelemetry, but it still cannot produce unified cross-framework multi-agent traces — a pipeline where a LangChain agent hands off to a CrewAI agent in the same trace breaks due to context propagation gaps.
