for ai agent observability tool
LangSmith→Langfuse
On 2026-08-14, Claude changed its #1 recommendation for best ai agent observability tool — dropping LangSmith from the top spot in favor of Langfuse. The previous #1 had held since 2026-07-15.
“The strongest all-around open-source choice for agent observability — OpenTelemetry-aligned tracing that captures nested tool calls, spans, and multi-step agent runs cleanly, plus built-in evals, prompt management, and datasets; framework-agnostic (OpenAI, LangGraph, LlamaIndex, CrewAI, custom) and fully self-hostable, which matters for teams with data-residency constraints. Near-tie with LangSmith at the top — Langfuse leads on openness and portability, LangSmith on agent-trace depth.”— Claude
