LangSmith vs Langfuse vs LangGraph Studio: Which Gives You the Best Agent Graph View?
A direct comparison of how LangSmith, Langfuse, and LangGraph Studio visualize LangGraph, CrewAI, AutoGen, and OpenAI Agents SDK agent runs — and where each tool's graph falls short.
If you need to see your agent graph, your options differ significantly across the three most popular observability tools — and none of them work without instrumentation first.
| LangSmith | Langfuse | LangGraph Studio | ContextIQ | |
|---|---|---|---|---|
| Graph type | Tree + waterfall | Beta node-edge (LangGraph only) | Node-edge graph | Node-edge graph |
| Frameworks | LangChain, LangGraph | LangGraph (beta graph) | LangGraph only | LangGraph, CrewAI, AutoGen, OpenAI Agents SDK, Google ADK |
| Requires instrumentation | Yes | Yes | Yes | No |
| Requires live traces | Yes | Yes | Yes | No |
| Runs in browser | Yes | Yes | No — local desktop | Yes |
| Multi-framework graph | No | No | No | Yes |
Langfuse shipped its beta LangGraph graph view in February 2025 but has not extended it to CrewAI, AutoGen, or the OpenAI Agents SDK. LangGraph Studio renders a proper node-edge graph but is a local desktop application restricted to LangGraph only. LangSmith has no node-edge graph in the platform at all — only the tree view and Gantt chart. ContextIQ's Agent Workflow Visualizer generates a static graph from a schema you define — no SDK, no traces, no live traffic required — and works across all five frameworks.
