# About

Use this section when your application already uses a supported framework or
agent harness and you want the maintained NeMo Relay integration path for that
surface.

Supported integrations are end-user entry points. They use public framework or
plugin APIs where available and document the support level for observability,
security middleware, and optimization features.

## Support Matrix

| Agent / Library | Observability | Security | Optimization | Notes                                                            |
| :-------------- | :-----------: | :------: | :----------: | :--------------------------------------------------------------- |
| LangChain       |     ✅ Yes     |   ✅ Yes  |     ✅ Yes    | Wrapped tool and LLM calling.                                    |
| LangGraph       |     ✅ Yes     |   ✅ Yes  |     ✅ Yes    | Wrapped tool and LLM calling.                                    |
| Deep Agents     |     ✅ Yes     |   ✅ Yes  |     ✅ Yes    | Wrapped tool and LLM calling.                                    |
| OpenClaw        |     ✅ Yes     |   ❌ No   |     ❌ No     | Observability support; missing middleware for wrapped execution. |

## Guides

Use these guide links to move from the support matrix into setup and usage
instructions.

* [OpenClaw Plugin Guide](/supported-integrations/openclaw-plugin) covers configuring the OpenClaw
  plugin, mapping OpenClaw hooks to NeMo Relay telemetry, and understanding
  current LLM replay fidelity boundaries.
* [LangChain Integration Guide](/supported-integrations/langchain) covers installing the LangChain
  extra and adding NeMo Relay middleware and callbacks to LangChain agents.
* [LangGraph Integration Guide](/supported-integrations/langgraph) covers installing the LangGraph
  extra and adding NeMo Relay callbacks to LangGraph workflows.
* [Deep Agents Integration Guide](/supported-integrations/deepagents) covers installing the Deep
  Agents extra and capturing Deep Agents-specific marks, skills, subagents, and
  human-in-the-loop lifecycle events.

If you are building a new framework integration or patching framework internals,
use [Integrate into Frameworks](/integrate-into-frameworks/about) instead.
