About | NVIDIA NeMo Relay

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	⚠️ Partial	❌ No	Hook-backed telemetry with pre-tool guardrails. Managed execution rewrites require the patch-based integration.

Guides

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

OpenClaw Plugin Guide covers configuring the OpenClaw plugin, mapping OpenClaw hooks to NeMo Relay telemetry, and understanding current LLM replay fidelity boundaries.
LangChain Integration Guide covers installing the LangChain extra and adding NeMo Relay middleware and callbacks to LangChain agents.
LangGraph Integration Guide covers installing the LangGraph extra and adding NeMo Relay callbacks to LangGraph workflows.
Deep Agents Integration Guide 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 instead.
