Hosting LangSmith

This section covers how to host and manage LangSmith: the control plane, data plane, and backing services that power agent deployments and observability.

You’ll learn how to deploy LangSmith in one of three modes:

• Cloud: fully managed by LangChain
• Hybrid: LangChain manages the control plane; you host the data plane
• Self-hosted: you manage the full stack within your infrastructure

Start here if you’re deploying or maintaining LangSmith infrastructure.

Cloud

Run all components fully managed in LangChain’s cloud.

Get started

Hybrid

(Enterprise) Manage the data plane running in your cloud while LangChain manages the control plane.

Set up Hybrid

Self-hosted

(Enterprise) Run the full LangSmith or run standalone LangGraph Servers without the control plane UI.

Run self-hosted
