# LangSmith Deployment

> Deploy and manage agents with durable execution, real-time streaming, and horizontal scaling.

LangSmith Deployment is a workflow orchestration runtime purpose-built for agent workloads. It provides the managed infrastructure agents need to run reliably in production at scale, supporting the full lifecycle from local development to deployment. LangSmith Deployment is framework-agnostic: you can deploy agents built with LangGraph or [other frameworks](/langsmith/deploy-other-frameworks).

<Note>
  LangSmith Deployment requires a [Plus plan or above](https://www.langchain.com/pricing). [Get a demo](https://www.langchain.com/contact-sales) to learn more about BYOC deployment and premium support options.

## Agent deployment workflow

<Note>
  **Start here if you're building or operating agent applications.** This section is about deploying **your application**. If you need to set up LangSmith infrastructure, the [Platform setup section](/langsmith/platform-setup) covers infrastructure options.

## Capabilities

### Studio

[Studio](/langsmith/studio) connects to any Agent Server (local or deployed) and gives you an interactive environment for developing and debugging agents. Visualize execution graphs, inspect state at any checkpoint, step through runs, modify state mid-execution, and branch to explore alternative paths.

### Agent composition

Agents don't run in isolation. [RemoteGraph](/langsmith/use-remote-graph) lets any agent call other deployed agents using the same interface you use locally: a research agent delegates to a search agent on a different deployment, a routing agent dispatches to specialized sub-agents. The agents don't need to know whether they're calling something local or remote.

Native support for [MCP](/langsmith/server-mcp) and [A2A](/langsmith/server-a2a) means your deployed agents can expose and consume tool interfaces and agent-to-agent protocols alongside the broader ecosystem.

### Deployment options

* **[Cloud](/langsmith/deploy-to-cloud)**: Fully managed. Push from a git repo or use [`langgraph deploy`](/langsmith/cli#deploy).
* **[Hybrid](/langsmith/deploy-with-control-plane)**: Runs in your cloud, managed by the LangSmith [control plane](/langsmith/control-plane).
* **[Self-hosted](/langsmith/self-hosted)**: Fully self-managed in your own infrastructure.

Same runtime, same APIs. What changes is who manages the infrastructure. For a comparison, refer to [Platform setup](/langsmith/platform-setup).
