LangSmith Deployment is now LangSmith Agent Server.
This page covers how your agents run in production with LangSmith Agent Server.Where you run LangSmith for observability, evaluation, and prompt engineering is separate; refer to Platform setup for details.
Deployable products
LangSmith Agent Server is framework-agnostic, which means you can deploy agents built with:LangGraph (and LangChain)
Use the LangGraph CLI and app templates to deploy an application to LangSmith.
Google ADK
Deploy Google Agent Development Kit (ADK) agent as a LangGraph with the
deployments-wrap-sdk package.Other frameworks
Deploy Claude Agent SDK, Strands, CrewAI, AutoGen, and other agent frameworks with the Functional API or
deployments-wrap-sdk.Agent Server hosting environments
Pick an environment based on where you want the control plane and data plane (Agent Servers and their databases) to run. All infrastructure types use the same Agent Server runtime.Cloud
Fully managed by LangChain on AWS, Azure, and GCP. Create deployments from GitHub in the LangSmith UI or with
langgraph deploy. Requires a Plus plan or above.Self-hosted with control plane
Run the LangSmith Agent Server control plane and Agent Servers in your own Kubernetes cluster, alongside self-hosted LangSmith. Requires the Enterprise plan with Agent Server hosting enabled.
Hybrid
LangChain-managed control plane with Agent Servers and their data plane in your infrastructure. Traces flow to LangSmith Cloud or self-hosted LangSmith.
Standalone server
Deploy Agent Server with Docker, Compose, or Kubernetes. Bring your own PostgreSQL, Redis, and LangSmith license; no control plane. Optional LangSmith tracing to Cloud or a self-hosted instance.
Common setups
- Managed hosting for your agents. LangSmith Agent Server on Cloud. LangChain hosts the control plane, data plane, and databases. Pairs with LangSmith Cloud.
- Agents in your VPC, control plane managed. LangSmith Agent Server via Hybrid. LangChain hosts the control plane; you host Agent Servers and their data plane. Pairs with LangSmith Cloud or self-hosted LangSmith.
- Full data residency or air-gapped. Self-hosted Agent Server hosting. You host the control plane and Agent Servers in your own infrastructure alongside self-hosted LangSmith.
- Agent runtime only, no control plane. Standalone Agent Server. Run Agent Server containers with Docker or Kubernetes without a control plane, optionally sending traces to LangSmith Cloud or self-hosted.
Understand deployment pricing
Deployments on LangSmith Cloud are billed on the compute and database resources that each deployment requests.Deployments on LangSmith Cloud require a Plus or Enterprise plan. For more information, see the pricing page.
LangSmith Agent Server billing
See the rates, the hourly cost of each deployment size, and ways to reduce deployment costs.
After deployment
Once deployed, agents work with Agent Server’s execution model: assistants for configuration, threads for state, and runs for workloads. For capabilities, tutorials, server customization, and operations, see Agent Server.Update prompts and contexts without redeploying
Manage the prompts and versioned contexts your deployed agents pull at runtime, so you can change behavior without a full deploy.
Interact with your deployment using RemoteGraph
Call your deployed graph from client code as if it were a local compiled graph.
Find and fix failures with Engine
Once agents are in production, use LangSmith Engine to detect recurring failures in their traces, diagnose root causes, and resolve them.
Full-stack web apps
Ship a LangChain.js agent and chat UI together as a single web app. The Vite example uses LangSmith Agent Server as the agent backend behind a separate UI. Other examples embed the agent inside the web framework’s route handlers and ship to the host platform.Full-stack web apps
Ship a LangChain.js chat app: embed the agent in Next.js, SvelteKit, Nuxt, Cloudflare Workers, or Deno Deploy (no Agent Server required), or pair LangSmith Agent Server with a Vite + React UI.
