+This guide shows you how to deploy **standalone <Tooltip tip="The server that runs your LangGraph applications.">Agent Servers</Tooltip>** directly, without using the [LangSmith control plane](/langsmith/deploy-with-control-plane). You can deploy the server independently and still use LangSmith separately for tracing and evaluation. Standalone servers are production-ready and provide the most lightweight self-hosting option for running agents.

-**This is the setup page for deploying Agent Servers directly without the LangSmith platform.**

-Review the [self-hosted options](/langsmith/self-hosted) to understand:
-- [Standalone Server](/langsmith/self-hosted#standalone-server): What this guide covers (no UI, just servers).
-- [LangSmith](/langsmith/self-hosted#langsmith): For the full LangSmith platform with UI.
-- [LangSmith Deployment](/langsmith/self-hosted#enable-langsmith-deployment): For UI-based deployment management.
