LangSmith: Agent Deployment Infrastructure for Production AI Agents
LangSmith Deployment
Run agents at scale
LangSmith Deployment is purpose-built infrastructure for running agents in production and standardizes how your organization builds, deploys, and governs agents.
Helping top teams ship great agents
Three ways to build, from full harness to full control
Each package solves a different problem. Choose where you want to start, then compose the rest of the stack around it.
APIs
APIs to handle real-world agent interactions
Run human-in-the-loop approvals, background tasks, and multi-agent coordination on a durable runtime with built-in fault tolerance.
- Deploy with one click
- Production-ready APIs for HIL, memory, and conversation threading
- Stream type-safe messages, UI components, and custom events
Standardize
Align agent deployment, org wide
Manage agents through a centralized registry with versioning, instant rollbacks, and native A2A, MCP, and Agent Protocol support.

Workloads at scale
Scale without rebuilding infrastructure
Running agents gets harder at scale. Handle bursty, long-running, and complex agent workloads with horizontal scaling.
Infrastructure for production agents
Every agent in production faces the same needs: durable execution, streaming, state and task management. LangSmith Deployment ships with all of it, so you spend your time on your agent logic instead of rebuilding the wheel.
One-click deploy
Deploy your agent in one click and get durable execution, state, and streaming out of the box.
