Overview
LangChain provides an open agent engineering platform and open source frameworks for building agent systems. It is used to control models, context, deployment, evaluation, and observability across the agent development lifecycle.
The platform includes LangSmith for observability, evaluation, deployment, sandboxes, a gateway for controlling model calls, and no-code agents. It also includes open source frameworks such as deepagents, LangGraph, and LangChain for different levels of agent control and complexity.
It is built for companies and teams that want to adapt agent behavior to their own workflows, policies, and tools, and keep improving it in production.
