# The agent engineering platform
# Documentation

Tools for every step of the agent development lifecycle. Ship reliable agents fast with open source frameworks for building agents, and our commercial platform LangSmith for observing, evaluating, and deploying agents.
LangChain is the platform for agent engineering. AI teams at Replit, Clay, Rippling, Cloudflare, Workday, and more trust LangChain's products to engineer reliable agents.

Our **open source frameworks** help you build agents:

- [**LangChain**](/oss/python/langchain/overview) helps you quickly get started building agents, with any model provider of your choice.
- [**LangGraph**](/oss/python/langgraph/overview) allows you to control every step of your custom agent with low-level orchestration, memory, and human-in-the-loop support. You can manage long-running tasks with durable execution.

[**LangSmith**](/langsmith/overview) is a platform that helps AI teams use live production data for continuous testing and improvement. LangSmith provides:

- **Observability** to see exactly how your agent thinks and acts with detailed tracing and aggregate trend metrics.
- **Evaluation** to test and score agent behavior on production data and offline datasets for continuous improvement.
- **Deployment** to ship your agent in one click, using scalable infrastructure built for long-running tasks.

The Google Gemini card is missing the required 'href' attribute that other LLM provider cards have, making it non-functional as a link.
