LangChain - a Framework to Build Intelligent LLM Apps

What is LangChain?

LangChain is a comprehensive framework designed for the development of applications powered by large language models (LLMs). It simplifies the entire application lifecycle, offering numerous benefits for developers.


One of the primary advantages of LangChain is its open-source libraries. Developers can leverage LangChain's open-source building blocks, components, and third-party integrations to build their applications. LangGraph, a part of LangChain, supports the creation of stateful agents with first-class streaming and human-in-the-loop capabilities. These features allow developers to maintain real-time interactions and user involvement in their applications.

Complete LLM Apps Development Cycle

The LangChain framework is also beneficial when it comes to productionizing your apps. Using LangSmith, developers can inspect, monitor, and evaluate their apps, enabling them to optimize and deploy these applications with confidence. This ensures that your apps are always performing at their best, and any potential issues can be identified and addressed promptly.

Simple Deployment Process

Furthermore, LangChain aids in the deployment process. With LangGraph Cloud, developers can easily convert their LangGraph applications into production-ready APIs and Assistants. This not only streamlines the process of getting your applications to market but also ensures that they are equipped to handle real-world demands.

In conclusion, LangChain is an all-encompassing framework that supports developers throughout the lifecycle of their applications. By utilizing its open-source libraries, productionization tools, and deployment capabilities, developers can create, optimize, and launch applications with efficiency and confidence.


LangChain is written using Python, and Jupyter Notebook.
