LangChain is a company that builds software frameworks to help developers create applications powered by large language models. Its flagship products include the open-source LangChain framework, LangGraph for building agent workflows, and LangSmith for monitoring the development process. The LangChain framework itself is open-source and free to use, while LangSmith is a separate product sold as a paid subscription, so the two should not be confused.
