Langchain
LangChain’s suite of products supports AI development
LangChain is an open-source framework for building applications that use language models. It streamlines connecting LLMs to external data sources, APIs, and custom logic, providing components such as chains, agents, memory, and retrieval‑augmented generation. The library supports databases, vector stores, and a range of tools, enabling developers to create chatbots, document analysis systems, search services, and automation workflows while maintaining flexibility and avoiding vendor lock‑in.
