LangChain GitHub

LangChain GitHub — The official GitHub repository — github.com/langchain-ai/langchain — is where the code, examples, and issues for the open-source LangChain framework live. The repository hosts Python and TypeScript packages that wrap large language models, vector stores, and agent tools into a single API. The maintainers push out weekly releases, manage pull requests from thousands of contributors, and publish detailed CHANGELOG entries so developers can pin safe versions. Inside the /docs and /examples folders, you’ll find working notebooks covering Retrieval-Augmented Generation (RAG), chat memory, and agent tool invocation, while GitHub Actions runs unit tests on every commit to keep builds green. Discussions and issues serve as the project’s roadmap, uncovering feature requests and bug fixes in real time. By forking or cloning the LangChain GitHub repository, teams can review code for compliance, submit patches, and track breaking changes—all critical to LLM production pipelines that require transparency and rapid iteration.
