About this project

Awesome LangChain is a community-maintained directory of resources built around the LangChain framework for LLM application development. It organizes hundreds of projects into practical categories: official LangChain libraries (Python, JavaScript) and unofficial ports for Go, Ruby, Java, Dart, Haskell, Elixir, and Rust; low-code visual builders like Flowise, Langflow, and Flock; services for caching (GPTCache), evaluation, observability (LangWatch, OpenLLMetry), and deployment (Chainlit, Dify); autonomous agent frameworks such as CrewAI, SuperAGI, AutoGPT variants, and LangChain's own deepagents; starter templates for Vercel, T3, Streamlit, Gradio, and Codespaces; and open-source applications spanning knowledge management (Quivr, DocsGPT, AnythingLLM), document chat, code assistants, and specialized bots. The list also links to learning materials (notebooks, video playlists) and alternative LLM frameworks. It serves as a discovery hub for developers building with LangChain, helping them find ready-made components, reference architectures, and production-ready tools.
