This is a curated index of the LangChain and LangGraph ecosystem for teams building, observing, evaluating and deploying stateful, tool-using AI agents. It organizes core frameworks such as LangChain, LangGraph, Deep Agents and LangSmith alongside official integrations and MCP tooling for models, vector stores, loaders and tools.

Beyond the official project family, it lists community projects grouped by use case, including web automation and scraping, business intelligence, data science, cybersecurity, retrieval-augmented generation and document processing, and workplace and productivity agents. It also links starter templates and learning resources aimed at getting a new agent project running quickly.

The list is maintained as a GitHub repository and accepts community contributions.
