# LangChain ecosystem

Apify integrates with the LangChain ecosystem in two places: LangChain itself, for loading web data and calling Actors as tools, and LangGraph, for stateful, multi-agent workflows. Both ship in the same [langchain-apify](https://github.com/apify/langchain-apify) package, so one install covers both.

## What you can build

Both pages cover the same package. Pick the one that matches how you want to call Actors:
