LangChain ecosystem

Copy for LLM

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 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:

LangChain

Wrap Apify Actors as LangChain tools, load crawled pages into a vector index, and retrieve documents for RAG.

LangGraph

Bind Apify tools to stateful, multi-agent LangGraph workflows and stream an agent's steps as it works.
