What it is
LangGraph is an open-source library from LangChain for building stateful, multi-step agents as graphs. It is a framework you embed in your own app. LangChain also sells hosted products such as LangSmith; those are separate from the library.
The LangGraph library is free to use. Hosted LangChain products have their own plans. Confirm the library license in the repository.
Why it ranks
- Library for custom agent runtimes
- Open source
- Fits when a visual automation tool is not enough
Watch outs
- You are building a product, not turning on a setting
- Hosted observability and deployment are separate purchases
