Project record
Maintained by LangChain Inc.23
LangGraph is an open-source, low-level orchestration framework and runtime for long-running, stateful agents. It is built by LangChain Inc. but can be used without the LangChain library, and a JavaScript/TypeScript version, LangGraph.js, lives in a separate repository. The README credits Pregel and Apache Beam as inspirations.25
