What Is LangGraph? LangGraph 是什么？
LangGraph is an open-source project with 35k+ GitHub stars. Build stateful multi-actor LLM applications as graphs
The project focuses on agent, graph, stateful use cases and operates as an autonomous system that can plan and execute multi-step tasks with minimal human intervention.
Source code is available at github.com/langchain-ai/langgraph. With 35k+ GitHub stars, it ranks among the most battle-tested open-source tools in this space—meaning most common use cases are well-documented with community solutions available.
LangGraph has found solid traction with 10k+ GitHub stars, indicating real-world adoption beyond early adopters. A useful framework for automating multi-step tasks that would otherwise require manual coordination. Set realistic expectations: autonomous agents work well on well-defined tasks with clear success criteria, and struggle with ambiguous goals. Always run with budget limits set.
