LangGraph solves a specific problem that plain LangChain chains do not handle well: cyclic, stateful workflows where agents revisit steps, branch conditionally, or require human approval mid-run. Confidence is docs-derived.
The API surface centers on graphs with nodes (functions) and edges (routing). State is first-class and persists across steps, which enables real multi-turn agent loops rather than single-pass chains.
Access is open-source library with optional LangGraph Cloud for hosted persistence and deployment. LangSmith API key needed for tracing integration. No separate auth for the core library.
Operationally, graph-based orchestration adds conceptual overhead compared with simple chains, but it also surfaces control and observability that flat pipelines lack. Loop safety (max iterations) needs explicit configuration.
Documentation is thorough and improving rapidly. LangGraph is actively developed alongside LangChain, and the conceptual guides for agent patterns are some of the best available for production agent systems.
