LangGraph
LangChain · Python / TypeScript · MIT
LangGraph models an agent as a stateful graph of nodes and edges, which makes it the go-to choice when a workflow needs persistence, rollback, and human approval gates.
Best for
Complex production agents that need audit trails, checkpoints, and human approval steps.
Strengths
- +Explicit state graph maps to real workflows
- +Checkpointing and human-in-the-loop are first-class
- +Largest integration ecosystem via LangChain
Watch out for
Steepest learning curve here; the graph API is verbose for simple linear tasks.
