LangGraph

WHEN: Building stateful agent orchestration with explicit graph nodes, durable execution, checkpointing, interrupts, subgraphs, or LangSmith-observed agent workflows.

When to Use

• Building multi-step agents with explicit state transitions
• Implementing durable, resumable workflows for long-running tasks
• Adding human approval or interruption points into agent execution
• Modeling branching, loops, retries, and subgraphs explicitly
• Using LangSmith to inspect trajectories, state changes, and failures
