Breakpoints¶
Breakpoints pause graph execution at defined points and let you step through each stage. They use LangGraph's persistence layer, which saves the graph state after each step.
With breakpoints, you can inspect the graph's state and node inputs at any point. Execution pauses indefinitely until you resume, as the checkpointer preserves the state.
Tip
For information on how to use breakpoints, see Set breakpoints and Set breakpoints using Server API.
