Checkpoint Management With Automatic Saving And Resumption

via “checkpointing and persistence with basecheckpointsaver interface”

Build resilient language agents as graphs.

Unique: Provides a pluggable BaseCheckpointSaver interface with prebuilt implementations (SQLite, PostgreSQL) that automatically persist state after each superstep. Unlike frameworks requiring manual checkpoint logic, LangGraph integrates checkpointing into the execution engine, making persistence transparent and deterministic.

vs others: Eliminates manual checkpoint management code by integrating persistence into the execution engine, and provides stronger recovery guarantees than frameworks relying on external state stores or event logs.
