System Documentation

What problem does it solve?

Time travel in LangGraph enables debugging and auditing agent decisions by letting you inspect past states, replay execution from checkpoints, fork execution paths, and diagnose issues with historical state.

Core Features & Use Cases

  • Inspect decision points and execution history using get_state_history
  • Replay execution from a checkpoint with optional new input
  • Fork threads/state at checkpoints to explore alternate paths
  • Update state before replay to test recovery or adjustments
  • Diagnose errors by inspecting checkpoints, metadata, and state transitions

Quick Start

Create a MemorySaver checkpointer, compile the graph, invoke with a thread_id, then inspect the state history to understand decision points.
