Replay any workflow execution step-by-step. Inspect the full state at every node, compare runs, and debug agent behavior with complete visibility.

Time-Travel Debugging

Key Capabilities

Execution Replay

Replay any workflow run from start to finish. Step forward and backward through each node, seeing inputs, outputs, and timing at every stage.

State Snapshots

Every step captures a full state snapshot - model inputs, raw responses, transformed outputs, and metadata. Nothing is lost.

Step-by-Step Debugging

Pause on any step to inspect the complete context. See the exact prompt sent to the LLM, the raw response, and how it was processed by downstream nodes.

Run Comparison

Compare two runs side-by-side to understand what changed. Identify regressions, debug non-deterministic behavior, and validate prompt changes.

Every run, fully visible

The Runs dashboard shows every workflow execution with status, duration, cost, and timestamp. Filter by completed, failed, or running. Search by workflow name. Click any run to drill into the step-by-step execution timeline with full state inspection at every node.
