Run replay

Re-run a past execution with the same input.

The run inspector#

Open a run and pick a node to see its Input, Output and timing. This is the fastest way to understand what a workflow actually did versus what you expected.

The live trace#

For agent nodes, a Trace tab shows every tool call as it happens — arguments, result, duration — flipping from running to success/failed in place, no page refresh.

Rerun & replay#

Click Rerun (or POST /api/v1/executions/{id}/rerun) to replay the workflow with the original input. Perfect for verifying a fix against the exact case that failed.

Resume paused runs#

Runs paused on a human-approval step resume when the approver acts — or via POST /api/v1/executions/{id}/resume with the one-time token.
