Code With Antonio → interactive architecture
One run. One browser session. One coherent replay.
This lab turns the workflow-observability architecture from Antonio’s Browserbase agent tutorial into something you can manipulate. Change the session strategy, status flushing, and failure state to see what remains observable.

Transcript-grounded evidence
Why these controls exist.
Each lever corresponds to a design decision Antonio explains in the tutorial. Open the timestamp to hear the source in context.
Reuse one session
The run lazily opens Stagehand once and passes it through every executor, preserving state until the workflow closes.
Flush state transitions
Running and failed metadata must be flushed before later state or a thrown run prevents it from reaching the canvas.
Replay the whole workflow
Browserbase observability supplies one end-to-end session replay, rather than a separate recording for each step.
