Journey SDK turns real user flows into replayable Python steps. Agents can run the exact step they are changing over and over, inspect browser/email/webhook evidence, then verify the branch or full journey before finishing.
A coding agent develops one meaningful step, reruns only that step after each edit, inspects evidence, then broadens to branch and full-journey verification.
Agent starts from installed Journey guidance instead of inventing a test shape.
One command gives the agent every loop primitive it needs.
The agent uses the first executable failure as the target.
Run just the late step. State is durable.
Agents can iterate this one step repeatedly.
Artifacts, logs, recordings, and payloads prove the journey worked.
Run the whole journey and its branches from a fresh path.
Start with one prompt. Journey turns it into a durable verification loop.
Off-the-shelf resources for side effects agents otherwise struggle to verify: browser traces, Docker logs, hosted email, hosted webhooks, and more touchpoints over time.
Use today for end-to-end verification.
Dedicated inboxes your app can email. Agents can wait for, read, and assert messages.
Stable, secure endpoints that capture events from your system in real time.
