This is the Lyraflow demo.

A real install with generated data in it. Everyone who opens it shares one signed-in session, and it rebuilds itself every hour.

What is in it: 1,200 people and 20,000 events over 90 days — a signup-to-purchase funnel, segments, a retention grid, trends and a dashboard, all built from the same generated history.

• Everything you build is gone at the top of the hour, and so is anything anyone else built.
• You are signed in as the same person as everyone else here. Expect to find someone mid-experiment.
• Nothing real belongs in it. Do not send events from anything you care about.
• Deleting a person is refused; everything else you can delete, and the rebuild brings it back.
