Product Demo Environment Generator

 Build a Product Demo Environment Generator that creates realistic, isolated demo environments for SaaS applications. Let users define customer personas, sample organizations, user roles, products, transactions, and complete demonstration scenarios. Generate coherent synthetic data that makes the product feel actively used without exposing real customer information. Include one-click reset, scenario switching, seeded error states, guided demo journeys, and environment-expiration rules. Provide adapters for database seeding and application APIs, with dry-run previews, explicit environment boundaries, and cleanup safeguards. The system must never copy production personal data into a demo environment by default.
