Try changes in a private preview with sample data, test the main journeys, and deploy a verified version to its own HTTPS address.\n\nConnect an existing Sprout account or create your first project through email confirmation. You can also update an app, inspect its deployment history, and investigate errors. New apps are private by default; making an app public requires your instruction.\n\nA Sprout account is required for building and managing apps. Available capabilities depend on your account and configured services. Third-party integrations require separate authorization in Sprout. Passwords, API keys, and other secret values are entered directly in Sprout, never in chat.",
