@fayz-ai/saas

Turn plugins into a real multi-tenant SaaS with one defineSaas call.

This is where the Fayz pitch becomes a product. @fayz-ai/saas is the multi-tenant layer that wraps the headless core in everything a commercial app needs: organizations and tenancy, role-based permissions, billing, a native CRUD engine, and a full admin shell. You enable a set of plugins, call defineSaas, and get a running app with auth, org switching, permission gates, and a generated admin UI.

A salon and a clinic ship from the same engine — @fayz-ai/saas is the part that makes each one a real, isolated, billable tenant. Plugins snap in; this layer gives them an org to live in, a user to act as, and a shell to render through.

What's inside

• App factory — defineSaas, createSaasApp, createFayzApp, AdminScaffold, AdminShell, LoginPage (manifest-first admin entry)
• CRUD engine — CrudPage, CrudListView, CrudFormPage, CrudDetailPage, CrudCardGrid, createCrudPage, ImportWizard, exportToCSV
• Org / multi-tenancy — createSupabaseOrgAdapter, createMockOrgAdapter, OrgProvider, useTenant, useOrganizationStore
• Permissions — PermissionsProvider, PermissionGate, usePermission, useHasPermission, usePermissions
• Billing — useBillingStore with Subscription / Invoice types (Stripe-backed)
• Plugin framework UI — WidgetSlot, SettingsGroup, QuickActionsButton, ModuleActionBar, createPluginContext, createViewRouter, PluginRegistryManager
• Supabase + theme — createFayzSupabaseClient, getCoreSchemaClient, createFayzTheme, fayzThemePresets
