    Sample input

    Add Clerk Organizations to my Next.js 14 app. I need to sync orgs to a local tenants table and handle the webhooks for membership changes.

    Sample output

    I've generated the clerk-multitenant/ suite:

    • webhook-handler.ts: Handles org/membership events with Svix verification.
    • db-sync.sql: Schema for tenants and tenant_memberships tables.
    • middleware.ts: Scopes every DB query by the session's active org_id.
    • OrgSwitcher.tsx: Frontend wrapper for state sync.

    About This Skill

    Enterprise Multi-Tenancy for Clerk Apps

    Transform your Next.js or FastAPI application into a robust multi-tenant SaaS using Clerk Organizations. This skill implements the framework-first integration pattern required to handle organization isolation, role-based access control (RBAC), and database synchronization without reinventing authentication logic.

    What it does

    • Tenant Mapping: Creates a localized mirror of Clerk Organizations in your SQL database, ensuring every domain record is safely scoped to a tenant_id.
    • Webhook Architecture: Deploys a production-ready webhook handler with Svix signature verification to sync org creations, deletions, and membership changes.
    • Request-Level Context: Injects middleware (Next.js) or dependencies (FastAPI) that resolve the active org_id from the Clerk session and apply it to your internal request context.
    • RBAC Synchronization: Maps Clerk's organizational roles (Admin/Member) to your app's internal permission system.
    • Switcher Integration: Provides a React wrapper for the Clerk OrganizationSwitcher that ensures server-side state stays fresh when users switch tenants.

    Why use this skill?

    Manually wiring Clerk Organizations into a database schema is error-prone. This skill prevents common pitfalls like "tenant drift" by enforcing a strict webhook-first synchronization strategy and ensuring that org_id is always resolved from the secure session rather than untrusted client headers.

    Supported Frameworks

    • Next.js: App Router, Middleware, and React Server Components.
    • FastAPI: Dependency injection and ContextVar-based scoping.
    • Databases: PostgreSQL/SQL-ready schemas for tenants and memberships.

    Use Cases

    • Sync Clerk Organizations and memberships to a local PostgreSQL database
    • Enforce per-tenant data isolation in Next.js or FastAPI backends
    • Map Clerk roles (admin/member) to internal application permissions
    • Migrate a single-tenant Clerk app to a multi-org SaaS model
