Why This Stack

Clerk provides pre-built auth UI components and webhook-driven user sync. Stripe handles subscription billing, invoicing, and the customer portal. Together they cover the "sign up → subscribe → manage" flow without building auth or billing from scratch.

1

Use Clerk webhooks to sync user creation to your database and Stripe customer records

2

Store Stripe customer_id on Clerk user metadata for quick lookups

3

Use Clerk's `<SignedIn>` / `<SignedOut>` components to gate premium features

4

Stripe Checkout sessions can be created in API routes protected by Clerk middleware
