nextjs saas starter

• For a product launch page, compare messaging sections, pricing presentation, documentation and lead capture. Verify where submitted forms go; a styled form can still have no working backend.
• For a subscription application, inspect account creation, server-side authorization, payment webhooks and data ownership. A pricing card or checkout button is not evidence that subscription state is synchronized.
• List required third-party services and their configuration before adopting a starter. Test failed payments, cancelled accounts and unauthorized requests in an isolated environment. Treat functionality marked unknown in this catalog as something to investigate, not as included functionality.

First six results in catalog order, not a ranking. Listed features come from repository records and still need verification.
