SaaS Scaffolder

Generate a complete, production-ready SaaS application boilerplate including authentication (NextAuth, Clerk, or Supabase Auth), database schemas with multi-tenancy, billing integration (Stripe or Lemon Squeezy), API routes with validation, dashboard UI with shadcn/ui, and deployment configuration. Produces a working application from a product specification in under 30 minutes.

Core Capabilities

• Spec-driven scaffolding — produce a full Next.js App Router + TypeScript + Tailwind + shadcn/ui file tree from a short product spec (auth/db/payments/tenancy/features).
• Multi-tenant database schema — Drizzle ORM schema with workspaces (tenancy boundary), users, members, OAuth accounts, and sessions, with proper indexes and cascade rules.
• Authentication — NextAuth v5 with Drizzle adapter, OAuth (Google/GitHub) and magic-link (Resend) providers, route-protection middleware.
• Stripe billing — checkout session, customer portal, and signature-verified webhook handler keeping subscription state in sync.
• Multi-tenancy patterns — workspace-scoped queries and plan-based feature gating (free/pro/enterprise).
• Phased build + quality bar — 5 ordered scaffolding phases with per-phase validation, pitfalls, best practices, troubleshooting, and success criteria.
