ShipAny Next is a headless SaaS engine: pre-wired business logic with minimal UI. Instead of shipping yet another themed template, it gives you the machinery every SaaS needs — authentication, payments, subscriptions, a credit system, role-based access control, and internationalization — and stays out of the way of your product pages.

Why headless?

Most SaaS boilerplates couple their business logic to a specific landing page design. The moment you rebrand, you fight the template. ShipAny Next splits the codebase along a different line:

• src/components/ — durable primitives. Pricing tables, headers, sidebars, shadcn/ui. These survive a rebrand.

• src/blocks/ — disposable page sections. They read your translations and wire content into the primitives. Rewrite them per project.

• src/modules/ — pure business logic. Payments, credits, subscriptions, RBAC. Each module is a standalone service file you can delete without breaking the others.

What's in the box

1. Authentication — email/password and OAuth via better-auth, with session management and account linking.

2. Payments — Stripe, PayPal, and Creem providers behind a single PaymentManager interface.

3. Credits — FIFO consumption, expiration, auto-grant on signup, and revocation for usage-based billing.

4. RBAC — roles and permissions with wildcard matching, plus a full admin panel.

5. Multi-database — Drizzle ORM with PostgreSQL, MySQL, SQLite, Turso, and Cloudflare D1 support.

6. i18n — English and Chinese built in, locale-aware routing via next-intl.

Getting started

pnpm install
cp .env.example .env.development
pnpm db:push
pnpm dev

That's it — the engine runs on SQLite out of the box, and you can switch databases by changing one env var. Build your product on top, not the plumbing underneath.
