Overview
A full-featured Next.js 16 SaaS starter with auth, payments, email, and AI wired in.
The Next.js template is a full-featured SaaS starter built on Next.js 16 and the App Router. It ships with authentication, a PostgreSQL database, payments, transactional email, internationalized content, and AI features already wired together so you can focus on your product instead of plumbing.
Auth, database, email, and content/i18n are integrated end to end. A few surfaces — the newsletter and parts of the dashboard — are working examples or UI starters you'll adapt to your product before launch. The feature status table below spells out each one.

Feature status
Throughout these docs, features are labelled consistently:
- Integrated — connected end to end in the template.
- Example — a working reference implementation that still needs product-specific policy, limits, or data.
- UI starter — a designed surface backed by mock/static data or unfinished actions.
| Area | Status | Scope |
|---|---|---|
| Authentication | Integrated | Email/password, verification, reset, GitHub/Google OAuth, sessions, admin plugin |
| Database | Integrated | PostgreSQL pool, Drizzle schema, auth and payment tables |
| Payments | Example | Creem checkout, query, signature verification, and selected webhook events |
| Email / contact | Integrated | Resend delivery for auth and contact messages |
| Newsletter | UI starter | Email template only; no subscription route or persistence |
| AI | Example | OpenAI chat streaming and Replicate media task flows |
| Content & i18n | Integrated | Fumadocs docs, blog/legal collections, English and Chinese routing |
| Dashboard / admin | UI starter | Several pages use static/mock data; admin API has a server-side role guard |
| Storage | Example | Authenticated image upload to local public/uploads; replace for hosted production |
