What does supastack's Next.js app include?
It depends on the plan, but every license ships the same complete Next.js 16 app: sign-in with OAuth, passkeys and two-factor, team workspaces, billing across eight payment providers, AI chat with per-workspace budgets, an admin surface, and 13 languages. The single-platform license covers Next.js alone; the bundle adds the TanStack Start, Expo and Tauri apps on the same backend.
Everything a SaaS needs, already built
The Next.js app is the complete supastack product: the same dashboard, settings, and admin surface buyers see in the demo. You are not assembling a landing page, you are deleting the parts of a finished product you do not need.
- Sign-in with Google, Apple, GitHub, and email magic links, plus passkeys, two-factor, and session management
- Workspaces, roles, and team invitations with per-member permissions
- Billing with checkout, customer portal, and signed webhooks, Stripe, Paddle, Polar, Lemon Squeezy, Dodo, Creem, Whop, and PayPal
- AI chat and background agent tasks with per-workspace budgets and token-usage tracking
- Notifications, activity feeds, a feedback inbox, and a mail preview for every transactional email
- Admin surface with analytics, search, members, and security sessions
- 13 languages, 20+ theme packs, and a full OpenAPI-documented API
- Seed data, real tests, and guides that cover setup through deploy
Built the way Next.js teams expect
The app runs on Next.js 16 with the App Router: React Server Components for fast first paint, route handlers for API endpoints, and streaming where it matters. Everything is typed end to end inside a Turbo monorepo you can navigate in one sitting.
Product logic lives in shared packages, auth, database schema, email, jobs, billing, and AI providers, so the framework layer stays thin. Swapping a provider or reading how webhooks settle takes minutes, not archaeology.
- Next.js 16 App Router + React 19
- React Server Components (RSC) + Server Actions
- TypeScript + Turborepo
- Better Auth
- Drizzle + PostgreSQL
- Trigger.dev
- Sentry + PostHog
From clone to production
Clone, fill in the environment variables, run the migrations, and the app boots with seed data you can click through immediately. The five-minute quickstart walks the exact path, and provider guides cover each integration you switch on.
- One install and one dev command, the first run seeds a demo workspace
- Deploy to Vercel, Docker, Node, or Cloudflare Workers
- Optional providers stay off until you add keys, nothing crashes on a missing secret
