Every SaaS starts with the same two weeks of plumbing: authentication, a database, payments, email, a dashboard, settings, an admin view. NextStarter Pro is that plumbing — done properly, typed, tested, and ready to build on — so you can spend your time on the product, not the boilerplate.

Built on Next.js 16 (App Router), TypeScript (strict), and Tailwind CSS v4.

What's included

Core app

• 🔐 Authentication (Clerk) — sign-in, protected routes, user profile
• 🗄️ Database (Prisma + PostgreSQL) — a real user-owned CRUD example
• 💳 Billing (Stripe) — subscriptions, Checkout, and the customer portal
• ✉️ Email (Resend + React Email) — transactional email with templates
• 📊 Dashboard app shell — sidebar, responsive drawer, protected pages
• 🛡️ Admin panel — metrics + a searchable user table

Growth & polish

• 🌍 Internationalization (next-intl) — English, Spanish, and Arabic (RTL)
• 📝 MDX blog + a validated contact form (React Hook Form + Zod)
• 🚀 Waitlist / launch mode for pre-launch email capture
• 📈 Analytics (PostHog, cookieless) + error tracking (Sentry)
• 🔒 Security — CSP + hardening headers, API rate limiting, input sanitization
• 🔎 SEO — auto sitemap/robots, Open Graph, per-page metadata, hreflang

Developer experience

• ✅ Accessibility, verified — WCAG 2.1 AA, scanned with Axe-core in light and dark mode on every test run
• 🧪 Tested — Playwright across Chromium, Firefox & WebKit, plus Vitest units
• 📚 Comprehensive docs — setup, per-integration guides, and deployment
• ⚙️ Optional-by-env — the app builds, runs, and passes CI with zero keys; add a key to turn each integration on

Why NextStarter Pro

Accessibility isn't a checkbox here — it's tested. Most boilerplates ignore it entirely. NextStarter verifies WCAG 2.1 AA with automated Axe-core scans in both themes, which matters for government, enterprise, and agency work where compliance is a requirement, not a nice-to-have.

Everything is optional by design. No key? The feature shows a tidy "not configured" notice and the app still builds and ships. Turn things on when you're ready — no half-broken states, no ripping code out.

What you get

• Repository access — after purchase, connect your GitHub account from the customer portal and you're invited to the private repository automatically.
• Lifetime updates — pull new features and fixes with git pull; the CHANGELOG and GitHub Releases track every change.
• Use it on unlimited personal and commercial projects (single-developer license).

Requirements

Node.js 22+ and a GitHub account. Everything else (Clerk, Stripe, Supabase, Resend, PostHog, Sentry) is optional and has a generous free tier.
