🔧 The Problem

You want to launch a SaaS but spend weeks setting up your stack:

  • Landing page (Next.js or Astro?)
  • Auth (NextAuth? Clerk? DIY with Supabase?)
  • Blog (Markdown? CMS? Skip it?)
  • Dashboard (Tailwind + React or prebuilt templates?)
  • Stripe integration (huge pain)

The result? You never ship. Or worse — you burn out.

⚡ The Solution: Hybrid Stack with Astro + Next.js

Let’s stop overthinking and use a hybrid stack:

  • ⚡ AstroJS → Lightning-fast landing page + blog
  • 🔐 Next.js + NextAuth.js → Secure auth + dashboard
  • 💳 Stripe → Quick monetization
  • 🧩 One codebase, split by function: Static vs Dynamic

Yes, you can use Astro and Next.js in the same SaaS (thanks to subdomains or Vercel rewrites).

🧪 Step-by-Step Setup

1. 🛠 Set Up the Project Folders 

mkdir saas-stack
cd saas-stack
pnpm create astro@latest landing
pnpm create next-app@latest app
Enter fullscreen mode Exit fullscreen mode

Use Astro for landing/ and Next.js for app/.

2. 🌐 Subdomain Setup (Optional but Clean)

Use:

  • app.mysaas.com → for the Next.js app
  • www.mysaas.com → for the Astro marketing site

Set up subdomains on Vercel, Cloudflare Pages, or Netlify + Render.

3. 🎨 Astro Marketing Site

Use an Astro theme like:

Add blog support:

pnpm astro add mdx
Enter fullscreen mode Exit fullscreen mode

Write blogs in /content/blog/*.mdx for SEO boost!

4. 🔒 Next.js Auth + Dashboard

Inside app/ folder:

  • Install NextAuth: 
pnpm add next-auth
Enter fullscreen mode Exit fullscreen mode
  • Setup pages/api/auth/[...nextauth].ts
  • Use GitHub or email/password auth
  • Protect routes with: 
import { useSession } from 'next-auth/react';
Enter fullscreen mode Exit fullscreen mode

Use Tailwind UI or shadcn/ui to scaffold a basic dashboard.

5. 💸 Stripe Integration

Quick-start:

pnpm add stripe
Enter fullscreen mode Exit fullscreen mode
  • Use Stripe’s SaaS starter for inspiration
  • Handle billing in Next.js (/billing page)
  • Use webhooks via api/stripe/webhook.ts

Use Astro for speed and SEO.
