Choosing the right tech stack for your SaaS can make or break your development speed and long-term maintainability. Here is why Astro + Next.js + Supabase is the ultimate combination.
Astro 6 for the Storefront
Astro delivers near-zero JavaScript by default, resulting in perfect Lighthouse scores. It excels at content-focused pages like landing pages, blogs, and pricing pages. With React 19 integration, you get interactive components only where you need them.
Next.js 15 for the Admin Panel
Next.js 15 provides the full power of React with server actions, streaming, and the App Router. The admin panel needs complex data management, authentication, and real-time updates — areas where Next.js shines.
Supabase for the Backend
Supabase is Firebase on steroids: PostgreSQL database, authentication, storage, real-time subscriptions, and edge functions — all open-source. Drizzle ORM gives you type-safe SQL with full TypeScript support.
Tailwind CSS v4 for Styling
Tailwind CSS v4 brings CSS-first configuration with the @theme directive, making it easy to support dynamic brand colors. shadcn/ui components provide a polished, accessible UI out of the box.
The Result
A SaaS that loads instantly, scales effortlessly, and is a joy to maintain. Your storefront is fast, your admin is powerful, and your backend is rock-solid PostgreSQL.
