How I built a production-ready SaaS landing page template with Next.js 14

Every time I started a new SaaS project, I found myself rebuilding the same landing page from scratch. Navbar, hero, features, pricing, testimonials — the same structure, every time.

So I decided to build it once, properly, and make it reusable.

This is what I learned.

The goals

Zero extra dependencies — just Next.js 14, TypeScript and CSS Modules
One config file — all content editable in a single config.ts, no touching components
Premium design — dark mode, Stripe/Linear aesthetic, nothing generic
Deploy-ready — works on Vercel out of the box

Stack decisions

Why CSS Modules over Tailwind?

Tailwind is great, but for a template you're selling, CSS Modules are cleaner. The buyer doesn't need to install or configure anything extra. The styles are scoped, explicit, and easy to override.

Why a single config file?

The biggest friction for template buyers is figuring out where to change things. With a single src/lib/config.ts, the answer is always the same:

export const siteConfig = {
  name: 'YourApp',
  tagline: 'Your tagline here',
  features: [
    { icon: '⚡', title: 'Feature 1', description: '...' },
    // ...
  ],
  pricing: [...],
  testimonials: [...],
}

Change the file, the whole site updates. No hunting through components.

The dashboard preview in the hero

The most impactful design decision was putting a fake dashboard mockup in the hero section instead of a generic screenshot or illustration.

SaaS buyers respond to dashboards — it shows them exactly what kind of product the template is built for, and it looks premium without requiring real data.

The entire dashboard is pure HTML/CSS — no canvas, no charts library.

Sections included

Lessons learned

Design systems in CSS variables pay off. Having all colors in :root meant I could change the entire palette in 3 lines.

Animation delay on hero elements feels premium. Staggered animation-delay on each hero child gives a polished fade-up entrance that costs almost nothing to implement.

The config file is the product. Buyers don't care about the components — they care about how fast they can make it theirs.
