The complete guide to building and selling a Micro-SaaS boilerplate for $99

The indie hacker dream has shifted. It used to be about building a massive B2C app that goes viral. Today, the most reliable path to independent income is building a Micro-SaaS, and increasingly, building the picks and shovels for other developers.

Over the last year, "boilerplates" have exploded in popularity. Why? Because developers realize their time is worth more than grinding through Stripe documentation for the fifth time.

I recently launched my own AI SaaS Boilerplate, and in this guide, I'm going to break down exactly how you can build, package, and sell your own technical product.

Why Boilerplates Work

A boilerplate solves a very specific, high-pain problem: The Setup Phase.

Every time a developer has an idea for a SaaS, they face a wall of chores:

• Setting up Next.js / React
• Configuring Tailwind CSS
• Integrating authentication (NextAuth, Supabase, Clerk, etc.)
• Setting up a database schema and ORM (Prisma, Drizzle)
• Implementing payment webhooks (Stripe, LemonSqueezy)
• Writing transactional emails

This takes days, sometimes weeks. If you can package this into a single, well-documented repository, developers will gladly pay you $50-$200 to skip that line. It’s a pure ROI calculation.

Step 1: The Tech Stack (Choosing your flavor)

You can't build a boilerplate for everyone. You need to pick an opinionated stack. The most popular right now for indie hackers is the "T3-adjacent" stack.

Here is what I recommend bundling:

• Framework: Next.js (App Router)
• Styling: Tailwind CSS + shadcn/ui
• Database: PostgreSQL via Supabase or Vercel Postgres
• ORM: Prisma
• Payments: Stripe
• AI Integration: OpenAI or Google Gemini SDKs

Step 2: The Architecture of a Boilerplate

When you write code for yourself, messy is fine. When you write code for others to consume, it needs to be pristine.

Here’s how you should structure the codebase:

/src
  /app           # Next.js pages and API routes
  /components    # Reusable UI components
    /ui          # Dumb components (buttons, inputs)
    /shared      # Smart components (navbar, footer)
  /lib           # Utility functions
    stripe.ts    # Stripe client setup
    supabase.ts  # Database client setup
    ai.ts        # LLM client setup
  /types         # Global TypeScript interfaces

Crucial tip: Use environment variables extensively. The goal is for the user to clone the repo, run npm install, paste in their .env keys, and have a working app.

Example of a clean Stripe webhook handler included in a boilerplate:

// app/api/webhooks/stripe/route.ts
import { headers } from 'next/headers';
import { stripe } from '@/lib/stripe';
import { db } from '@/lib/db';

export async function POST(req: Request) {
  const body = await req.text();
  const signature = headers().get('Stripe-Signature') as string;

  let event;
  try {
    event = stripe.webhooks.constructEvent(
      body,
      signature,
      process.env.STRIPE_WEBHOOK_SECRET!
    );
  } catch (error) {
    return new Response('Webhook Error', { status: 400 });
  }

  // Handle the event
  if (event.type === 'checkout.session.completed') {
    const session = event.data.object as any;

    // Update user in DB
    await db.user.update({
      where: { stripeCustomerId: session.customer },
      data: { isSubscribed: true, plan: 'PRO' },
    });
  }

  return new Response(null, { status: 200 });
}

This is code developers hate writing. Providing this pre-written is where the value lies.

Step 3: Documentation is the Product

A boilerplate with bad documentation is just a confusing GitHub repo.
You need to provide a step-by-step guide.

Your docs should cover:

1. Local Setup: How to clone and install dependencies.
2. Environment Variables: Exactly where to find every API key (Stripe, Supabase, Google, etc.) with screenshots.
3. Deployment: How to push to Vercel.
4. Customization: How to change the branding, colors, and fonts.

Step 4: Selling It

Platforms like Gumroad or LemonSqueezy are perfect for this. You just zip the repository (or invite them to a private GitHub repo upon purchase) and set a price.

I priced mine at $99. It's expensive enough to signal quality, but cheap enough to be an impulse buy for a developer who values their time at $50+/hour.

The Shortcut

Building a boilerplate is a fantastic project, but it takes months of refining to get right.

If you just want to build your SaaS today, you don't need to build the boilerplate yourself. You can leverage the hundreds of hours I've already spent perfecting one.

I've built the ultimate Next.js boilerplate complete with Supabase Auth, Stripe payments, responsive UI components, and built-in AI API integrations.
