How I Built a $0 SaaS That Gets 1000 Users/Month

The Dream

Build a SaaS product without spending a dime. Here's how I did it.

The Stack (All Free)

Service	Purpose	Free Tier
Vercel	Frontend hosting	Unlimited
Supabase	Database	500MB
MonkeyCode	AI coding	Free tier
Cloudflare	CDN/Security	Unlimited

The Process

Week 1: Planning

• Used MonkeyCode to generate the architecture
• Designed the database schema with Supabase
• Set up the project structure

Week 2: Development

• Built the frontend with Next.js
• Integrated Supabase for authentication
• Added AI features using MonkeyCode

Week 3: Launch

• Deployed to Vercel
• Set up Cloudflare for security
• Launched on Product Hunt

The Results

Metric	Month 1	Month 2	Month 3
Users	100	500	1000
Revenue	$0	$50	$200
Cost	$0	$0	$0

Key Lessons

1. Start simple — MVP first, features later
2. Use free tools — No need to pay for everything
3. AI is your friend — MonkeyCode saved me weeks of coding
4. Launch early — Get feedback fast

The Code

// AI-generated API endpoint
export async function POST(req) {
  const { email, name } = await req.json();

  const { data, error } = await supabase
    .from('users')
    .insert([{ email, name }]);

  if (error) return NextResponse.json({ error }, { status: 400 });
  return NextResponse.json({ data });
}
