Actual results from Serverless Startup Journey
Cost Analysis: Bootstrapper’s Advantage
Traditional Stack: Like renting an entire kitchen when you only need a blender
Serverless Stack: Paying only for each smoothie you actually make
Typical MVP Monthly Costs
- Vercel: Free – $20 (Hobby plan)
- Supabase: Free – $25 (Pro plan)
- Stripe: 2.9% + 30¢ per transaction
- Total: $0-$45 + transaction fees
Compare with traditional alternatives:

Real-time Dashboard Example
const subscription = supabase
.from(‘payments’)
.on(‘INSERT’, payment => {
// Update dashboard in real-time
updateRevenueChart(payment.amount)
})
.subscribe()
Stripe Webhooks with Vercel
export default async (req, res) => {
const sig = req.headers[‘stripe-signature’];
const event = stripe.webhooks.constructEvent(
req.body,
sig,
process.env.STRIPE_WEBHOOK_SECRET
);
// Handle subscription events
switch(event.type) {
case ‘invoice.paid’:
await handleInvoicePaid(event.data.object);
break;
// Other event types
}
res.status(200).end();
};
