Build Your MVP This Weekend for $0 on AWS

Everything I shared at AWS Community Day Cebu about shipping real products on the free tier. No surprise bills, just smart architecture choices.

Ship a real MVP this weekend without the surprise bills

I gave this talk at AWS Community Day Cebu on September 13, 2025. The event theme was "Build Beyond Limits" and it was held at UP Cebu Performing Arts Hall. This post covers everything from that session so you can follow along at your own pace.

The Problem We All Face

You've got an idea. You want to build it. But then you start thinking about cloud costs and suddenly you're paralyzed.

What if I rack up a massive bill? What if I pick the wrong architecture? What if, what if, what if...

And the idea just sits there. Unbuilt. Forever.

Sound familiar? Yeah, me too.

The Good News

You can build and deploy a real, working MVP in one weekend. With authentication, a database, file storage, analytics, the whole package. And it'll cost you somewhere between $0 and $5.

This isn't about cutting corners or building something janky. It's about being smart with your architecture choices. AWS Free Tier is genuinely generous if you know how to use it.

What You'll Learn

The MVP Mindset

Start small: serverless and managed services are your friends
Ship fast: perfect is the enemy of done
Track costs: set up billing alerts before you build anything
Iterate: real user feedback beats imaginary perfect features

What We're Building

A QR Code Generator app. Sounds simple, but it covers all the bases:

User authentication with Amazon Cognito
Database storage with DynamoDB
File storage with S3
Serverless APIs with Lambda
Analytics and tracking
Production deployment with Amplify

Why This Works

The traditional approach looks like this: spend weeks on perfect architecture, write perfect code, build all the features, never actually ship.

The MVP approach: pick a good enough architecture, write working code, build one feature really well, ship it, then iterate based on what real users tell you.

The Architecture

Why Serverless for MVPs?

Serverless is perfect for MVPs because you only pay for what you use. No traffic? No bill. Suddenly go viral? It scales automatically. You don't have to babysit servers, and monitoring comes built in.

Focus on building features, not managing infrastructure.

Weekend Timeline

Here's roughly how your weekend could look:

Saturday Morning (2 hours)

Set up your AWS account and immediately configure billing alerts (seriously, do this first). Bootstrap a Next.js app, deploy it to Amplify, and wire up authentication with Cognito.

Saturday Afternoon (4 hours)

Design your database schema in DynamoDB, build out the core QR generation feature, and throw together a basic UI.

Sunday (3 hours)

Polish everything, test it properly, deploy to production, and share it with your first users.

That's about 9 hours total, and you'll stay well within the free tier.

AWS Free Tier Limits

Here's what you get for free every month:

Service	Free Limit	Duration	Use Case
Lambda	1M requests/month	Always free	Your API endpoints
DynamoDB	25GB storage	Always free	All your user data
S3	5GB storage	12 months	File uploads
Cognito	10K monthly users	Always free	Authentication
API Gateway	1M calls/month	12 months	REST APIs
CloudFront	1TB transfer/month	Always free	CDN for your assets
Amplify	5GB hosting + builds	Always free	Deploy and host

Note: Cognito's free tier changed in late 2024. New user pools created after November 2024 get 10K MAU free (down from 50K for older pools). S3 and API Gateway free tiers expire after your first 12 months, so keep that in mind for longer-running projects.

These limits can comfortably handle 1000+ active users in your first months. By the time you outgrow them, you'll hopefully have revenue to cover the costs.

The QR Code Generator

What exactly are we building? A real SaaS app with:

MVP Features

User registration and login
Generate QR codes with custom URLs
Dashboard showing your QR code history
Track when your codes get scanned
Download QR images

What We're NOT Building (Yet)

Fancy analytics dashboard
Team collaboration
Custom QR designs with logos
Bulk operations
Developer API

Why such a narrow scope? Because one feature done really well beats ten features done halfway. You can always add more later once real users tell you what they actually want.

Cost Control (Super Important)

Set Billing Alerts FIRST

Before you do anything else, set up billing alerts. Seriously. Do this first.

aws budgets create-budget \
    --account-id $(aws sts get-caller-identity --query Account --output text) \
    --budget '{
        "BudgetName": "Weekend MVP Budget",
        "BudgetLimit": {"Amount": "10", "Unit": "USD"},
        "TimeUnit": "MONTHLY",
        "BudgetType": "COST"
    }'

Keep an Eye on Things

Check your AWS bill weekly. If you hit 80% of your budget, start optimizing. If you see unusual spikes, investigate immediately. Don't wait for a surprise bill.

As You Grow

Starting out ($0/month): Free tier handles 100 to 1000 users just fine
Getting serious ($5 to $20/month): Add a custom domain, email
Growing fast ($20 to $100/month): Time to scale up features

Success Metrics

How do you know if your MVP is actually working?

Technical Stuff

App loads in under 2 seconds
QR codes generate in under 5 seconds
99%+ uptime (serverless makes this pretty easy)
Works on mobile

Business Stuff

10 users in your first week
50 QR codes generated
100 scans recorded
At least 1 person gives you feedback (this is gold)

Cost Stuff

Stay under $5/month
Check your spending regularly
Optimize before you need to scale

Implementation Details

Pick Managed Services

Let AWS handle the infrastructure so you can focus on your actual product:

const smartChoice = {
  database: 'DynamoDB',
  auth: 'Amazon Cognito',
  storage: 'S3',
  api: 'API Gateway + Lambda',
  hosting: 'Amplify',
}

Don't do this to yourself:

const painfulChoice = {
  database: 'PostgreSQL on EC2',
  auth: 'Custom JWT implementation',
  storage: 'EC2 file system',
  api: 'Express server on EC2',
  hosting: 'Custom nginx setup',
}

You'll spend all your time managing servers instead of building features.

Database Design

type QrItem @model @auth(rules: [{ allow: owner }]) {
  id: ID!
  targetUrl: String!
  s3Key: String!
  createdAt: AWSDateTime!
  scanCount: Int @default(value: 0)
}

type QrScan @model @auth(rules: [{ allow: public, provider: apiKey }]) {
  id: ID!
  qrId: String! @index
  scanAt: AWSDateTime!
  userAgent: String
}

Simple, and it respects user privacy. That's all you need to start.

What You'll Have by Sunday

By the time you close your laptop Sunday evening, you'll have:

A Real Product

Working auth system
Database with real data
File storage with CDN
Analytics and tracking
Mobile responsive UI
Live in production

Actual Skills

AWS Amplify development
Serverless architecture patterns
React/Next.js best practices
Database design
Cost monitoring

A Foundation to Grow

Modern architecture that scales
Industry standard tech stack
Something real for your portfolio
Real users giving real feedback

Ready to Build?

Don't let this become another tutorial you bookmark and forget. Pick a weekend and actually ship something.

Key Takeaways

Start small: one feature done well beats ten done poorly
Ship fast: real feedback beats perfect features every time
Use managed services so you can focus on your product instead of infrastructure
Set billing alerts before you create anything
Build, ship, get feedback, repeat

The best time to ship was last weekend. The second best time is this weekend.

Community: AWS Amplify Discord

Huge thanks to AWS User Group Cebu for having me, to all the volunteers who made the event happen, and to everyone who showed up. The energy at UP Cebu was incredible. And if you're hesitant about starting small, remember that every iteration gets you closer to something real.
