AWS Free Tier Guide: How to Host Full-Stack Projects Without Unexpected Bills
To host full-stack projects completely free on AWS without surprise bills: (1) configure AWS Budgets with zero-dollar email alerts immediately upon account creation, (2) host static frontends on S3 + CloudFront (1TB free data transfer monthly), (3) run backend microservices on an EC2 t2.micro / t3.micro (750 free hours/month), and (4) avoid unattached Elastic IPs, NAT Gateways, and multi-AZ deployments which trigger automatic hourly billing.
Every developer has heard the horror stories: a software engineer creates an AWS account for learning, forgets to delete an unattached Elastic IP or provisioned NAT Gateway, and wakes up to an unexpected $400 cloud bill.
The AWS Free Tier is genuinely generous — providing enough compute, bandwidth, and storage to host multiple production portfolio projects, API backends, and static web apps at zero financial cost. The key is understanding exactly which services are 100% free and configuring ironclad guardrails before provisioning resources.
01. Step 1: Setting Up Mandatory Zero-Dollar Billing Alerts
Before launching a single EC2 instance or S3 bucket, configure billing threshold alerts:
- Log into the AWS Management Console → Navigate to Billing and Cost Management.
- Click Budgets → Create budget → Select Zero spend budget.
- Enter your primary email address. AWS will notify you the moment your account incurs as little as $0.01 in charges.
- Create a secondary budget with a strict $5.00 threshold with email and SMS notifications.
02. The Best 100% Free Hosting Stack on AWS
Here is the architectural blueprint to run a modern full-stack web application completely within the free tier limits:
A. Frontend Web Client: Amazon S3 + CloudFront
Instead of running an expensive web server for React, Next.js static export, or Vue apps, upload your built static assets (HTML/CSS/JS) to an Amazon S3 bucket and deliver it via Amazon CloudFront CDN:
- S3 Free Tier: 5 GB standard storage, 20,000 GET requests per month.
- CloudFront Free Tier: 1 TB (1,000 GB) of data transfer out per month, forever free!
- Free SSL: Free wildcard HTTPS certificates issued through AWS Certificate Manager (ACM).
To configure this securely with private S3 buckets and Origin Access Control (OAC) so unauthorized users cannot scrape your bucket, follow our complete step-by-step tutorial on Secure Static Website Hosting on AWS S3 & CloudFront with OAC and Custom SSL.
B. Backend API Service: Amazon EC2 (t2.micro / t3.micro)
You receive 750 hours per month of t2.micro (or t3.micro in regions where t2 is unavailable) for 12 months. Since a month has 744 hours max, you can keep one EC2 instance running 24/7 all month for free.
# EC2 Bootstrap Script (Amazon Linux 2023 / Ubuntu)
#!/bin/bash
sudo apt update -y && sudo apt upgrade -y
sudo apt install -y docker.io docker-compose
sudo systemctl enable --now docker
sudo usermod -aG docker ubuntuTo containerize your backend services and SQLite/PostgreSQL database to run cleanly on this instance, follow Docker for Beginners: How to Containerize a Full-Stack Application. You can also connect automated testing and deployments with Building a Production CI/CD Pipeline with GitHub Actions and Docker.
03. The Top 5 "Hidden" AWS Gotchas That Cause Unexpected Charges
- Unattached Elastic IPs: AWS does NOT charge for Elastic IPs attached to running instances, but charges you hourly if an IP is allocated and unattached!
- NAT Gateways: NAT Gateways cost ~$32/month minimum just for existing, plus data processing. Never launch a NAT Gateway for a personal project; use a free NAT instance or public subnets with security groups instead.
- EBS Volume Snapshots: You get 30 GB of EBS storage free. If you allocate 40 GB across instances, you will be billed for the difference.
- Custom Domain Route 53 Hosted Zones: Route 53 costs $0.50 per hosted zone per month (not free). Use Cloudflare for free DNS management instead.
- Forgetting to Tear Down Lab Exercises: Always run
terraform destroyor delete CloudFormation stacks after completing tutorials.
AWS Free Tier Core Allowances & Billing Gotchas
| AWS Service | Monthly Free Allowance | Free Tier Category | Hidden Overage Risk | Recommended Safeguard |
|---|---|---|---|---|
| Amazon EC2 | 750 hours (t2.micro / t3.micro) | 12 Months Free | Running 2 instances simultaneously drains hours | Run strictly 1 instance 24/7 or stop when idle |
| Amazon S3 | 5 GB Storage, 20k GET requests | 12 Months Free | High-resolution uncompressed asset storage | Compress images to WebP/AVIF before upload |
| Amazon CloudFront | 1 TB (1,000 GB) Data Transfer Out | Always Free | Direct S3 traffic bypasses CloudFront cache | Enforce Origin Access Control (OAC) |
| Elastic IP Addresses | Free only while attached to running EC2 | N/A | $0.005/hour charged if allocated & unattached | Release unused IPs immediately in AWS Console |

05. Conclusion & Next Steps
The AWS Free Tier is an extraordinary resource for engineers building portfolio projects, experimenting with cloud architectures, or running low-traffic staging systems without spending a dollar. By configuring zero-spend billing budgets on day one and architecting around Always Free services like CloudFront and Lambda, you can deploy full-stack apps with complete peace of mind.
As your projects mature and begin handling active user traffic, monitor your CloudWatch metrics closely and plan your migration path toward low-cost managed services before your 12-month promotional window expires.
