Fly.io vs AWS: 2026 Comparison
Fly.io and AWS are not peers — they compete in different zones. Fly.io is a purpose-built edge platform: deploy a Dockerfile anywhere in seconds with automatic failover and sub-100ms latency to end users. AWS is a sprawling cloud provider with databases, messaging, ML, and a thousand other services layered on top of EC2. [alternatives](/alternatives) to explore other hosting options.
Comparison dimensions
DX & Deploys
Fly.io: Fly.io's CLI and Docker-native workflow are frictionless; `fly deploy` builds, tests, and ships in one command.
AWS: AWS demands infrastructure-as-code (Terraform, CloudFormation) and a mental model of VPCs, security groups, and IAM; power but friction.
Performance
Fly.io: Fly.io automatically routes traffic to the nearest region and scales across 35+ global locations — flat latency is the default.
AWS: AWS offers similar geographic reach via CloudFront and regional deployments, but requires explicit configuration and cross-region setup.
Pricing
Fly.io: Fly.io's per-request billing and generous free tier ($5/month in credits) mean tiny apps cost pennies.
AWS: AWS's 750 hours/month free tier for t3.micro sounds generous until you layer in data transfer, storage, and managed services.
Scaling
Fly.io: Fly.io's scaling is horizontal and automatic; add memory or CPU with a single config change.
AWS: AWS's autoscaling is powerful but manual tuning (launch templates, target groups, policies) is a full-time skill.
Integrations
Fly.io: Fly.io seamlessly integrates Postgres, Redis, and Upstash storage directly into the CLI.
AWS: AWS's integration library is massive (S3, RDS, ElastiCache, SQS) — breadth is unmatched but discovery is an ocean.
Support
Fly.io: Fly.io's support is helpful but limited to the Fly.io-specific ecosystem; you're largely self-reliant for architecture decisions.
AWS: AWS's support tiers are paid; community forums are active but response times scale with your budget.

Decision notes
Choose Fly.io if you're shipping a simple web app, API, or microservice that needs geographic redundancy without DevOps overhead. Choose AWS if you're building a complex system needing a data warehouse, queues, caching, or integration with enterprise tools. Try both free tiers — Fly.io's learning curve is steeper, but deployment is faster.
