Overview
Fly.io lets developers deploy containers close to users with simple CLI workflows and pay-as-you-go infrastructure.
Pros

- Good fit for small services, jobs, and full-stack apps
- Automatic scaling and health checks
- Transparent usage-based billing
Cons
- Less mature ecosystem than AWS or Cloudflare
- Limited support for complex multi-service architectures
