# Fly.io

> Firecracker microVMs in 35+ regions including Sydney, driven from the CLI.

- Runs OCI images as Firecracker microVMs close to users.
- Genuinely global region list including Sydney, the only container host here where that is true.
- Machines auto-stop and auto-start in a few hundred milliseconds, approximating scale-to-zero.
- flyctl is the best CLI in the category and effectively the only interface: the dashboard is thin by design.

| Overage behaviour | bill | Vendor-claimed | 2026-06-15 | https://fly.io/docs/about/pricing/ | Pure pay-as-you-go with no hard cap. Egress is cheap enough that the exposure is far smaller than the managed hosts. | https://toolweight.com/compare/vercel-alternatives#fly-io--overage_behaviour |
| Bandwidth price | $20/TB | Vendor-claimed | 2026-06-15 | https://fly.io/docs/about/pricing/ | $0.02/GB in North America and Europe. Asia-Pacific and Australia are roughly double, which matters if you deploy to syd. | https://toolweight.com/compare/vercel-alternatives#fly-io--bandwidth_price |
| Price @ 1 TB | $30/mo | Inferred | - | - | About $20 of NA/EU egress plus a shared-CPU Machine. Deploying into syd pushes this closer to $50. | https://toolweight.com/compare/vercel-alternatives#fly-io--price_1tb_egress |
