# Fly.io

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

Fly runs OCI images as Firecracker microVMs close to users, with a genuinely global region list that includes Sydney, the only container host in this roster where that is true. Machines auto-stop and auto-start in a few hundred milliseconds, so you can approximate scale-to-zero without a serverless runtime. flyctl is the best CLI in the category and also, effectively, the only interface: the dashboard is thin by design.

Ranked **#9 of 13** on default weights.
| Field | Value | Confidence | Verified | Source | Note |
| --- | --- | --- | --- | --- | --- |
| Frameworks | nextjs, nuxt, sveltekit, astro, dockerfile | Inferred | - | - | - |
| Next.js parity | self-managed | Inferred | - | - | `next start` in a microVM. Multi-region deployments make the per-instance ISR cache a real problem to solve. |
| Runtime model | container | Inferred | - | - | - |
| Fn timeout | - | Inferred | - | - | No platform-imposed request limit, Machines run as long as you keep them running. |
| Cold start | 400 ms | Community-reported | - | - | Auto-stopped Machines wake in a few hundred milliseconds, the closest a container host gets to scale-to-zero. |
| Cron jobs | ◐ | Inferred | - | - | Machines support simple schedules, but there is no first-class cron service, most people run a scheduler process. |
| Preview deploys | ◐ | Inferred | - | - | Review apps are a documented GitHub Action pattern rather than a built-in feature. |
| WAF & DDoS | ◐ | Inferred | - | - | Network-level protection at the anycast edge; no configurable WAF. |
| Observability | included-basic | Inferred | - | - | Managed Prometheus and Grafana are included; log retention is short unless you ship logs out. |
| Sydney region | ● | Vendor-claimed | 2026-06-15 | https://fly.io/docs/reference/regions/ | `syd`. The only container host in this roster with real Australian compute. |
| Monorepo support | ● | Inferred | - | - | - |
| Rollback | redeploy | Inferred | - | - | `fly deploy --image` against a previous tag: a minute or two, not seconds. |
| 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. |
| 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. |
| 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. |
| Build minutes incl. | - | Inferred | - | - | Builds run on a remote builder billed as ordinary compute. |
| Image opt billing | byo | Inferred | - | - | - |
| Analytics cost | - | Inferred | - | - | - |
| Free tier | 2 | Community-reported | - | - | The standing free allowance was withdrawn in late 2024; new accounts get trial credit. |
| Self-hostable | ○ | Inferred | - | - | - |
| Exit friction | 2 | Inferred | - | - | fly.toml and Fly Postgres are the only things to replace; the image is yours. |
| CLI quality | 5 | Inferred | - | - | flyctl is the best CLI here and, by design, close to the only interface. |
| Agent/CI deploy | ● | Inferred | - | - | - |
| GA year | 2020 | Inferred | - | - | - |
| Funding | growth | Inferred | - | - | - |
| Pricing clarity | 3 | Inferred | - | - | - |

**Verdict.** The right answer for Australian teams who want containers: the only host in this roster with real Sydney compute and cheap egress in the same product. The cost is that cron, previews and observability are patterns you assemble rather than features you switch on.
