Doable vs Fly.io
Doable vs Fly.io, global edge versus simple deploys
Fly.io runs your container in 30+ global regions with anycast routing, purpose-built for low-latency global apps. Doable optimises for the opposite end of the spectrum: one command from your AI coding tool, flat pricing, and the option to deploy to your own server.
At a glance
| Feature | Doable | Fly.io |
|---|---|---|
| Multi-region | Single region per deploy | 30+ regions, anycast routing |
| Pricing model | Flat $0 / $15 / $39 | Per-machine + per-volume + per-region usage |
| Config files | None required (auto-detected) | `fly.toml` with region + machine config |
| Bring-your-own server | Yes | No (Fly's own infra only) |
| AI-tool integration | MCP server | CLI-only |
Where Fly.io is the better fit
- ›You need your app running in multiple global regions with sub-50ms anycast routing.
- ›You're comfortable with their region-and-volume-aware deploy model and want fine-grained control over machine sizes.
- ›You want LiteFS or Fly Postgres replicated across regions.
Where Doable is the better fit
- ›Your app doesn't need multi-region, most apps don't, and the configuration overhead is wasted.
- ›You want one command from Claude Code, Codex, or your terminal, no `fly.toml`, no region pickers.
- ›You want flat pricing, no per-machine, per-volume, per-region line items.
- ›You want the same workflow whether you're deploying to managed cloud or a server you own.
Choose Fly.io if…
- •You need true multi-region deploy with anycast routing.
- •You're running stateful workloads with LiteFS or Fly Postgres.
- •You want fine-grained machine control and are comfortable with Fly's config DSL.
Choose Doable if…
- •Your app is single-region (most apps).
- •You want one command from your editor or AI tool.
- •You want flat pricing.
- •You want BYO infrastructure as a first-class option.
FAQ
Can Doable do multi-region?
Not directly today. Doable Cloud runs single-region and BYO supports any number of regions but each project deploys to one server. Multi-region is on the roadmap; for true global apps today, Fly.io is purpose-built for it.
Can I move a Fly.io app to Doable?
Most Fly.io apps move over with a single change: drop the `fly.toml`, run `doable deploy`. The Dockerfile (or auto-detected runtime) does the rest. You lose region distribution; you keep the rest.
No credit card. Deploy your first project in under a minute.
