Fly.io
The pick for founders who want Vercel-level deploy ergonomics but for real backends, not just frontends. Postgres, Redis, full apps in one platform, all co-located. Pricing is usage-based, which either saves you a fortune or surprises you depending on traffic shape.
❦ Score breakdown
8.8 / 10
`fly launch` ships any Dockerfile in 2–3 minutes.
8.0 / 10
CLI-first; dashboard improving but secondary to CLI.
7.5 / 10
Per-resource model is honest but requires modeling.
8.5 / 10
Native Postgres, Redis, machines, volumes, Tigris object storage.
9.0 / 10
$5/mo gets you a real app online. Hard to beat.
Strengths and tradeoffs
Strengths
- ●Co-locate compute and databases in 35+ regions — real multi-region without AWS pain
- ●Managed Postgres + Redis included on the platform — no separate provider hop
- ●Pricing is per-resource and honest — no surprise tier upgrades
- ●Deploy any Dockerfile — escape-hatch from framework lock-in
Tradeoffs
- ●Documentation is uneven — community Discord fills the gaps
- ●Pricing model takes effort to model upfront
- ●Console / dashboard still trails the CLI in feature parity
What it does
- ●Deploys full apps (any language, any framework) to 35+ global regions
- ●Managed Postgres, Redis, and volumes — no separate DB provider needed
- ●Single-binary deploys via `fly launch` — production in under 5 minutes

Known limitations

“Pricing model takes a minute to understand. Once you do, it's the best deal in cloud.”
“Documentation is sparse in places. Discord community fills the gaps.”
