At a glance
| Vercel | Fly.io Machines | |
|---|---|---|
| Best for | Next.js and frontend apps where you want deploys and previews to just work. | Dockerized apps that want low cost, fine control, or multi-region placement. |
| How deploys work | Connect the Git repo; every push builds and deploys with a preview URL per branch. | fly launch builds the image and deploys it; configuration lives in fly.toml and the flyctl CLI. |
| The tradeoff | Usage pricing past the credit can climb fast with real traffic, especially data transfer. | You operate more of the stack yourself — especially the database. |
| Free tier | Hobby: free for personal, non-commercial projects — 100 GB data transfer, 1M function invocations, and 4 active CPU hours per month. | None |
What you'd realistically pay
| Project stage | Vercel | Fly.io Machines | Cheaper |
|---|---|---|---|
| Just starting | Free Hobby | ≈$3/mo shared-cpu-1x, 256 MB | Vercel |
| Steady traffic | ≈$20/mo Pro | ≈$6/mo shared-cpu-1x, 1 GB | Fly.io Machines |
| Growing | ≈$40/mo Pro + usage | ≈$12/mo Two 1 GB Machines | Fly.io Machines |

Deploy workflow
| Vercel | Fly.io Machines | |
|---|---|---|
| Deploy from Git push | Yes Connect GitHub, GitLab, or Bitbucket; every push deploys. | Partial No native git integration; the documented path is flyctl in GitHub Actions. |
| Preview deploys | Yes Automatic preview URL for every branch and pull request. | Partial PR apps work via the official GitHub Action, not out of the box. |
| Official CLI | Yes The vercel CLI deploys, manages env vars, and streams logs. | Yes flyctl does everything: launch, deploy, scale, ssh, logs. |
| Instant rollbacks | Yes Instant rollback to any previous deployment from the dashboard. | Partial Redeploy any previous image; no one-click dashboard rollback. |
Platform
| Vercel | Fly.io Machines | |
|---|---|---|
| Custom domains + HTTPS | Yes Unlimited domains with automatic TLS on all plans. | Yes Custom domains with free managed certificates. |
| Built-in CDN / edge network | Yes Global edge network serves static assets and caches responses. | Partial Anycast routing sends users to the nearest region, but there is no static-asset CDN. |
| Serverless functions | Yes Serverless and edge functions are the core compute model. | No Machines are micro-VMs, not functions. |
| Docker containers | No No container deploys — code must fit the serverless build. | Yes A Docker image is the deployment unit. |
| SSH / shell access | No No shell; debugging happens through logs and tracing. | Yes fly ssh console opens a shell in any running Machine. |
| EU hosting region | Yes Function region is selectable, including EU locations. | Yes Amsterdam, Paris, Frankfurt, London, and more. |
Runtime & operations
| Vercel | Fly.io Machines | |
|---|---|---|
| Automatic scaling | Yes Serverless scales per request with no configuration. | Yes Machines autostart and autostop with traffic; scale counts per region. |
| Scale to zero | Yes Functions cost nothing while idle by design. | Yes Stopped Machines cost only their storage. |
| Scheduled jobs | Yes Cron jobs trigger functions; Hobby is limited to 2 daily crons. | Partial Scheduled Machines run on fixed intervals; full cron needs a workaround. |
| Managed database | Partial No own database — the marketplace resells Neon, Supabase, Upstash, and others. | Partial Fly Postgres is automated-but-unmanaged; managed options come from partners like Supabase and Upstash. |
| Logs & metrics built in | Yes Runtime logs and Web Analytics built in; deeper observability is a paid add-on. | Yes Built-in metrics (Grafana), live logs, and log shipping. |
Watch out for
Vercel
- The free Hobby plan does not allow commercial projects.
- Pro usage beyond the included $20 monthly credit bills on demand: edge requests from $2 per million, fast data transfer from $0.15/GB after the first 1 TB.
- Every additional team member who deploys costs $20/month.
Fly.io
- New pay-as-you-go organizations get no free allowance.
- Fly Postgres is explicitly unmanaged: automated but not a managed database service — backups and failover are your responsibility.
- Per-second compute plus $0.02/GB egress makes bills variable; prices differ by region.
