Skip the Dockerfile. Just run your automation.
Fly.io runs your apps on machines around the world — if you've got a Dockerfile and a fly.toml. Snapdock runs the scheduled scripts and automations you built with neither, watches every run, and explains what broke in plain English.
No servers, no cron jobs, no YAML. Free to start.
Two good tools. Different jobs.
Reach for Fly.io when
- You're deploying full apps or services that need global, low-latency machines.
- You're comfortable with Dockerfiles, fly.toml, and flyctl.
- You want control over regions and machine sizing.
Reach for Snapdock when
- Your thing is a scheduled script or job — not a globally-deployed app.
- You'd rather not write a Dockerfile or run flyctl.
- You want it run and watched, with plain-English alerts.
Snapdock vs Fly.io, line by line
One ships your app worldwide. The other runs and watches your automations.
| Snapdock | Fly.io | |
|---|---|---|
| Getting your code live | Drag the folder in — auto-detected | Dockerfile (or Buildpacks) + fly.toml + flyctl |
| No container config | Auto-detected | Dockerfile & fly.toml |
| No terminal/CLI | Never required | flyctl-driven |
| Scheduled runs (cron-free) | Pick a schedule | Machines / scheduled via config |
| Failure alerts in plain English | “We noticed…” in Slack/email | Logs & metrics you check |
| Errors explained, not stack traces | Yes | Logs |
| Drift detection | Slow jobs & broken creds flagged | No |
| Best for | Scheduled scripts & automations | Globally-deployed apps & services |
| Plain-English weekly digest | Yes | No |
| Your code stays yours | Export anytime, no lock-in | Yes |
The questions you're already asking.
Everything you need to know about Snapdock.
Is Snapdock a replacement for Fly.io? +
They're built for different jobs. Fly.io deploys apps and services on machines around the world; Snapdock runs and watches the scheduled scripts and automations you built, with no containers to configure.
Do I need a Dockerfile? +
No. Snapdock auto-detects how your script runs — there's no Dockerfile or fly.toml to write.
Do I need flyctl? +
No. There's no CLI and no terminal. Drag the folder in and pick a schedule.
What about scheduled jobs? +
Pick a schedule in Snapdock and it runs and watches every run, alerting you in plain English if it drifts or fails.
Which one is cheaper? +
Snapdock has a free tier and nothing to pay when an automation is idle. For globally-deployed apps and services, Fly.io is the right tool; for scheduled automations and scripts, Snapdock is usually cheaper to keep watched.
